• Sending JSON content type in from JavaScript objects ( jQuery ajax )

  - by smartnut007

  I am having trouble sending JavaScript objects as a http request that only accepts json content-type. i.e "application/json" or "text/json" But, I am not sure why data2 ( stringified json ) works fine But, data1 ( json object ) does throws 400 ( Bad Request ). i.e I am not sure jQuery does not serialize the json object to a valid json string for the server to process. var data1 = ({ rating : 3 }); //does not work var data2 = '{ "rating" : 3}'; //works fine $.ajax({ url : "/rate", data : data1, type : "POST", contentType: "application/json", success: function(json){ console.log("Ajax Return :"+json); } });

• Displaying JSON in your Browser

  - by Rick Strahl

  Do you work with AJAX requests a lot and need to quickly check URLs for JSON results? Then you probably know that it’s a fairly big hassle to examine JSON results directly in the browser. Yes, you can use FireBug or Fiddler which work pretty well for actual AJAX requests, but if you just fire off a URL for quick testing in the browser you usually get hit by the Save As dialog and the download manager, followed by having to open the saved document in a text editor in FireFox. Enter JSONView which allows you to simply display JSON results directly in the browser. For example, imagine I have a URL like this: http://localhost/westwindwebtoolkitweb/RestService.ashx?Method=ReturnObject&format=json&Name1=Rick&Name2=John&date=12/30/2010 typed directly into the browser and that that returns a complex JSON object. With JSONView the result looks like this: No fuss, no muss. It just works. Here the result is an array of Person objects that contain additional address child objects displayed right in the browser. JSONView basically adds content type checking for application/json results and when it finds a JSON result takes over the rendering and formats the display in the browser. Note that it re-formats the raw JSON as well for a nicer display view along with collapsible regions for objects. You can still use View Source to see the raw JSON string returned. For me this is a huge time-saver. As I work with AJAX result data using GET and REST style URLs quite a bit it’s a big timesaver. To quickly and easily display JSON is a key feature in my development day and JSONView for all its simplicity fits that bill for me. If you’re doing AJAX development and you often review URL based JSON results do yourself a favor and pick up a copy of JSONView. Other Browsers JSONView works only with FireFox – what about other browsers? Chrome Chrome actually displays raw JSON responses as plain text without any plug-ins. There’s no plug-in or configuration needed, it just works, although you won’t get any fancy formatting. [updated from comments] There’s also a port of JSONView available for Chrome from here: https://chrome.google.com/webstore/detail/chklaanhfefbnpoihckbnefhakgolnmc It looks like it works just about the same as the JSONView plug-in for FireFox. Thanks for all that pointed this out… Internet Explorer Internet Explorer probably has the worst response to JSON encoded content: It displays an error page as it apparently tries to render JSON as XML: Yeah that seems real smart – rendering JSON as an XML document. WTF? To get at the actual JSON output, you can use View Source. To get IE to display JSON directly as text you can add a Mime type mapping in the registry:   Create a new application/json key in: HKEY_CLASSES_ROOT\MIME\Database\ContentType\application/json Add a string value of CLSID with a value of {25336920-03F9-11cf-8FD0-00AA00686F13} Add a DWORD value of Encoding with a value of 80000 I can’t take credit for this tip – found it here first on Sky Sander’s Blog. Note that the CLSID can be used for just about any type of text data you want to display as plain text in the IE. It’s the in-place display mechanism and it should work for most text content. For example it might also be useful for looking at CSS and JS files inside of the browser instead of downloading those documents as well. © Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  AJAX

• An ideal way to decode JSON documents in C?

