  Cannot open host WCF REST Services

  Apr 19, 2011 06:10 AM|monfu|LINK

  Dear All,

  I am trying to implement some WCF and REST service to upload a file on my server, and I have found some code which I am trying to implement but no success yet.

  Basically this is my code :-

   

  class Program
  {
      static void Main(string[] args)
      {
  
          Test();
      }
  
      [ServiceContract]
      public interface ITest
      {
          [OperationContract, WebInvoke(UriTemplate = "UploadFile/{fileName}")]
          void UploadFile(string fileName, Stream fileContents);
      }
  
      public class Service : ITest
      {
          public void UploadFile(string fileName, Stream fileContents)
          {
              byte[] buffer = new byte[10000];
              int bytesRead, totalBytesRead = 0;
              do
              {
                  bytesRead = fileContents.Read(buffer, 0, buffer.Length);
                  totalBytesRead += bytesRead;
              } while (bytesRead > 0);
              Console.WriteLine("Uploaded file {0} with {1} bytes", fileName, totalBytesRead);
          }
      }
  
      public class MyMapper : WebContentTypeMapper
      {
          public override WebContentFormat GetMessageFormatForContentType(string contentType)
          {
              return WebContentFormat.Raw; // always
          }
      }
  
      static Binding GetBinding()
      {
          CustomBinding result = new CustomBinding(new WebHttpBinding());
          WebMessageEncodingBindingElement WebMEBE =
              result.Elements.Find<WebMessageEncodingBindingElement>();
          WebMEBE.ContentTypeMapper = new MyMapper();
          return result;
      }
  
      public static void Test()
      {
          try
          {
              string baseAddress = "http://localhost:1157/Default.aspx";
              var endpointAddress = new Uri(baseAddress);
              ServiceHost host = new ServiceHost(typeof(Service), endpointAddress);
  
              host.AddServiceEndpoint(typeof(ITest), 
                  new WebHttpBinding(), "").Behaviors.Add(new WebHttpBehavior());
              host.Open();
  
              Console.WriteLine("Host opened");
  
              HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(baseAddress + "asd_asd_Feedback.xml");
              req.Method = "POST";
              req.ContentType = "text/xml";
              Stream reqStream = req.GetRequestStream();
              string fileContents = "<hello>world</hello>";
              byte[] fileToSend = Encoding.UTF8.GetBytes(fileContents);
              reqStream.Write(fileToSend, 0, fileToSend.Length);
              reqStream.Close();
              HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
              Console.WriteLine("HTTP/{0} {1} {2}", resp.ProtocolVersion,
                  (int)resp.StatusCode, resp.StatusDescription);
              //host.Close();
  
          }
          catch (Exception exc)
          { 
  
          }
  
      }
  
  }

  and at the moment, when I try to open the host, I am getting the following error :-
  HTTP could not register URL http://+:1157/Default.aspx/ because TCP port 1157 is being used by another application.
  Can anybody point me to the right direction
  Thanks for your help and time

  Hello,

  Please try to host your application in your localhost.

  and then try to host or publish your WCF or REST service.

  Mark as answer if that helps you.
  Thanks & Regards.

  Well I added a virtual directory in IIS called localhost/GetResponse/ and added the files to it, which inclides the GetResponse.svc, but this is never called.

  Can you point me to some example I can follow since I am quite new to WCF.

  My aim is to have an XML file from a windows app posted on my server and found a tutorial how to do that but I am not successful at the moment in implementing it

  Hi bhavik

  So I read some tutorials and published my WCF Service on the localhost at http://localhost/UploadService/UploadService.svc/ and that is loading.

   

  Now I am applying the code as follows :-

   

  string address = "http://localhost/UploadService/UploadService.svc/UploadFile/theFile.txt";
              HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(address);
              req.Method = "POST";
              req.ContentType = "text/plain";
              Stream reqStream = req.GetRequestStream();
              string fileContents = "the quick brown fox jumped over the lazy dog.";
              byte[] bodyContents = Encoding.UTF8.GetBytes(fileContents);
              reqStream.Write(bodyContents, 0, bodyContents.Length);
              reqStream.Close();
  
              HttpWebResponse resp;
              try
              {
                  resp = (HttpWebResponse)req.GetResponse();
              }
              catch (WebException e)
              {
                  resp = (HttpWebResponse)e.Response;
              }
              Console.WriteLine("HTTP/{0} {1} {2}", resp.ProtocolVersion, (int)resp.StatusCode, resp.StatusDescription);

  And my service is as follows :-      

   

  [ServiceContract]
  public interface IUploadService
  {
      [OperationContract]
      [WebInvoke(UriTemplate = "UploadFile/{fileName}")]
      void UploadFile(string fileName, Stream fileContent);  

  }

     public void UploadFile(string fileName, Stream fileContent)
      {
          using (StreamReader fileContentReader = new StreamReader(fileContent))
          {
              string content = fileContentReader.ReadToEnd();
              File.WriteAllText(Path.Combine(@"c:\temp", fileName), content);
          }
      }  
  
  
  

  However the response I am getting is :-

  The remote server returned an error: (400) Bad Request.

   

  Am I doing something wrong here?
