We are sending JsonConvert.SerializeObject(lstobject); to the URL here. lstobject is a large list sent to the url.error also returned after 3 minutes to log error how to make webrequest to wait 5 minutes.
var httpWebRequest = (HttpWebRequest)WebRequest
.Create(ConfigurationManager.AppSettings["JsonPayloadPostUrl"]
.ToString());
httpWebRequest.Timeout = 1000000;
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(jsonPayload);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
}
Ee have used httpWebRequest.Timeout = 1000000; but the server is unable to send request back in less than 5 minutes. How to make request to wait for server for response ?
I might be missing something reading your question, but HTTP 500 server error means that the server has provided a response, saying it encountered some internal issue. So you cannot prevent it by setting a bigger timeout on the Request side.
Following https://www.w3.org/Protocols/HTTP/HTRESP.html
Internal Error 500
The server encountered an unexpected condition which prevented it from
fulfilling the request.
I would say either your request is not properly built, or the server has some application-side issue.
Coming back to the timeout setting way, I think it looks properly. Please note that this time might be taking into account topics like DNS name resolution etc. which in turn might require a bit more time than it seems in the first place. This shouldn't be a problem in your case though, looking at the value you are trying to set.

I am trying to play Widevine encrypted content on an Android TV application using Exoplayer. I have my video URL which is served from a CDN and acquired with a ticket. I have my widevine license URL, a ticket and a auth token for the license server.
I am creating a drmSessionManager, putting the necessary headers needed by the license server as follows:
UUID drmSchemeUuid = C.WIDEVINE_UUID;
mediaDrm = FrameworkMediaDrm.newInstance(drmSchemeUuid);
static final String USER_AGENT = "user-agent";
HttpMediaDrmCallback drmCallback = new HttpMediaDrmCallback("my-license-server", new DefaultHttpDataSourceFactory(USER_AGENT));
keyRequestProperties.put("ticket-header", ticket);
keyRequestProperties.put("token-header", token);
drmCallback.setKeyRequestProperty("ticket-header", ticket);
drmCallback.setKeyRequestProperty("token-header", token);
new DefaultDrmSessionManager(drmSchemeUuid, mediaDrm, drmCallback, keyRequestProperties)
After this Exoplayer handles most of the stuff, the following breakpoints are hit.
response = callback.executeKeyRequest(uuid, (KeyRequest) request);
in class DefaultDrmSession
return executePost(dataSourceFactory, url, request.getData(), requestProperties) in HttpMediaDrmCallback
I can observe that everything is fine till this point, the URL is correct, the headers are set fine.
in the following piece of code, I can observe that the dataSpec is fine, trying to POST a request to the license server with the correct data, but when making the connection the response code returns 405.
in class : DefaultHttpDataSource
in method : public long open(DataSpec dataSpec)
this.dataSpec = dataSpec;
this.bytesRead = 0;
this.bytesSkipped = 0;
transferInitializing(dataSpec);
try {
connection = makeConnection(dataSpec);
} catch (IOException e) {
throw new HttpDataSourceException("Unable to connect to " + dataSpec.uri.toString(), e,
dataSpec, HttpDataSourceException.TYPE_OPEN);
}
try {
responseCode = connection.getResponseCode();
responseMessage = connection.getResponseMessage();
} catch (IOException e) {
closeConnectionQuietly();
throw new HttpDataSourceException("Unable to connect to " + dataSpec.uri.toString(), e,
dataSpec, HttpDataSourceException.TYPE_OPEN);
}
When using postman to make a request to the URL, a GET request returns the following body with a response code of 405.
{
"Message": "The requested resource does not support http method 'GET'." }
a POST request also returns response code 405 but returns an empty body.
In both cases the following header is also returned, which I suppose the request must be accepting GET and POST requests.
Access-Control-Allow-Methods →GET, POST
I have no access to the configuration of the DRM server, and my contacts which are responsible of the DRM server tells me that POST requests must be working fine since there are clients which have managed to get the content to play from the same DRM server.
I am quite confused at the moment and think maybe I am missing some sort of configuration in exoplayer since I am quite new to the concept of DRMs.
Any help would be greatly appreciated.
We figured out the solution. The ticket supplied for the DRM license server was wrong. This works as it is supposed to now and the content is getting played. Just in case anyone somehow gets the same problem or is in need of a basic Widevine content playing code, this works fine at the moment.
Best regards.
Suppose I have a client that continually requests streams from a service, and I want automate testing it. So, as part of the test, I create a service that returns a stream. The following code snippet constructs the response and returns it:
HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(fstream);
response.Content.Headers.ContentType = mediaType;
return response;
This works for the success case where the client calls the API and gets a response in a timely manner. But I also want to simulate some timeout failures.
If I want to simulate timeouts before any part of the response is returned, i can simply add a Thread.Sleep() before return response.
My question is: how can I simulate the timeout case where the service has already started return response? I would like to simulate the service timing out after the response headers have been sent, but before the entirety of fstream is sent.
Maybe try something like this?