  - by AzizAG

  Assuming I have an API to consume that uses JSON as a data transmission method, what is an ideal way to decode the JSON returned by each API resource? For example, in Java I'd create a class for each API resource then initiate an object of that class and consume data from it. for example: class UserJson extends JsonParser { public function UserJson(String document) { /*Initial document parsing goes here...*/ } //A bunch of getter methods . . . . } The probably do something like this: UserJson userJson = new UserJson(jsonString);//Initial parsing goes in the constructor String username = userJson.getName();//Parse JSON name property then return it as a String. Or when using a programming language with associative arrays(i.e., hash table) the decoding process doesn't require creating a class: (PHP) $userJson = json_decode($jsonString);//Decode JSON as key=>value $username = $userJson['name']; But, when I'm programming in procedural programming languages (C), I can't go with either method, since C is neither OOP nor supports associative arrays(by default, at least). What is the "correct" method of parsing pre-defined JSON strings(i.e., JSON documents specified by the API provider via examples or documentation)? The method I'm currently using is creating a file for each API resource to parse, the problem with this method is that it's basically a lousy version of the OOP method, as it looks exactly like the OOP method but doesn't provide any OOP benefits(e.g., can't pass an object of the parser, etc.). I've been thinking about encapsulating each API resource parser file in a publicly accessed structure(pointing all functions/publicly usable variables to the structure) then accessing the parser file code from within the structure(parser.parse(), parser.getName(), etc.). As this way looks a bit better than the my current method, it still just a rip off the OOP way, isn't it? Any suggestions for methods to parse JSON documents on procedural programming lanauges? Any comments on the methods I'm currently using(either 3 of them)?

• boost spirit semantic action parameters

  - by lurscher

  Hi, in this article about boost spirit semantic actions it is mentioned that There are actually 2 more arguments being passed: the parser context and a reference to a boolean ‘hit’ parameter. The parser context is meaningful only if the semantic action is attached somewhere to the right hand side of a rule. We will see more information about this shortly. The boolean value can be set to false inside the semantic action invalidates the match in retrospective, making the parser fail. All fine, but i've been trying to find an example passing a function object as semantic action that uses the other parameters (parser context and hit boolean) but i haven't found any. I would love to see an example using regular functions or function objects, as i barely can grok the phoenix voodoo

• Parsing JSON file with Python -> google map api

  - by Hannes

  Hi all, I am trying to get started with JSON in Python, but it seems that I misunderstand something in the JSON concept. I followed the google api example, which works fine. But when I change the code to a lower level in the JSON response (as shown below, where I try to get access to the location), I get the following error message for code below: Traceback (most recent call last): File "geoCode.py", line 11, in test = json.dumps([s['location'] for s in jsonResponse['results']], indent=3) KeyError: 'location' How can I get access to lower information level in the JSON file in python? Do I have to go to a higher level and search the result string? That seems very weird to me? Here is the code I have tried to run: import urllib, json URL2 = "http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false" googleResponse = urllib.urlopen(URL2); jsonResponse = json.loads(googleResponse.read()) test = json.dumps([s['location'] for s in jsonResponse['results']], indent=3) print test Thank you for your responses.

• Syncing client and server CRUD operations using json and php

  - by Justin

  I'm working on some code to sync the state of models between client (being a javascript application) and server. Often I end up writing redundant code to track the client and server objects so I can map the client supplied data to the server models. Below is some code I am thinking about implementing to help. What I don't like about the below code is that this method won't handle nested relationships very well, I would have to create multiple object trackers. One work around is for each server model after creating or loading, simply do $model->clientId = $clientId; IMO this is a nasty hack and I want to avoid it. Adding a setCientId method to all my model object would be another way to make it less hacky, but this seems like overkill to me. Really clientIds are only good for inserting/updating data in some scenarios. I could go with a decorator pattern but auto generating a proxy class seems a bit involved. I could use a generic proxy class that uses a __call function to allow for original object data to be accessed, but this seems wrong too. Any thoughts or comments? $clientData = '[{name: "Bob", action: "update", id: 1, clientId: 200}, {name:"Susan", action:"create", clientId: 131} ]'; $jsonObjs = json_decode($clientData); $objectTracker = new ObjectTracker(); $objectTracker->trackClientObjs($jsonObjs); $query = $this->em->createQuery("SELECT x FROM Application_Model_User x WHERE x.id IN (:ids)"); $query->setParameters("ids",$objectTracker->getClientSpecifiedServerIds()); $models = $query->getResults(); //Apply client data to server model foreach ($models as $model) { $clientModel = $objectTracker->getClientJsonObj($model->getId()); ... } //Create new models and persist foreach($objectTracker->getNewClientObjs() as $newClientObj) { $model = new Application_Model_User(); .... $em->persist($model); $objectTracker->trackServerObj($model); } $em->flush(); $resourceResponse = $objectTracker->createResourceResponse(); //Id mappings will be an associtave array representing server id resources with client side // id. //This method Dosen't seem to flexible if we want to return additional data with each resource... //Would have to modify the returned data structure, seems like tight coupling... //Ex return value: //[{clientId: 200, id:1} , {clientId: 131, id: 33}];

