  • 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.

  • .NET Windows Live Messenger Connectivity?

    - by Pcstalljr
    Hey there guys, I'm working on an IRC bot project, Trying to integrate Windows live into a bot, And have received messages sent to the channel. But the current problem is that the old messenger API that I had no longer works. And the current API i can only find information about addins (complicated for the end user to set up unless I make an installer), Or contact information. I would like my bot to be stand-alone (no messenger required) and have it log in it self, But I can not find information on the login process anywhere. Any ideas?

    - by Dels
    According to this sample: http://www.codeproject.com/KB/mobile/DeepCast.aspx It's possible to request a gps coordinate (longitude & latitude) including range when sending cellid information (MCC, MNC, towerid, etc) Can someone tell me the actual parameter to request/post to this address? http://www.google.com/glm/mmap It could be something like this http://www.google.com/glm/mmap?mcc=xxx&mnc=xxx&towerid=xxx And i would like to know what response we would get. I have observe OpenCellid website and they provide some nice API to begin with, but i want to know about that in google map too (since they have more completed database). OpenCellID API

  • [C#] Namespace Orginization and Conventions

    - by Bob Dylan
    So I have a little bit of a problem. I working on a project in C# using The StackOveflow API. You can send it a request like so: http://stackoverflow.com/users/rep/126196/2010-01-01/2010-03-13 And get back something like this JSON response: [{"PostUrl":"1167342", "PostTitle":"Are ref and out in C# the same a pointers in C++?", "Rep":10}, {"PostUrl":"1290595", "PostTitle":"Where can I find a good tutorial on bubbling?", "Rep":10} ... So my problem is that I have some methods like GetJsonResponse() which return the above JSON and SaveTempFile() which saves that JSON response to a temporary file for later use. I not sure if I should create a class for them, or what namespace to put them under. Right now my current namespace hierarchy is like so: StackOverflow.Api.Json. So how should I organize these methods/classes/namespaces?

  • How do you prevent brute force attacks on RESTful data services

    - by Adrian Grigore
    Hi, I'm about to implement an RESTful API to our website (based on WCF data services, but that probably does not matter). All data offered via this API belongs to certain users of my server, so I need to make sure only those users have access to my resources. For this reason, all requests have to be performed with a login/password combination as part of the request. What's the recommended approach for preventing brute force attacks in this scenario? I was thinking of logging failed requests denied due to wrong credentials and ignoring requests originating from the same IP after a certain threshold of failed requests has been exceeded. Is this the standard approach, or am I a missing something important? Thanks, Adrian

  • Correct syntax for php inside a feed request

    - by Simon Hume
    Hi guys, I have a very basic query string which passes a ID to a receiving page. On that page, I need to dynamically call the YouTube API, giving my playlistID. I'm having to use PHP for this, and it's a little out of my comfort zone, so hopefully someone can wade in with a quick fix for me. Here is my variable $playlist; And I need to replace the 77DC230FBBCE4D58 below with that variable. $feedURL = 'http://gdata.youtube.com/feeds/api/playlists/77DC230FBBCE4D58?v=2'; Any help, as always, greatly appreciated!

  • Java playback of 24 bit audio is incorrect

    - by Paul Hampson
    I am using the javax sound API to implement a simple console playback program based on http://www.jsresources.org/examples/AudioPlayer.html. Having tested it using a 24 bit ramp file (each sample is the last sample plus 1 over the full 24 bit range) it is evident that something odd is happening during playback. The recorded output is not the contents of the file (I have a digital loopback to verify this). It seems to be misinterpreting the samples in some way that causes the left channel to look like it is having some gain applied to it and the right channel looks like it is being attenuated. I have looked into whether the PAN and BALANCE controls need setting but these aren't available and I have checked the windows xp sound system settings. Any other form of playback of this ramp file is fine. If I do the same test with a 16bit file it performs correctly with no corruption of the stream. So does anyone have any idea why the Java Sound API is modifying my audio stream?