var response = HttpContext.Current.Response;
response.Buffer = false;
response.AddHeader("SomeHeader","SomeValue");
response.Write("Some body text.");
System.Threading.Thread.Sleep(WEB_SERVER_TIMEOUT_VALUE + 1);
I have a process where I aggregate data and send a request via a http POST out of a map job. I have to wait for the results. Unfortunately I encounter problems with this approach.
When doing so, there is a loss of data during the sending. We managed to investigate this issue to a point where we know that the communication "destroys" sockets and therefore data is lost. Did anyone has experience in doing http POST requests out of a mapper and what to be aware of?
some sample code; mapper:
public void map(final LongWritable key, final Text value, Context context) throws IOException {
String someData = value.toString();
buffer.add(someData);
if (buffer.size() >= MAX_BUFFER_SIZE) {
emit(buffer);
}
}
}
in "emit" I serialize the data (this is fine, I tested this several times) and send it afterwards; sender:
byte[] received = null;
URL connAddress = new URL(someComponentToBeAdressed);
HttpURLConnection urlConn;
urlConn = (HttpURLConnection) connAddress.openConnection();
urlConn.setDoInput(true);
urlConn.setDoOutput(true);
urlConn.setRequestMethod("POST");
urlConn.setRequestProperty("Content-type", "text/plain");
urlConn.getOutputStream().write(serialized_buffer);
urlConn.getOutputStream().flush();
urlConn.getOutputStream().close();
received = IOUtils.toByteArray(urlConn.getInputStream());
urlConn.disconnect();
thanks in advance
we where able to fix this issue. It was no error in hadoop, the error lies in our apache tomcat configuration some timeouts where set for a to small time period. for some bigger chunks of data we overcome the time for the timeout and get errors. unfortunately the exceptions where not that helpful.
I'm in the process of creating a REST API using HttpListener in .NET (C#). This all works out great, except for one slight issue.
I'm trying to return responses with Status Codes other than OK (200), for instance ResourceNotFound (404).
When I set the StatusCode of the HttpListenerResponse to something other than 200, and create a response body (using HttpListenerResponse.OutputStream), it seems to be resetting the status code to 200. I'm not able to send a response with StatusCode 404 and a message body. However, this should be possible according to the HTTP specs. I'm checking the requests and responses with Fiddler, but I'm not able to get what I'm looking for.
I've had the same problem and found the source of the problem :
If you write the body in the OutputStream before set the StatusCode (or any other property), the response will be sent before the modification is applied !
So, you have to proceed in this order :
public void Send(HttpListenerContext context, byte[] body)
{
// First, set a random status code and other stuffs
context.Response.StatusCode = (int)HttpStatusCode.Unauthorized;
context.Response.ContentType = "text/plain";
// Write to the stream IN LAST (will send request)
context.Response.OutputStream.Write(body, 0, body.Length);
}
I am truing to integrate fusemail in asp.net 2.0. I am using HttpWebRequest for requesting the API pages. It has recently come to my notice that HttpWebRequest fails the first time and then continues and subsequent requests succeed.
say ( i know if i use goto it is a bad programming approach) if i use this code
retry:
try
{
Uri uri = new Uri("http://www.fusemail.com/api/request.html");
if (uri.Scheme == Uri.UriSchemeHttp)
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.PreAuthenticate = true;
request.Method =
WebRequestMethods.Http.Post;
//request.ReadWriteTimeout = System.Threading.Timeout.Infinite;
//request.Timeout = System.Threading.Timeout.Infinite;
request.ContentLength = data.Length;
request.ContentType =
"application/x-www-form-urlencoded";
//request.UserAgent = Request.UserAgent;
request.UserAgent = "Mozilla/4.0";
request.KeepAlive = false;
request.ServicePoint.Expect100Continue = true;
//request.Accept = "Accept: text/html,application/xhtml+xml,application/xml";
StreamWriter writer = new StreamWriter(request.GetRequestStream());
writer.Write(data);
writer.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string tmp = reader.ReadToEnd();
response.Close();
//Response.Write(tmp);
if (!String.IsNullOrEmpty(tmp))
{
return tmp;
}
}
return String.Empty;
}
catch (WebException ex)
{
goto retry;
}
it works after failing once. i am writing to a text file in case of an error and after i failed request it works the second time. I am using ASP.Net 2.0 and the website is hosted on IIS 7 with Windows Server 2008 Standard. Also pinging the API address it fails the first time and then responds

Is there an authentication issue the first time?. i read on some forums it first sends a 401 Unauthorized and then it can connect. I am unable to verify this using Fiddler.
Is there anything wrong with IIS configuration?
This is not a programming issue at all, I have faced a similar problem later and it was a network configuration problem due to ISA server / Firewall settings.
You have to contact your network administrator to check this issue.
I wish this helped you.

I recently came by this same issue. The solution in my case involved my testing environment, since I had multiple Ethernet adapters connected to my computer. While you may have a different IP for each of your Ethernet adapters, if they are all assigned to the same subnet this may cause a problem. The TCP connection is only attempted using one NIC at a time. So in my case, on the first try it would attempt the connection on one adapter that was not connected to my remote host, then on the second try it would connect using the second adapter which was connected. - Hope this helps someone.
