WebSocketException: The server returned status code '200' when status code '101' was expected.

Hi, I downloaded sample code, sign up Bing Speech - Preview key, and executed sample code exe with command console: SpeechClientSample.exe [test wav file path] en-US Short [my Bing speech key] but I got exception: System.Net.WebSockets.WebSocketException: The server returned status code '200' when status code '101' was expected. Does the service("wss://speech.platform.bing.com/api/service/recognition") have accese limit or something I need setting? Thanks.

You should only get such an error if you are using an https prefix (https://speech.platform.bing.com/api/service/recognition). It will wok only with wss prefix (wss://speech.platform.bing.com/api/service/recognition). I can repro the issue with an https url, but not with wss url.Can you confirm that you get the same behavior ?

@amrmahdi Thanks for reply, yes I'm sure I run it with wss prefix, because origin code is wss, I changed nothing code, only download, build and type arguments and execute command, so I'm confuse ... :S

[amrmahdi]

I could not repro the issue using the sample. Can you provide me with a requestIdentifier (a GUID passed to the RequestMetadata object) ?

[ian90911]

@amrmahdi Here is my GUID :{7dd4e20f-d651-4fc8-b3e3-f60d99133e26} How I get it: At SpeechClientSample.Program.cs, Line 150 var requestMetadata = new RequestMetadata(Guid.NewGuid(), deviceMetadata, applicationMetadata, "SampleAppService"); change to var myguid = Guid.NewGuid(); var requestMetadata = new RequestMetadata(myguid, deviceMetadata, applicationMetadata, "SampleAppService"); And the wav file I use is from another sample project: Cognitive-Speech-STT-Windows-master\samples\SpeechRecognitionServiceExample\whatstheweatherlike.wav

[amrmahdi]

@ian90911 Sorry for the late reply. We still need some details to diagnose the issue. Could you please modify the sample to wrap the RecognizeAsync in a try/catch block as follows

try
{
    await speechClient.RecognizeAsync(new SpeechInput(audio, requestMetadata), this.cts.Token).ConfigureAwait(false);
}
catch (WebException we)
{
    foreach (var header in we.Response.Headers.AllKeys)
    {
        Console.WriteLine("{0} {1}", header, we.Response.Headers[header]);
    }
}

And let me know the output of the console printing above ? Thanks

@amrmahdi Thanks for reply. Here is the output:

@ian90911 sorry that this is taking more than expected. The last request you sent seemed to get 503 actually not the exception you mentioned in the original issue. Could try to repro it again ? If you are still getting the WebSocketException, please reply with a fiddler trace headers for the request, as it will not be caught with the WebException this time.

[ian90911]

@amrmahdi Thanks for reply, here is the fiddler trace header log showed when I execute the command, and seems it get lot of request

after last packet log, console throw the WebSocketException out.

And, I tried to run example at windows 8.1 (before was at windows7) and it just working well, I didn't know that ServerLibrary also need windows before windows 8. sorry for my careless 😓

[amrmahdi]

Oh now worries. Yes it only works on Windows 8+ because of the websockets support. I'll make sure we update the documentation to reflect that.