  • MLS Integration (RETSBond RI or?)

    - by prodigitalson
    I'm looking Specifically for some detailed information on RETSBond Integrator (RI) or something similar. Has anyone used it? Drawbacks? benefits? What I need is something that provides a PHP API out of the box or some kind of RPC exposure. This thing seems to provide an API for batching the MLS server and putting in my own DB which is acceptable although ideally I'd prefer something totally external. Do any MLS services provide that that you are aware of? I realize this is somewhat subjective but I'm looking for a starting point on different services/vendors to research.

  • Vimeo - videos.getChannels

    - by brad
    How can I efficiently retrieve a list of channels that a Vimeo video is listed in from the Advanced Vimeo API? The Advanced Vimeo API provides the methods channels.addVideo and channels.removeVideo for managing the channels a video belongs to. Also, the channels.getVideos method is provided for retrieving the list of videos belonging to a channel. However, there is no videos.getChannels method. This means that in order to find all the channels a video is included in one would need to call channels.getVideos (possibly more than once if the channel has more than 50 videos) for each channel of interest. This seems terribly inefficient.

  • [PHP] DOMDocument load on a page returning 400 Bad Request status

    - by PeteWilliams
    Hiya, I'm trying to use the Last.fm API for an application I'm creating, but am having some problems with validation. If an API request gives an error it returns a code and message in the response XML like this: <lfm status="failed"> <error code="6">No user with that name</error> </lfm> However, the request also returns an HTTP status of 400 (or in some cases 403) which DOMDocument considers an error and so then refuses to parse the XML. Is there any way round this, so that I can retrieve the error code and message? Thanks Pete

  • Tough question on WPF, Win32, MFC

    - by Mack
    Let's suppose you're an IT student with a basic knowledge of C++ and C#. Let's suppose that you want to design apps that: need to deliver some performance like archivers, cryptographic algorithms, codecs make use of some system calls have a gui and you want to learn an Api that will enable you to write apps like those described earlier and: is mainstream is future proof entitles you to find a decent job is easy enough - I mean easy like VCL, not easy like winapi So, making these assumptions, what Api will you choose? MFC, WPF, other? I really like VCL and QT, but they're not mainstream and I think few employers will want you to write apps in QT or Visual C++ Builder... Thanks for answers.

  • JavaDoc to (Doku)Wiki conversion / doclet

    - by gamma
    Our company has a very large public Java API which is currently being released standalone and online using (of course) JavaDoc. It is surrounded by product documentation which links into the API. We are moving our static documentation to DokuWiki - which works pretty good - and want to keep the links. Now it would be good to have a method (or doclet) that exports the JavaDoc directly into DokuWiki - or a very near alternative. Question: Is there something like this or do you know a method to do just that?

  • How to tell if a user is a fan of the fan page

    - by Dominic Godin
    Hi, I'm working on a FBML fan page for a client. I need to perform a check to see if the current user is a fan of the page. I tried using the JavaScript API but I've found this is not compatible with FBML. I have looked through the FBML page on the developer wiki and found checks for practically everything else but no is user fan check. Any pointers in the right direction would be most appreciated. Thanks in advance.

  • Using the WordPress HTTP_API (wp_remote_get) with GZiped data.

    - by Volmar
    Hi i working on a wordpress plugin where i'm getting data from a remote API. at irst i used cURL, but after reading this blogpost i started using WordPress HTTP_API instead. but i've got onw problem. The API answers are Gziped, and i havn't figured out how to decompress them. The Codex page is talking about an argument called decompress, but i've tried it in alot of ways but i don't get it right. I used this code in cURL: $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_ENCODING, "gzip"); $result = curl_exec($curl); curl_close($curl); anyone knows a way to do the same thing with the HTTP_API?

