    Hi! I have worked with unitWeb for one year and everything was fine! But after last update I have the following errors:
    HTTP error unknown url :Server closed the connection:System.IO.IOException: Read failure ---> System.Net.Sockets.SocketException: Operation timed out.
    at System.Net.Sockets.Socket.Receive (System.Byte[] buffer, Int32 offset, Int32 size, SocketFlags flags) [0x00000] in <filename unknown>:0

    This errors rise in HTTP GET and POST requests

    Hello!

    I'm trying to test an iOS app with a tablet configured to use an HTTP proxy, but it seems to ignore the settings. Default Unity WWW class and other web app (Safari) seem to work.

    I suppose there's some stuff missing in UniWeb that's causing the proxy settings to be ignored.

    For specifics, I'm testing HTTPS security with my app using mitmproxy.

    To anyone else needing support I recommend downloading "JetBrains dotPeak" which lets you decompile the DLL to find what you need.

    I was going to purchase this but I found it on GCode for free. If there is support for Unity 3.5 I would buy it.


    Here's the Link: https://code.google.com/p/unityweb/

    Check that the referenced filename is formatted correctly. I get that error when the directories don't exist or when the filename is invalid.

    Thanks for reporting the proxy problem, I will look into this.

    Cookies are supported, using the .NET cookie classes.

    I'm not sure on the specifics of the Graph API, however if it is just HTTP then UniWeb can help with that.

    Decompiling is not needed, when you buy UniWeb you get the source code. Please be aware the GCode version is based on a very old version of UniWeb.

    Not directly, as I don't have those platforms, however UniWeb should work wherever Unity works!

    No extra settings are needed, just use "https://" in the URL.

    The "No such host is known" error seems to indicate that the URL you are attempting to use does not resolve via DNS?

    I'm having a problem implementing this. I've emailed yesterday and no one responded. Anywho, I'm trying to post a form and then get the results but the response.text is a diamond with a "?" In it (unprintable character of some kind). I'm probably doing something wrong but your examples don't fully show how its done.

    Email received, but haven't had time to respond.

    I suspect this is related to a unicode issue which I am in the middle of fixing. In the meantime, you can read the Bytes value instead, and decode it using System.Text.Encoding.UTFEncoding or something similar.

    ok, i found out more information... if i have this:

    w.AddField("d", "EAAAAGMkLIvqpak4jPw4h34Y3Bst1d pq5pe1EFd B1Dh10QE/m2FDwkw8DRHdzrbKczjpdZJVDywJsSyqAzIxDuZf2Z7wnC8QkUGJ1rYU1m6DQvBmwdPbW0oHPmTotRNBdUlQ==");

    then i get the <?>..

    without it, i get the message above (about the length required).

    btw, i am sending encrypted messages to/from the server for an MMO..

    Hi Simon, thanks for your answer, the reason I ask about support for the Graph API is because I'm trying to connect to it and I'm getting this error on the web player:

    Code (csharp):
    1. System.Security.SecurityException: Unable to connect, as no valid crossdomain policy was found
    2.   at System.Net.Sockets.Socket.Connect_internal (IntPtr sock, System.Net.SocketAddress sa, System.Int32 error, Boolean requireSocketPolicyFile) [0x00000] in <filename unknown>:0
    3.   at System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP, Boolean requireSocketPolicy) [0x00000] in <filename unknown>:0
    4.   at System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP) [0x00000] in <filename unknown>:0
    5.   at System.Net.Sockets.TcpClient.Connect (System.Net.IPEndPoint remote_end_point) [0x00000] in <filename unknown>:0
    6.   at System.Net.Sockets.TcpClient.Connect (System.Net.IPAddress[] ipAddresses, Int32 port) [0x00000] in <filename unknown>:0
    This is the code I'm using:

    Code (csharp):
    1. IEnumerator  GetUserInfoUniWeb()
    2. {
    3.     var request = new HTTP.Request("GET", "https://graph.facebook.com/100002347686605?fields=id,name,friends&access_token=" + accessToken);
    4.  
    5.     request.Send();
    6.  
    7.     while(!request.isDone) yield return new WaitForEndOfFrame();
    8.  
    9.     if(request.exception != null)
    10.     {
    11.            Debug.LogError(request.exception);
    12.     }
    13.     else
    14.     {
    15.            var response = request.response;
    16.            Debug.Log(response.status);
    17.        Debug.Log(response.GetHeader("Content-Type"));
    18.        Debug.Log(response.Text);
    19.     }
    20. }
    The same code works fine on iOS. The example also works on the web player if I use WWW instead of UniWeb.
    In the examples says you need to call PrefetchSocketPolicy in order to this to work on the web player, but in my case it doesn't makes any difference.