• JavaScript - Building JSON object

  - by user208662

  Hello, I'm trying to understand how to build a JSON object in JavaScript. This JSON object will get passed to a JQuery ajax call. Currently, I'm hard-coding my JSON and making my JQuery call as shown here: $.ajax({ url: "/services/myService.svc/PostComment", type: "POST", contentType: "application/json; charset=utf-8", data: '{"comments":"test","priority":"1"}', dataType: "json", success: function (res) { alert("Thank you!"); }, error: function (req, msg, obj) { alert("There was an error"); } }); This approach works. But, I need to dynamically build my JSON and pass it onto the JQuery call. However, I cannot figure out how to dynamically build the JSON object. Currently, I'm trying the following without any luck: var comments = $("#commentText").val(); var priority = $("#priority").val(); var json = { "comments":comments,"priority":priority }; $.ajax({ url: "/services/myService.svc/PostComment", type: "POST", contentType: "application/json; charset=utf-8", data: json, dataType: "json", success: function (res) { alert("Thank you!"); }, error: function (req, msg, obj) { alert("There was an error"); } }); Can someone please tell me what I am doing wrong? I noticed that with the second version, my service is not even getting reached. Thank you

• Can I return JSON from an .asmx Web Service if the ContentType is not JSON?

  - by Click Ahead

  I would like to post a form using ajax and jquery to a .asmx webservice and return the value from the webservice as JSON. I'm using ASP.NET 4.0. I know that in order to return JSON from a webservice the following needs to be set (1) dataType: "json" (2) contentType: "application/json; charset=utf-8", (3) type: "POST" (4) set the Data to something. I have tested this and it works fine (i.e. my webservice returns the data as JSON) if all *four are set*. But, lets say in my case I want to do a standard form post i.e. test1=value1&test2=value2 so the contentType is not JSON but I want back JSON {test1:value1}. This doesn't seem to work because the contentType is "application/x-www-form-urlencoded" not "application/json; charset=utf-8". Can anyone tell me why I can't do this? It seems crazy to me that you have to explicitly send JSON to get JSON back, yet if you don't use JSON (i.e. post urlencoded contenttype) then the webservice will return XML. Any insights are greatly appreciated :)

• Boost::Spirit::Qi autorules -- avoiding repeated copying of AST data structures

  - by phooji

  I've been using Qi and Karma to do some processing on several small languages. Most of the grammars are pretty small (20-40 rules). I've been able to use autorules almost exclusively, so my parse trees consist entirely of variants, structs, and std::vectors. This setup works great for the common case: 1) parse something (Qi), 2) make minor manipulations to the parse tree (visitor), and 3) output something (Karma). However, I'm concerned about what will happen if I want to make complex structural changes to a syntax tree, like moving big subtrees around. Consider the following toy example: A grammar for s-expr-style logical expressions that uses autorules... // Inside grammar class; rule names match struct names... pexpr %= pand | por | var | bconst; pand %= lit("(and ") >> (pexpr % lit(" ")) >> ")"; por %= lit("(or ") >> (pexpr % lit(" ")) >> ")"; pnot %= lit("(not ") >> pexpr >> ")"; ... which leads to parse tree representation that looks like this... struct var { std::string name; }; struct bconst { bool val; }; struct pand; struct por; struct pnot; typedef boost::variant<bconst, var, boost::recursive_wrapper<pand>, boost::recursive_wrapper<por>, boost::recursive_wrapper<pnot> > pexpr; struct pand { std::vector<pexpr> operands; }; struct por { std::vector<pexpr> operands; }; struct pnot { pexpr victim; }; // Many Fusion Macros here Suppose I have a parse tree that looks something like this: pand / ... \ por por / \ / \ var var var var (The ellipsis means 'many more children of similar shape for pand.') Now, suppose that I want negate each of the por nodes, so that the end result is: pand / ... \ pnot pnot | | por por / \ / \ var var var var The direct approach would be, for each por subtree: - create pnot node (copies por in construction); - re-assign the appropriate vector slot in the pand node (copies pnot node and its por subtree). Alternatively, I could construct a separate vector, and then replace (swap) the pand vector wholesale, eliminating a second round of copying. All of this seems cumbersome compared to a pointer-based tree representation, which would allow for the pnot nodes to be inserted without any copying of existing nodes. My question: Is there a way to avoid copy-heavy tree manipulations with autorule-compliant data structures? Should I bite the bullet and just use non-autorules to build a pointer-based AST (e.g., http://boost-spirit.com/home/2010/03/11/s-expressions-and-variants/)?

