  POST stream data in REST API-WCf

  Jan 05, 2013 01:34 AM|LINK

  Hi,

          I am working on a wcf rest api. I got issue to upload images from Client side to API. From Client side I do POST method to pass Streaming, and In Service, trying to fetch data through Message, StreamReader and some other ways also tried.

  I checked in debugging mode, stream has length of 15000 in Client Side, and when I recieve it in service, it is more than 15000, it is 21000.

  I am not getting any idea why some extra values are added in Stream.

  Please some one give idea to solve this issue.

  Thanks

  VD

  Check this article-

  Check this in your config file-

  maxStringContentLength

   and 

  maxBytesPerRead

  and make it to maximum for the testing purpost.

  Finally I got the solution.

  WCF REST API...

  public DealerImage PostImage(Stream sm)
           {
             System.Drawing.Bitmap imag = new System.Drawing.Bitmap(sm);
             byte[] imagedata = ImageToByte(imag);
              //Save byte code to database..
            
          }
  
         public static byte[] ImageToByte(System.Drawing.Image img)
          {
             
              ImageConverter converter = new ImageConverter();
              return (byte[])converter.ConvertTo(img, typeof(byte[]));
          }
  
  Client Code to POST image.......
  
   public void PostData()
      {
          try
          {
               byte[] fileToSend = null;
          string name = "";
          
          if (FileUpload1.HasFile)
          {
              name = FileUpload1.FileName;
              Stream stream = FileUpload1.FileContent;
              stream.Seek(0, SeekOrigin.Begin);
              fileToSend = new byte[stream.Length];
              int count = 0;
              while (count < stream.Length)
              {
                  fileToSend[count++] = Convert.ToByte(stream.ReadByte());
              }
              
          }
  
          HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("URL here");
        
          req.Method = "POST";
          req.ContentType = "application/octet-stream";
          req.ContentLength = fileToSend.Length;
          Stream reqStream = req.GetRequestStream();
          reqStream.Write(fileToSend, 0, fileToSend.Length);
          reqStream.Close();
  
          HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
  
          StreamReader reader = new StreamReader(resp.GetResponseStream());
  
          string result = reader.ReadToEnd();
          }
          catch (Exception ex)
          {
              
              throw ex;
          }
      }