    I'm missing something?

    Thanks!

    Ok, I guess then that you can't connect to a third party server(like facebook) using sockets if they don't have a policy server running, which seems to be the case with Facebook:

    When I connect to my own server(which is running the socket policy server provided with Unity), I get this

    Code (csharp):
    1. iMac:~ murdock$ telnet 172.16.48.128 843
    2. Trying 172.16.48.128...
    3. Connected to cgwks419.comp.local.
    4. Escape character is '^]'.
    5. <policy-file-request/>
    6. <?xml version="1.0"?>
    7. <cross-domain-policy>
    8.    <allow-access-from domain="*" to-ports="1200-1220"/>
    9. </cross-domain-policy>"Connection closed by foreign host.
    But when I try to fetch the policy file from facebook I get this:

    Code (csharp):
    1. iMac:~ murdock$ telnet graph.facebook.com 843
    2. Trying 31.13.85.16...
    3. Connected to star.c10r.facebook.com.
    4. Escape character is '^]'.
    5. <policy-file-request/>
    6. Connection closed by foreign host.
    I guess I'm stuck with WWW for facebook. I'm still will be using UniWeb to communicate with the game api on my own servers.

    Thanks for your help.

    @Murdock

    Are you saying that there is some kind of support for the policy server on graph.facebook.com, or is it something random running on port 843?

    Hi there,
    I'm facing an issue when trying to update a field in a database. (using ParseInstance.Update())

    Sometimes I can update the value with no problem, but sometimes, apparently if I wait a couple of minutes before sending another update request, I get an error: "HTTP Exception unterminated stream".

    I'm I missing something?

    Thanks in advance

    How do you catch this type of exception? I am using UniParse and it tells me I can't put a yield in a try-catch statement. It effectively causes a crash in my iOS app if I have no internet connection instead of failing gracefully...

    Hi, just to clear things up: does uniweb support Unity Android? I read in the Unity licence comparison page that they do not support .NET sockets in the non-Pro version. Thanks in advance!

    UniWeb requires .NET sockets. If these are not available on your platform, UniWeb will not work. Apart from this issue, there is no known problems when using UniWeb on an Android platform with .NET sockets.

    Hi! I'm getting a strange error while running HTTPS requests to my server from Android device:
    Mono.Security.Protocol.Tls.TlsException: Couldn't complete EndRead
    at Mono.Security.Protocol.Tls.SslStreamBase.EndRead (IAsyncResult asyncResult) [0x00000] in <filename unknown>:0
    at System.Net.Security.SslStream.EndRead (IAsyncResult asyncResult) [0x00000] in <filename unknown>:0
    at System.Net.Security.SslStream.Read (System.Byte[] buffer, Int32 offset, Int32 count) [0x00000] in <filename unknown>:0
    at System.IO.Stream.ReadByte () [0x00000] in <filename unknown>:0
    at HTTP.Response.ReadLine (System.IO.Stream stream) [0x00000] in <filename unknown>:0
    at HTTP.Response.ReadFromStream (System.IO.Stream inputStream) [0x00000] in <filename unknown>:0
    at HTTP.Request.<Send>m__55 (System.Object ) [0x00000] in <filename unknown>:0

    In the editor this requests sequence works good. The exception is strange because it happens during a 1-2Kb request after a successfull series of short (with body <1Kb) requests to the same server. What the reason could be? Google says nothing interesting on this exception message :(

    EDIT: Response size is comparable to request size in my scenario (<1Kb request => <1Kb response, >1Kb request => >1Kb response), so maybe the problem is related somehow with response size rather than request size. One more thing to add: I've checked http logs of my web server and all hung requests seem to be the client side problem because time-taken value is 1 sec max in all cases.

    EDIT2: The Android client fails to read even a single byte, even a response code from the server.

    I have a suspicion that this might be caused by the Keep-Alive connection pooling. If you comment out #USE_KEEPALIVE at the top of Request.cs, does the problem still occur?

    It sounds like you want to create a web server within Unity3D? If so, UniWeb does not do this, it is a client library only.