• Using Freepascal\Lazarus JSON Libraries

  - by Gizmo_the_Great

  I'm hoping for a bit of a "simpletons" demo\explanation for using Lazarus\Freepascal JSON parsing. I've asked a question here but all the replies are "read this" and none of them are really helping me get a grasp because the examples are bit too in-depth and I'm seeking a very simple example to help me understand how it works. In brief, my program reads an untyped binary file in chunks of 4096 bytes. The raw data then gets converted to ASCII and stored in a string. It then goes through the variable looking for certain patterns, which, it turned out, are JSON data structures. I've currently coded the parsing the hard way using Pos and ExtractANSIString etc. But I'vesince learnt that there are JSON libraries for Lazarus & FPC, namely fcl-json, fpjson, jsonparser, jsonscanner etc. https://bitbucket.org/reiniero/fpctwit/src http://fossies.org/unix/misc/fpcbuild-2.6.0.tar.gz:a/fpcbuild-2.6.0/fpcsrc/packages/fcl-json/src/ http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/packages/fcl-json/examples/ However, I still can't quite work out HOW I read my string variable and parse it for JSON data and then access those JSON structures. Can anyone give me a very simple example, to help getting me going? My code so far (without JSON) is something like this: try SourceFile.Position := 0; while TotalBytesRead < SourceFile.Size do begin BytesRead := SourceFile.Read(Buffer,sizeof(Buffer)); inc(TotalBytesRead, BytesRead); StringContent := StripNonAsciiExceptCRLF(Buffer); // A custom function to strip out binary garbage leaving just ASCII readable text if Pos('MySearchValue', StringContent) > 0 then begin // Do the parsing. This is where I need to do the JSON stuff ...

• ajax upload cannot process JSON response or gives download popup

  - by Jorre

  I'm using the AJAX plugin from Andris Valums: AJAX Upload ( http://valums.com/ajax-upload/ ) Copyright (c) Andris Valums It works great, except for the fact that I cannot send proper JSON as a response. I'm setting the headers to 'Content-Type', 'application/json' before sending the JSON-encoded response, and in the plugin I'm saying that I'm expecting JSON: responseType: "json", This gives me a download popup asking to download the JSON/REPONSE file. The strange thing is, when I don't ass the correct "Content-Type" to my response, it works. Of course I want to pass the correct response type, because all my jQuery 1.4 calls are depending on correct JSON. Does anyone else have had this same problem or is there anyone out there willing to try this out ? I'd love to use this plugin but only when I can return proper JSON with the correct content-type Thanks for all your help!

