Android: Uploading a file to a page along with other POST strings

Question

I am trying to upload an image to a PHP page along with some other info about the image so the PHP page knows what to do with it. Currently, I am getting away with it using this:

URL url = new URL("http://www.tagverse.us/upload.php?authcode="+WEB_ACCESS_CODE+"&description="+description+"&userid="+userId); HttpURLConnection connection = (HttpURLConnection)url.openConnection(); connection.setDoOutput(true); connection.setRequestMethod("POST"); OutputStream os = connection.getOutputStream(); InputStream is = mContext.getContentResolver().openInputStream(uri); BufferedInputStream bis = new BufferedInputStream(is); int totalBytes = bis.available(); for(int i = 0; i < totalBytes; i++) { os.write(bis.read()); } os.close(); BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); String serverResponse = ""; String response = ""; while((response = reader.readLine()) != null) { serverResponse = serverResponse + response; } reader.close(); bis.close();

Is there a more elegant solution to this besides having a GET/POST hybrid? I feel as if this is sloppy, but for all I know it is a perfectly acceptable solution. If there is a better way of doing this, I'd appreciate being pointed in the right direction. Thanks!

PS: I am familiar with how you would, under normal conditions, interact with a PHP page via POST:

HttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost("http://www.tagverse.us/login.php"); try { List<NameValuePair> pairs = new ArrayList<NameValuePair>(); pairs.add(new BasicNameValuePair("authcode", WEB_ACCESS_CODE)); pairs.add(new BasicNameValuePair("username", username)); pairs.add(new BasicNameValuePair("password", password)); post.setEntity(new UrlEncodedFormEntity(pairs)); client.execute(post); }

Essentially what I'd like to do is combine these two methods, but because I work with an HttpURLConnection object rather than a HttpPost object, it isn't as simple as just merging the two.

Thank you!

You can try an take a look at the answer I added for this similar question: https://stackoverflow.com/a/9003674/472747

Here is the code:

byte[] data = {10,10,10,10,10}; // better get this from a file or memory HttpClient httpClient = new DefaultHttpClient(); HttpPost postRequest = new HttpPost("server url"); ByteArrayBody bab = new ByteArrayBody(data, "image.jpg"); MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); reqEntity.addPart("image", bab); FormBodyPart bodyPart=new FormBodyPart("formVariableName", new StringBody("formValiableValue")); reqEntity.addPart(bodyPart); bodyPart=new FormBodyPart("formVariableName2", new StringBody("formValiableValue2")); reqEntity.addPart(bodyPart); bodyPart=new FormBodyPart("formVariableName3", new StringBody("formValiableValue3")); reqEntity.addPart(bodyPart); postRequest.setEntity(reqEntity); HttpResponse response = httpClient.execute(postRequest); BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); String line = null; while((line = in.readLine()) != null) { System.out.println(line); }
