• Django CSRF framework cannot be disabled and is breaking my site

  - by MikeN

  The django csrf middleware can't be disabled. I've commented it out from my Middleware of my project but my logins are failing due to missing CSRF issues. I'm working from the Django trunk. How can CSRF cause issues if it is not enabled in middleware? I have to disable it because there are lots of POST requests on my site that CSRF just breaks. Any feedback on how I can completely disable CSRF in a django trunk project? The "new' CSRF framework from Django's trunk is also breaking an external site that is coming in and doing a POST on a URL I'm giving them (this is part of a restful API.) I can't disable the CSRF framework as I said earlier, how can I fix this?

• Object mapping in objective-c (iphone) from JSON

  - by freshfunk

  For my iPhone app, I'm consuming a RESTful service and getting JSON. I've found libraries to deserialize this into an NSDictionary. However, I'm wondering if there are any libraries to deserialize the JSON/NSDictionary/Property List into my object (an arbitrary one on my side). The java equivalent would be the object-relational mappers although the sort of object mapping I'm looking for is relatively straightforward (simple data types, no complex relationships, etc.). I noticed that Objective-C does have introspection so it seems theoretically possible but I haven't found a library to do it. Or is there a simple way to load an object from an NSDictionary/Property List object that doesn't require modification every time the object changes? For example: { "id" : "user1", "name" : "mister foobar" "age" : 20 } gets loaded into object @interface User : NSObject { NSString *id; NSString *name; int *age; }

• Calling WCF Service from Action Script 2

  - by Frank

  Hi All, I am a .NET programmer working with a Flash designer on a project. The design is that they will create a flash UI (implemented with AS2) to present a questionnaire. After it is completed by an end user, the will send me (a .net web service of some form) the answers to the questionnaire, I will perform a calculation, and I will send a response back (the response will likely be a single integer, though it may be a touple of (integer score, string description). Neither myself nor the designer is knowledgeable of Action Script. Does anyone have a snippet for such web service calls in AS2? Are there any soap libraries for AS2 that we could use, or should I expose a RESTful interface? Can it be as simple as having the designer concat the questionnaire answers into the query string of the service URL? What would be a typical data format for my response (xml, json, plain text) Thanks in advance for your help. Frank

• Spring MVC Controller redirect using URL parameters instead of in response.

  - by predhme

  I am trying to implement RESTful urls in my Spring MVC application. All is well except for handling form submissions. I need to redirect either back to the original form or to a "success" page. @Controller @RequestMapping("/form") public class MyController { @RequestMapping(method = RequestMethod.GET) public String setupForm() { // do my stuff return "myform"; } @RequestMapping(method = RequestMethod.POST) public String processForm(ModelMap model) { // process form data model.addAttribute("notification", "Successfully did it!"); return "redirect:/form"; } } However as I read in the Spring documentation, if you redirect any parameters will be put into the url. And that doesn't work for me. What would be the most graceful way around this?

• Advice? SSO in N-tiered SOA with mixture of REST and SOAP services

  - by Tyler

  Hi gang, We are moving to SSO in our N-tiered SOA applications. If all the services were SOAP, I'd be ok with just the WS-Security, WS-Trust, WS-Federation set of protocols. My problem is that many of the services are RESTful (ironic) and those protocols do not address REST services. What is your advice for SSO protecting the REST services in an N-tiered SOA architecture with the following requirements: ideally claims-based identity information available to the REST services original user (eg. bootstrap) information must flow through the tiers so that each service can "ActAs" or "OnBehalfOf" the user support sequences like: WebApp -- REST Svc -- SOAP Svc WebApp -- REST Svc1 -- REST Svc2 WebApp -- SOAP Svc -- REST Svc WebApp -- SOAP Svc1 -- SOAP Svc2 support SSO (and SSOff) service/web app platforms: ASP.Net and WCF Java end-user client platforms: .Net (WSE 3.0 and WCF) flash 10 java javascript and AJAX Normally I'm good at climbing / bashing my way through walls, but this one's knocked me flat. Hopefully with your help, we can get over this one. Thanks, Tyler

• How do I interact with OData from Java?

  - by user280638

  OData is Microsoft's repackaging of its Astoria (now WCF Data Services) RESTful query/update protocol. If I want to use Java to create an OData compatible data source, how do I do that? Similarly, if I want to consume an OData data source from Java, how do I do that? http://www.odata.org/ Partial answer below. The OData website suggests that Restlet supports OData. Restlet's API documentation mentions the org.restlet.ext.odata package. www.restlet.org/ www.restlet.org/documentation/snapshot/jee/ext/org/restlet/ext/odata/package-summary.html Is this the only answer? Are there blog posts on doing this integration?

• Why does this call to jQuery's $.ajax() fire an empty request in Chrome and Firefox?