• JSON Post To Rails From Android

  - by Stealthnh

  I'm currently working on an android app that interfaces with a Ruby on Rails app through XML and JSON. I can currently pull all my posts from my website through XML but I can't seem to post via JSON. My app currently builds a JSON object from a form that looks a little something like this: { "post": { "other_param": "1", "post_content": "Blah blah blah" } } On my server I believe the Create method in my Posts Controller is set up correctly: def create @post = current_user.posts.build(params[:post]) respond_to do |format| if @post.save format.html { redirect_to @post, notice: 'Post was successfully created.' } format.json { render json: @post, status: :created, location: @post } format.xml { render xml: @post, status: :created, location: @post } else format.html { render action: "new" } format.json { render json: @post.errors, status: :unprocessable_entity } format.xml { render xml: @post.errors, status: :unprocessable_entity } end end end And in my android app I have a method that takes that JSON Object I posted earlier as a parameter along with the username and password for being authenticated (Authentication is working I've tested it, and yes Simple HTTP authentication is probably not the best choice but its a quick and dirty fix) and it then sends the JSON Object through HTTP POST to the rails server. This is that method: public static void sendPost(JSONObject post, String email, String password) { DefaultHttpClient client = new DefaultHttpClient(); client.getCredentialsProvider().setCredentials(new AuthScope(null,-1), new UsernamePasswordCredentials(email,password)); HttpPost httpPost = new HttpPost("http://mysite.com/posts"); JSONObject holder = new JSONObject(); try { holder.put("post", post); StringEntity se = new StringEntity(holder.toString()); Log.d("SendPostHTTP", holder.toString()); httpPost.setEntity(se); httpPost.setHeader("Content-Type","application/json"); } catch (UnsupportedEncodingException e) { Log.e("Error",""+e); e.printStackTrace(); } catch (JSONException js) { js.printStackTrace(); } HttpResponse response = null; try { response = client.execute(httpPost); } catch (ClientProtocolException e) { e.printStackTrace(); Log.e("ClientProtocol",""+e); } catch (IOException e) { e.printStackTrace(); Log.e("IO",""+e); } HttpEntity entity = response.getEntity(); if (entity != null) { try { entity.consumeContent(); } catch (IOException e) { Log.e("IO E",""+e); e.printStackTrace(); } } } Currently when I call this method and pass it the correct JSON Object it doesn't do anything and I have no clue why or how to figure out what is going wrong. Is my JSON still formatted wrong, does there really need to be that holder around the other data? Or do I need to use something other than HTTP POST? Or is this just something on the Rails end? A route or controller that isn't right? I'd be really grateful if someone could point me in the right direction, because I don't know where to go from here.

• How do you deal with the conflict between ActiveSupport::JSON and the JSON gem?

  - by Luke Francl

  I am stumped with this problem. ActiveSupport::JSON defines to_json on various core objects and so does the JSON gem. However, the implementation is not the same -- the ActiveSupport version takes arguments and the JSON gem version doesn't. I installed a gem that required the JSON gem and my app broke. The issue is that I'm using to_json in a controller that returns a list of objects, but I want to control which attributes are returned. When code anywhere in my system does require 'json' I get this error message: TypeError: wrong argument type Hash (expected Data) I tried a couple of things that I read online to fix it, but nothing worked. I ended up re-writing the gem to use ActiveSupport::JSON.decode instead of JSON.parse. This works but it's not sustainable...I can't be forking gems every time I want to use a gem that requires the JSON gem. Update: The best solution of this problem is to upgrade to Rails 2.3 or higher, which fixed it.

• How to assert/unit-test servers JSON response?

  - by shazax

  My current project uses JSON as data interchange format. Both Front-end and Back-end team agree upon a JSON structure before start integrating a service. At times due to un-notified changes in JSON structure by back-end team; it breaks the front-end code. Is there any external library that we could use to compare a mock JSON (fixture) with servers JSON response. Basically it should assert the whole JSON object and should throw an error if there is any violation in servers JSON format. Additional info: App is built on JQuery consuming REST JSON services.

• How to deserialize JSON text into a date type using Windows 8 JSON.parse?

  - by canderso

  I'm building a Windows 8 Metro app (aka "Modern UI Style" or "Windows Store app") in HTML5/JavaScript consuming JSON Web Services and I'm bumping into the following issue: in which format should my JSON Web Services serialize dates for the Windows 8 Metro JSON.parse method to deserialize those in a date type? I tried: sending dates using the ISO-8601 format, (JSON.parse returns a string), sending dates such as "/Date(1198908717056)/" as explained here (same result). I'm starting to doubt that Windows 8's JSON.parse method supports dates as even when parsing the output of its own JSON.stringify method does not return a date type. Example: var d = new Date(); // => a new date var str = JSON.stringify(d); // str is a string => "\"2012-07-10T14:44:00.000Z\"" var date2 = JSON.parse(str); // date2 is a string => "2012-07-10T14:44:00.000Z"

• boost::Spirit Grammar for unsorted schema

  - by Hassan Syed

  I have a section of a schema for a model that I need to parse. Lets say it looks like the following. { type = "Standard"; hostname="x.y.z"; port="123"; } The properties are: The elements may appear unordered. All elements that are part of the schema must appear, and no other. All of the elements' synthesised attributes go into a struct. (optional) The schema might in the future depend on the type field -- i.e., different fields based on type -- however I am not concerned about this at the moment.