  • Constructor versus setter injection

    - by Chris
    Hi, I'm currently designing an API where I wish to allow configuration via a variety of methods. One method is via an XML configuration schema and another method is through an API that I wish to play nicely with Spring. My XML schema parsing code was previously hidden and therefore the only concern was for it to work but now I wish to build a public API and I'm quite concerned about best-practice. It seems that many favor javabean type PoJo's with default zero parameter constructors and then setter injection. The problem I am trying to tackle is that some setter methods implementations are dependent on other setter methods being called before them in sequence. I could write anal setters that will tolerate themselves being called in many orders but that will not solve the problem of a user forgetting to set the appropriate setter and therefore the bean being in an incomplete state. The only solution I can think of is to forget about the objects being 'beans' and enforce the required parameters via constructor injection. An example of this is in the default setting of the id of a component based on the id of the parent components. My Interface public interface IMyIdentityInterface { public String getId(); /* A null value should create a unique meaningful default */ public void setId(String id); public IMyIdentityInterface getParent(); public void setParent(IMyIdentityInterface parent); } Base Implementation of interface: public abstract class MyIdentityBaseClass implements IMyIdentityInterface { private String _id; private IMyIdentityInterface _parent; public MyIdentityBaseClass () {} @Override public String getId() { return _id; } /** * If the id is null, then use the id of the parent component * appended with a lower-cased simple name of the current impl * class along with a counter suffix to enforce uniqueness */ @Override public void setId(String id) { if (id == null) { IMyIdentityInterface parent = getParent(); if (parent == null) { // this may be the top level component or it may be that // the user called setId() before setParent(..) } else { _id = Helpers.makeIdFromParent(parent,getClass()); } } else { _id = id; } } @Override public IMyIdentityInterface getParent() { return _parent; } @Override public void setParent(IMyIdentityInterface parent) { _parent = parent; } } Every component in the framework will have a parent except for the top level component. Using the setter type of injection, then the setters will have different behavior based on the order of the calling of the setters. In this case, would you agree, that a constructor taking a reference to the parent is better and dropping the parent setter method from the interface entirely? Is it considered bad practice if I wish to be able to configure these components using an IoC container? Chris

  • Is it possible to programmatically talk to MSN messenger / Live messenger?

    - by Ceilingfish
    Hi chaps, I've been researching how to interact with the MSN messenger / Live messenger service programmatically and I can't find any real documentation on this. The documentation for the Live services only seem to implement in Javascript (they're here: http://dev.live.com/Messenger/) It would be possible to reverse engineer this API to obtain the web services that it is actually using, but I am guessing that they didn't provide the sources for a reason (which means that those web services aren't meant for direct access). However I can't find any other official APIs that allow programmatic access (more specifically no APIs that mention sockets, web services, or a proper programming language like Java or .Net). Does anyone know if an API like that exists?

  • Using SalesForce's Web Service to create and set the type of a Task

    - by Alan Williamson
    I am successfully creating a Task using the SalesForce API SOAP API through Java. However, my problem is that I can't seem to set the Type of it. They all default to "Call" but I really want them to be "Email". Can someone point me in the direction of where I can do this? I think it is to do with RecordTypeMapping, but i am somewhat confused as to how to use this in my Java code to look up the particular one for Task type. I feel I have got so close with this. I have the correct WSDL that is giving me the extra method on the Task.java class, but no matter what I pass in, it dies. This doesn't seem to be a huge ask, yet i am perplexed as to which dots to join to get it to work Any help would be appreciated. thanks

  • What online brokers offer APIs?

    - by Wilco
    So I'm getting really sick of E*TRADE and, being a developer, would love to find an online broker that offers an API. It would be great to be able to write my own trading tools, and maybe even modify existing ones. Based on my research so far, I've only found one option. Interactive Brokers offers a multi-language API (Java/C++/ActiveX/DDE) and has some fairly decent commission rates to boot. I want to make sure there aren't any other options out there I should be considering. Any ideas? Update: Based on answers so far, here's a quick list... Interactive Brokers Java C++ ActiveX DDE for Excel Pinnacle Trading C++ Perl VB.NET Excel MB Trading