  - by Martin Wiboe

  Hello, I am trying to call a WCF RESTful service from jQuery. I am using JSON to encode both request and response. The following code functions correctly in IE8: url = 'http://ipv4.fiddler:5683/WeatherWCF/NewBinding/MyService/GetValueFloat'; $.ajax({ url: url, data: '{"alias": "Udetemperatur"}', type: "POST", contentType: "application/json; charset=utf-8", dataType: "text", // not "json" we'll parse success: function(res) { alert('Received response: ' + res); } }); However, in both Firefox and Chrome, res contains an empty string. After using Fiddler to monitor the request, it appears that jQuery sends an empty request to the server as shown in this screen dump: http://imgur.com/EJgwS.png This is the successful request: http://imgur.com/S77BA.png What am I doing wrong? Kind regards, Martin

• Middleware for MongoDB or CouchDB with jQuery Ajax/JSON frontend

  - by Tauren

  I've been using the following web development stack for a few years: java/spring/hibernate/mysql/jetty/wicket/jquery For certain requirements, I'm considering switching to a NoSQL datastore with an AJAX frontend. I would probably build the frontend with jQuery and communicate with the web application middleware using JSON. I'm leaning toward MongoDB because of more dynamic query capabilities, but am still considering CouchDB. I'm not sure what to use in the middle. Probably something RESTful? My preference is to stick with Java (or maybe Scala or Groovy) since I'm using tools like Drools for rules and Shiro for security. But then again, I want to pick something that is quick an easy to work with, so I'm open to other solutions. If you are building ajax/json/nosql solutions, I'd like to hear details about what tools you are using and any pros/cons you've found to using them. Thanks!

• Jersey, Spring, Tomcat and Security Annotations

  - by jr

  I need to secure a simple jersey RESTful API in a Tomcat 6.0.24 container. I'd like to keep the authentication with Basic Authentication using the tomcat-users.xml file to define the users and roles (this is for now, like I said its small). Now, for authorization I'd like to be able to use the JSR 250 annotations like @RolesAllowed, @PermitAll, @DenyAll, etc. I cannot for the life of me figure out how to wire this all up together. I really don't want to go spring-security route, since I need something very simple at the current time. Can someone point me in the right direction.

• Optional query string parameters in URITemplate in WCF?

  - by Shafique

  I'm developing some RESTful services in WCF 4.0. I've got a method as below: [OperationContract] [WebGet(UriTemplate = "Test?format=XML&records={records}", ResponseFormat=WebMessageFormat.Xml)] public string TestXml(string records) { return "Hello XML"; } So if i navigate my browser to http://localhost:8000/Service/Test?format=XML&records=10, then everything works as exepcted. HOWEVER, i want to be able to navigate to http://localhost:8000/Service/Test?format=XML and leave off the "&records=10" portion of the URL. But now, I get a service error since the URI doesn't match the expected URI template. So how do I implement defaults for some of my query string parameters? I want to default the "records" to 10 for instance if that part is left off the query string.

• Sending Facebook notifications

  - by antpaw

  Hey i have a little facebook iframe application written with rails and the facebooker plugin. I can loop through the users friends and see whether they also have this application. To do this I use a fql qeury, and my own html (no fbml). Now i want to create a button right beside every friend who doesn't have this app, that sends an invite massage. Is it possible to do this without this FBML/JS voodoo? I looked through the RESTful api but the only thing i could found was this deprecated method :( Can someone provide me an code example on how to do this? I really don't want to use this FBML stuff because it doesn't fit into the ui concept of the app, but if that the only way, please explain how to do this (every fbml tag I've tried is just invisible :( ) Thanks a lot.

• How to pass a very long string/file into RESTWebservice JAX-RS Jersey

  - by Sashikiran Challa

  Hello All, I am trying to write a webservice that takes in an XML string, does parsing of it using DOM and extract particular things I want. My XML string happens to be very long so I do not want to pass it as a @QueryParam or @PathParam. Say If I write that XML string into a file, How do I go about writing a RESTful service that takes in this file, extracts whatever I want and return the results. I am actually trying to extract some number of strings, so my output should probably be an ArrayList having all these strings. Could somebody please shed some light on how I should go about doing this. Thanks in advance

• Rails 3: What is the proper way to respond to REST-ful actions with JSON in rails?

  - by Damien Wilson

  Hello SO. I'm trying to make an API for my rails application using JSON responses to RESTful resource controllers. This is a new experience for me, so I'm looking for some guidance and pointers. To start things off: In a rails application, what is the "proper" way to respond with JSON to REST-ful controller methods? (create, update, destroy) Is there an idiomatic way to indicate success/failure through a JSON response? Additional information: I'm currently working with rails 3.0.beta2 I would like to avoid using a plugin or gem to do the grunt work, my goal is to gain a better understanding of how to make a rails 3 API. Links to places I could find more information on the topic would also be appreciated, some quick searching on google didn't do me much good.

