After endless research and testing of different combinations, I'm clueless right now.
I receive an WebException: The request timed out
only if I my byteArray
gets filled by something else than System.Text.Encoding.UTF8.GetBytes("")
. (Like "hello")
The server setup is a https-request to a Google Load Balancer, which communicates with the backend via HTTP. The backend is an Apache with PHP.
For testing purposes (self-signed SSL-Cert) I have this:
System.Net.ServicePointManager.ServerCertificateValidationCallback =
delegate (object s,
System.Security.Cryptography.X509Certificates.X509Certificate certificate,
System.Security.Cryptography.X509Certificates.X509Chain chain,
System.Net.Security.SslPolicyErrors sslPolicyErrors){
return true;
};
- If I enter the URL in my web-browser (Chrome), I get a response.
- If I use the HTTP-requester from Mozilla with or without content to send, I get the correct response data (after adding an SSL-Security exception)
- If I run my code below with
System.Text.Encoding.UTF8.GetBytes("")
everything works (except I cannot send data and therefore receive what I want)
Here's the code I'm using.
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("https://someurl.com/some.php");
webRequest.Proxy = null;
webRequest.Credentials = CredentialCache.DefaultCredentials;
webRequest.Method = "POST";
webRequest.Timeout = 3000;
byte[] byteArray = System.Text.Encoding.UTF8.GetBytes("someData"); //works if empty
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = byteArray.Length;
Stream postData = webRequest.GetRequestStream();
postData.Write(byteArray, 0, byteArray.Length);
postData.Close();
HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse(); //ERROR MESSAGE
Stream dataStream = webResponse.GetResponseStream();
reader = new StreamReader(dataStream);
string data = reader.ReadToEnd(); //output data
reader.Close ();
dataStream.Close ();
webResponse.Close ();
The exact error (btw, all this happens in the Unity3D editor):
WebException: The request timed out
System.Net.HttpWebRequest.EndGetResponse (IAsyncResult asyncResult)
System.Net.HttpWebRequest.GetResponse ()
So why on earth is it not working, once there is something the GetRequestStream has to write?
Thanks and all the best, Kruegbert
..::Addendum
- if I increase the timeout, it just takes longer until the same msg appears.
- If I write
webRequest.ContentLength = byteArray.Length+1
I receive a response, but it's a WebException error:ProtocolError
- If I write
webRequest.ContentLength = byteArray.Length-1
I get theProtocolViolationException
- I already tried the same with try/catch/using resulting in the same behaviour
