How to print out returned message from HttpResponse?

Question

I have this code on my Android phone.

   URI uri = new URI(url);
   HttpPost post = new HttpPost(uri);
   HttpClient client = new DefaultHttpClient();
   HttpResponse response = client.execute(post);

I have a asp.net webform application that has in the page load this

 Response.Output.Write("It worked");

I want to grab this Response from the HttpReponse and print it out. How do I do this?

I tried response.getEntity().toString() but it just seems to print out the address in memory.

Thanks

Use ResponseHandler. One line of code. See here and here for sample Android projects using it.

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/user");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        ResponseHandler<String> responseHandler=new BasicResponseHandler();
        String responseBody = httpclient.execute(httppost, responseHandler);
        JSONObject response=new JSONObject(responseBody);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}

add combination of this post and complete HttpClient at - http://www.androidsnippets.org/snippets/36/

which android api version does this become available at? I might have to rewrite come code :D — , Apr 04 '10 at 00:26
I think it's been there since the beginning, or at least since Android 0.9. It's part of the standard HttpClient 4.x package. — CommonsWare, Apr 04 '10 at 00:32

I would just do it the old way. It's a more bulletproof than ResponseHandler, in case you get different content types in the response.

ByteArrayOutputStream outstream = new ByteArrayOutputStream();
response.getEntity().writeTo(outstream);
byte [] responseBody = outstream.toByteArray();

I used the following code

BufferedReader r = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

StringBuilder total = new StringBuilder();

String line = null;

while ((line = r.readLine()) != null) {
   total.append(line);
}
r.close();
return total.toString();

The simplest approach is probably using org.apache.http.util.EntityUtils:

String message = EntityUtils.toString(response.getEntity());

It reads the contents of an entity and returns it as a String. The content is converted using the character set from the entity (if any), failing that, "ISO-8859-1" is used.

If necessary, you can pass a default character set explicitly - e.g.

String message = EntityUtils.toString(response.getEntity(). "UTF-8");

It gets the entity content as a String, using the provided default character set if none is found in the entity. If the passed default character set is null, the default "ISO-8859-1" is used.

This code will return the entire response message in respond as a String, and status code in rsp, as an int.

respond = response.getStatusLine().getReasonPhrase();

rsp = response.getStatusLine().getStatusCode();`
