Web Request Error w/ Web API

I have just updated to Unity5 as it showed up and I wanted to see the WebGL stuff. The load times were absurd and the amount of memory required to run it was almost double the required for the web player, so I have opted to just let it be for now and continue with my project using web player.

The problem I am having with web player is that in some browsers (IExplorer and Firefox) the web requests are being replied to with a 415 error from my WebAPI server. The same code (as far as I am aware?) works in the Unity editor and Chrome and Opera.

Opening up Fiddler I looked at the body of the request being sent to the server through Firefox, and it has additional content in the body:

Code (csharp):

1.  
2. Content-Length: 102
3. Content-Type: application/json; charset=utf-8
4. X-Unity-Version: 5.0.0f4
5.  
6. {"Username":"testaccountusername","Password":"asha256password"}
7.  

The response given by the server is:

Code (csharp):

1.  
2. {"Message":"The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource.","ExceptionMessage":"No MediaTypeFormatter is available to read an object of type 'LoginRequest' from content with media type 'application/octet-stream'.","ExceptionType":"System.Net.Http.UnsupportedMediaTypeException","StackTrace":"  at System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\r\n  at System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync(HttpRequestMessage request, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)"}
3.  

This is ONLY occurring in Firefox (and possibly IExplorer).

The segment of code in question from my webserver has the following signature:

Code (csharp):

1.  
2. [Route("api/login")]
3. public IHttpActionResult PostLogin([FromBody] LoginRequest request)
4.  

Any suggestions for resolving or working around it?

 

We have same issue and while investigating in Firefox another Content-lenght header is being sent. In unity 4 everything works ok with this scenario.

Code (CSharp):

1. Content-length: 166
2.  
3. Content-Length: 89
4. Content-Type: application/json
5. X-Unity-Version: 5.0.0f4
6.  
7. {"app_id":"53e3231ecc84c000185","login":"user@user.com","password":"somepassword"}

 

This happens in web player, not in WebGl. This whole scenario works ok in webgl. Please explain a little detailed what these two links can help us with. Also, this only happens in Firefox and Internet Explorer. Chrome has no problems with this.

 

Wow, I completely misread the original post. Sorry. Disregard it.

 

Can someone from the Unity 5 team reply to this thread? Or should we report a bug through Unity 5 ?

 

Same issue here with Webplayer and Firefox on OSX Yosemite. It works just fine with Safari and Chrome.

 

Got the same issue.
This bug report covers it. Please vote and comment:

Any news on this issue? It's been more than two weeks now, and we are really stuck with it.

 

Bump. Same issue.

 

Fix should be included in yesterdays patch Unity5.0.1p1 but unfortunately its not possible to release a game for webplayer with a patch release:
Please be aware that you cannot build and release a Web Player game with a patch release, as the runtime will not be updated with patch versions.

Seems like we have to wait for the official release...

 

Is there an ETA on when this will be? It's really, really affecting our business to not be able to launch on Unity 5 with a web player build because your release cycle won't fix critical show-stopper bugs in a timely fashion.
