Apache Httppost从服务器Java检索图像

Question

Right now I am using Httppost to Post some parameters in the form of xml to a server. When the post occurs, a geotiff or .tif file is downloaded. I have successfully posted the document to the server and successfully downloaded the file simply by attaching the parameters to the url but I can't seem to combine the two. I have to use post because just using the URL leaves out elevation data in the geotiff.

In short, I am not sure how to simultaneously post and retrieve the image of the post. This is what I have thus far...

// Get target URL
        String strURL = POST;

        // Get file to be posted
        String strXMLFilename = XML_PATH;
        File input = new File(strXMLFilename);

        // Prepare HTTP post
        HttpPost post = new HttpPost(strURL);

        post.setEntity(new InputStreamEntity(
                new FileInputStream(input), input.length()));

        // Specify content type and encoding
        post.setHeader(
                "Content-type", "text/xml");

        // Get HTTP client
        HttpClient httpclient = new DefaultHttpClient();

        //Locate file to store data in
        FileEntity entity = new FileEntity(newTiffFile, ContentType.create("image/geotiff"));

        post.setEntity(entity);

        // Execute request
        try {
            System.out.println("Connecting to Metoc site...\n");

            HttpResponse result = httpclient.execute(post);

I was under the impression that the entity would contain the resulting image. Any help is much appreciated!

Thanks for the help guys. The entity was what was being sent to the server. I had code that was trying to read it from the response as well but it wasn't working because setting the entity to a file entity messed up the post request. By removing that part, it works great!