• MVC ActionLink generating NON-Restul URL AFTER adding constraints

  - by brianstewey

  Hello I have a custom route that without constraints generates a Restful URL with an ActionLink. Route - routes.MapRoute( "Blog", // Route name "Blog/{d}/{m}/{y}", // URL with parameters, new { controller = "Blog", action = "Retrieve" } Generates - http://localhost:2875/Blog/12/1/2010 From - <%=Html.ActionLink("Blog Entry - 12/01/2010", "Retrieve", "Blog", new { d = 12, m = 01, y = 2010 }, null)%> If I add constraints like so. routes.MapRoute( "Blog", // Route name "Blog/{d}/{m}/{y}", // URL with parameters, new { controller = "Blog", action = "Retrieve" }, new { d = @"\d{2}", m = @"\d{2}", y = @"\d{4}" } It generates - http://localhost:2875/Blog/Retrieve?d=12&m=1&y=2010 Extra information: it is added before the custom route. Any ideas? Cheers

• Rails choking on the content of this request because of protect_from_forgery

  - by randombits

  I'm trying to simply test my RESTful API with cURL. Using the following invocation: curl -d "name=jimmy" -H "Content-Type: application/x-www-form-urlencoded" http://127.0.0.1:3000/people.xml -i Rails is dying though: ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): :8:in `synchronize' Looks like it's running this through a protect_from_forgery filter. I thought protect_from_forgery is excluded for non-HTML HTTP POST/PUT/DELETE type requests? This is clearly targeting the XML format. If I pass actual XML content, it works. But my users will be submitting POST data as URL encoded parameters. I know all the various ways I can disable protect_from_forgery but what's the proper way of handling this? I want to leave it on so that when I do have HTML based forms and handle format.html, I don't forget to re-enable it for then. I want users to be able to make HTTP POST requests to my XML-based API though and not get bombarded with this.

• Framework for Implementing REST web service in Django

  - by Laizer

  I'm looking to implement a RESTful interface for a Django application. It is primarily a data-service application - the interface will be (at this point) read-only. The question is which Django toolsets / frameworks make the most sense for this task. I see Django-rest and Django-piston. There's also the option of rolling my own. The question was asked here, but a good two years back. I'd like to know what the current state of play is. In this question, circa 2008, the strong majority vote was to not use any framework at all - just create Django views that reply with e.g. JSON. (The question was also addressed, crica 2008, here.) In the current landscape, what makes the most sense?

• MVC2: "File not found" after view is painted

  - by Dave Hanna

  This is wierd. First, I'm building a site based on someone else's framework (Piers Lawson: Creating a RESTful Web Service using MVC ), so I'm not entirely sure what's going on under the covers. But when I run it in VS 2010 by pressing F5, it brings up the Home page, and THEN traps an error in Application_Error. The error is "File does not exist" exception. But I have no idea what file it's looking for. Where does flow control go after the View is finished displaying? How can I break to find out what it's looking for?

• Modify headers in Pylons using Middleware

  - by Anders

  Hi all, I'm trying to modify a header using Middleware in Pylons to make my application RESTful, basically, if the user request "application/json" via GET that is what he get back. The question I have is, the variable headers is basically a long list. Looking something like this: [('Content-Type', 'text/html; charset=utf-8'), ('Pragma', 'no-cache'), ('Cache-Control', 'no-cache'), ('Content-Length','20'), ('Content-Encoding', 'gzip')] Now, I'm looking to just modify the value based on the request - but are these positions fixed? Will 'Content-Type' always be position headers[0][0]? Best Regards, Anders

• Rails, REST Architecture and HTML 5: Cross domain requests with pre-flight requests

  - by Orion

  While working on a project to make our site HTML 5 friendly, we were eager to embrace the new method for Cross Domain requests (no more posting through hidden iframes!!!). Using the Access Control specification we begin setting up some tests to verify the behaviour of various browsers. The current Rails RESTful architecture relies on the four HTTP verbs: GET, POST, PUT, DELETE. However in the Access Control spec, it dictates that non-simple methods (PUT, DELETE) require a pre-flight request using the HTTP verb OPTIONS. In addition during testing we discovered that Firefox 3.5.8 pre-flight POST requests as well. My question is this. Is anyone aware of any project for the Rails framework working to address the issue? If not, any opinions about the best strategy to support the OPTIONS method, since it has to support the routes for all the POST, PUT, DELETE methods?

• Is it possible to implement X-HTTP-Method-Override in ASP.NET MVC?

  - by Greg Beech

  I'm implementing a prototype of a RESTful API using ASP.NET MVC and apart from the odd bug here and there I've achieve all the requirements I set out at the start, apart from callers being able to use the X-HTTP-Method-Override custom header to override the HTTP method. What I'd like is that the following request... GET /someresource/123 HTTP/1.1 X-HTTP-Method-Override: DELETE ...would be dispatched to my controller method that implements the DELETE functionality rather than the GET functionality for that action (assuming that there are multiple methods implementing the action, and that they are marked with different [AcceptVerbs] attributes). So, given the following two methods, I would like the above request to be dispatched to the second one: [ActionName("someresource")] [AcceptVerbs(HttpVerbs.Get)] public ActionResult GetSomeResource(int id) { /* ... */ } [ActionName("someresource")] [AcceptVerbs(HttpVerbs.Delete)] public ActionResult DeleteSomeResource(int id) { /* ... */ } Does anybody know if this is possible? And how much work would it be to do so...?
