I need to send a byte arrray file using WCF rest services. I have to send the data using HttpPost method in android. The code which i am using give the status as HTTP/1.1 400 Bad Request error.

  private final static String URI = "http://192.168.1.15/QueryService/Import/Test";
         final HttpPost request = new HttpPost(URI);
            final HttpClient httpClient = new DefaultHttpClient();
            final ByteArrayEntity entity = new ByteArrayEntity(fileToBytes(pathToOurFile));
            entity.setContentType("application/octet-stream");
            entity.setChunked(true);
            request.setEntity(entity);
            final HttpResponse hr = httpClient.execute(request);
           final StatusLine status = hr.getStatusLine();
        httpClient.getConnectionManager().shutdown();

I was also facing same problem with WCF service. 400 Bad request means request parameter value which you are passing to method doesn't match with method's parameter. I have used Base64 string encoding to pass file as method parameter. May it'll help you.

It is difficult to tell what is wrong with your request. The standard way of resolving this kind of errors is:

  • Create a WCF client for your service. Verify that it works as expected.
  • Use Fiddler or another suitable tool to intercept the HTTP request your client is generating. Both the headers and the body are important.
  • Modify your Android request to generate the exact same request as the WCF client.