    This was one of the first things I've done while experimenting. I have to add that I tried read/write timeouts for the TcpClient and SslStream with no luck. When I looked at the SslStream's method causing the exception I was really upset:

    Code (csharp):
    1.  
    2. public override int EndRead(IAsyncResult asyncResult)
    3. {
    4.     this.checkDisposed();
    5.     InternalAsyncResult result = asyncResult as InternalAsyncResult;
    6.     if (result == null)
    7.     {
    8.         throw new ArgumentNullException("asyncResult is null or was not obtained by calling BeginRead.");
    9.     }
    10.     if (!asyncResult.IsCompleted  !asyncResult.AsyncWaitHandle.WaitOne(0x493e0, false))
    11.     {
    12.         throw new TlsException(AlertDescription.InternalError, "Couldn't complete EndRead");
    13.     }
    14.     if (result.CompletedWithError)
    15.     {
    16.         throw result.AsyncException;
    17.     }
    18.     return result.BytesRead;
    19. }
    20.  
    You may notice a hardcoded timeout of 5 minutes in asyncResult.AsyncWaitHandle.WaitOne(0x493e0, false) :(

    I had an issue with UniWeb:

    Do a simple get request on a RESTful server(vuforia vws api), but i do not get a response if i used coroutines:

    Code (csharp):
    1.    
    2.  
    3. //create http get request
    4. HTTP.Request getRequest = new HTTP.Request("GET",url);
    5.        
    6. //send request and wait for response
    7. getRequest.Send();
    8.        
    9. //wait for response, corroutine dont work(why?)
    10. while(!request.isDone) yield return new WaitForEndOfFrame();
    11.        
    12. if(getRequest.exception != null)
    13. {
    14.   Debug.LogError(getRequest.exception);
    15. }
    16. else
    17. {
    18.   HTTP.Response response = getRequest.response;
    19.   //inspect response code
    20.   Debug.Log(response.status);
    21.   //inspect headers
    22.   Debug.Log(response.headers.Get("Content-Type"));
    23.   Debug.Log("Response from server: " + response.Text);
    24. }
    This code doesnt work for me. If i replace:

    Code (csharp):
    1. while(!request.isDone) yield return new WaitForEndOfFrame();
    with:

    Code (csharp):
    1. while(!request.isDone)
    2. {
    3.    //empty
    4. }
    5.  
    The programm does, what i has expected.

    The UniWebExample does work WITH the "yield return null" line, but not my own code.

    The full url of my request is: https://vws.vuforia.com/targets

    Are there any problems with the server i have to fix?

    Thanks for your help!

    Is this an editor script, or a game script?

    It is a gamescript, but after everything worked i have planed to use these functions(upload, update, and so on) within the unity editor.

    EDIT: Got another problem with UniWeb. I do a put request on the vws-server(i have done this before but have to use UniWeb because of mac issues), but the server returns "AuthenticationFailure". It is the same code like before, and if i change "PUT" with "GET" everything is working. But if i use PUT, i get an error from the server. Any ideas why it doesnt worked with UniWeb?

    As i said, I used the HTTPRequest-class before and everything worked, but since i use UniWeb, my put request is rejected by the server...

    EDIT2: Tested all other needed methods: GET, POST, DELETE, everything else worked...

    EDIT3: Ok, dont know why, but now it worked. But i dont find any solution for the coroutine-problem!

    Hi Simon,

    Thank you for making this! Using Parse is vital to my new app so I am really happy.

    I purchased Uniweb and after I put my keys in to UniParse I got these three errors:

    401
    UnityEngine.Debug:Log(Object)
    <Start>c__Iterator0:MoveNext() (at Assets/Plugins/UniParse/Demo/UniParseTest.cs:18)

    An error occured, likely a bad password!
    UnityEngine.Debug:Log(Object)
    <Start>c__Iterator0:MoveNext() (at Assets/Plugins/UniParse/Demo/UniParseTest.cs:26)


    ArgumentNullException: Argument cannot be null.
    Parameter name: s
    System.DateTime.Parse (System.String s, IFormatProvider provider, DateTimeStyles styles) (at /Applications/buildAgent/work/84669f285f6a667f/mcs/class/corlib/System/DateTime.cs:918)
    System.DateTime.Parse (System.String s, IFormatProvider provider) (at /Applications/buildAgent/work/84669f285f6a667f/mcs/class/corlib/System/DateTime.cs:912)
    System.DateTime.Parse (System.String s) (at /Applications/buildAgent/work/84669f285f6a667f/mcs/class/corlib/System/DateTime.cs:907)
    ParseInstance.get_createdAt () (at Assets/Plugins/UniParse/Plugins/ParseClass.cs:204)
    UniParseTest+<Start>c__Iterator0.MoveNext () (at Assets/Plugins/UniParse/Demo/UniParseTest.cs:47)


    Any ideas what I did wrong?

    Thanks again!

    I'm going to need see more code to see what is wrong. The coroutine support is quite fundamental to UniWeb, what are you doing that is different from the usage in the examples?

    Stupid question but I'm gonna ask it anyway. Can I use this when building from mac with the free version of unity for ios and android?

    Hello, I sent a previous post saying that your out-of-the-box demo code does not work with Parse. I paid the money specifically so it would work with Parse. Can you help me? Are you willing to help me?

    Otherwise I will ask for a refund.
