How to Android http post to Node.js

Question

I want to send a simple HTTP POST request from Android to a Node.js server. Can anyone tell me what I'm doing wrong?

Android code:

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://54.68.139.250/bscreateuser");

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("username", "hellomoto"));
        nameValuePairs.add(new BasicNameValuePair("password", "pswd"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

Node.js code:

app.get('/bscreateuser', function(request, response) {
  process.stdout.write("Attempted to create a user.");
  bscreateUser(request.query.username, request.query.password);
  response.send('-- BS -- User Created! username: ' + request.query.username +
    ' password: ' +
    request.query.password);
});

function bscreateUser(username, password) {
  messageBody = 'create_user("' + username + '","' + password + '")';
  queueUrl = DAO_QUEUE_URL;
  // sys.puts("--- going for BS ---");
  sendSQSMessage(JSON.stringify(messageBody), queueUrl);
}

It appears that some people were able to answer your question without very much detail. In the future though, please include a detailed description of the behavior you're observing, rather than just describing what you're trying to do. Descriptions of undesired behavior are usually necessary to be able to help you. — skrrgwasme

I agree with @skrrgwasme. The question does not post the exact error that occurs. The answers were based on the most obvious mistake on the server side code that you have provided. — bluefog

In the node.js code, you are using

app.get('/bscreateuser', ...

Instead, you need to use the post method

app.post('/bscreateuser', ...

And access the requested variables like this :

request.body.varname

You make route of GET it must has to be post if you are posting data

node Code

app.post(..

and parameter may get

request.body.username or request.body.password