• How can I put double quotes inside a string within an ajax JSON response from php?

  - by karlthorwald

  I receive a JSON response in an Ajax request from the server. This way it works: { "a" = "1", "b" = "hello 'kitty'" } But I did not succeed in putting double quotes around kitty. When I convert " to \x22 in the Ajax response, it is still interpreted as " by JavaScript and I cannot parse the JSON. Should I also escape the \ and unescape later (which would be possible)? How to do this? Edit: I am not sure if i expressed it well: I want this string inside of "b" after the parse: hello "kitty" If necessary I could also add an additional step after the parse to convert "b", but I guess it is not necessary, there is a more elegant way so this happens automatically? Edit2: The ajax page is generated by php. I tried several things now to create the value of b, all result in JSON parse error on the page: $b = 'hello "kitty"'; // no 1: //$b = str_replace('"',"\x22",$b); // or no 2: // $b = addslashes($b); // or no 3: //$b = str_replace('"','\"',$b); // or no 4: $b = str_replace('"','\\"',$b); echo '"b" : "' . $b . '"';

• RHEL json gem installation requires make?

  - by Salahuddin559

  When I try to install json gem (gem install json), at first it fails to do so, because of some dev package issue. After fixing it, it fails saying that "sh: make: command not found" and "ERROR: Error installing json: ERROR: Failed to build gem native extension.". Why is it failing on make? Notice this is not Mac, this is in RHEL 5 (4 or 5, not sure). Why is it not able to do some "build gem native extension"?

• Emacs xkcd installation needs JSON 1.4, not found in ELPA

  - by CodeKingPlusPlus

  I tried to install the xkcd emacs package (where you can view an xkcd comic in emacs) and got the following error: Need JSON 1.4, but only 1.2 is available I tried to get JSON 1.4 but I cannot find it in the package manager ELPA. It also says that I have JSON 1.3 built in and installed. A lot of things seem to not work correctly. How can I get xkcd to work inside of emacs? I use Ubuntu 12.04 and Emacs 24.3.

• Can JSON be made easily and safely editable by the non-technical Excel crowd?

  - by glitch

  I'm looking for a data storage format that's very intuitive and easy to edit. It should be ideally targeted towards the same crowd as Excel. At the same time I would like the data structure to be a tree. Ideally this would be JSON, since it offers both the tree aspect and allows for more interesting constructs like arrays. That and parsing libraries for JSON are ubiquitous, so I don't have to reinvent the wheel. The problem is that, at least with a non-specialized text editor, JSON is a giant pain to edit for a non-technical user. I'm thinking along the lines of someone who might have used Excel in the past, but never a real text editor. Someone who might not be comfortable with the idea of preserving JSON syntax by hand. Are there data formats out there that would fit this profile? I'd very much prefer this to be a JSON actually, but then it would require a solid editing tool that would hide the underlying implementation from the user. Think Excel and how it abstracts CSV syntax from the user. The reason I'm looking for something like this is because the team has been working with pretty hierarchical data for a while now and we've hit the limits of how easy it is to represent in simple CSVs without having to create complex rules for how represent hierarchy semantics from each row. Any suggestions?

• Is the escaping provided by the Google-Gson library enough to ensure a safe JSON payload?

  - by Lifetime_Learner

  I am currently using the Google-Gson library to convert Java objects into JSON inside a web service. Once the object has been converted to JSON, it is returned to the client to be converted into a JSON object using the JavaScript eval() function. Is the character escaping provided by the Gson library enough to ensure that nothing nasty will happen when I run the eval() function on the JSON payload? Do I need to HTML Encode the Strings in the Java Objects before passing them to the Gson library? Are there any other security concerns that I should be aware of?
