req.user undefined for request from Android app to NodeJS server

Question

I am developing an Android app with a NodeJS backend server. I am having problems authenticating the users when requests are made to different pages after the user is logged in.

Once I log in, i store the set-cookie value in SharedPrefs. Now when I make a POST request, I am sending the set-cookie value in the header, i.e. con.setRequestProperty("set-cookie", cookie); for authenticating the user on the backend using req.user.authenticate.

However, req.user is undefined and hence the request fails. What could be wrong over here? Thanks.

Below is my POST request code.

    con = (HttpURLConnection) obj.openConnection();
    con.setRequestMethod("POST");
    con.setRequestProperty("User-Agent", "\"Mozilla/5.0\"");

    con.setDoOutput(true);

    JSONObject jsonParam = new JSONObject();
    try {
        jsonObject.accumulate("set-cookie", cookie);
    } catch (JSONException e) {
        e.printStackTrace();
    }

    OutputStreamWriter out = new   OutputStreamWriter(con.getOutputStream());
    out.write(jsonParam.toString());
    out.close();

    int responseCode = con.getResponseCode();
    System.out.println("Response Code:"+responseCode);

Send data in this format

 String data = "";

InputStream inputStream = null;


try{

    JSONObject jsonObject = new JSONObject();
    jsonObject.accumulate("set-cookie", cookie);


    data = jsonObject.toString();
    Log.d("json data",data);
    // 1. create HttpClient
    HttpClient httpclient = new DefaultHttpClient();

    // 2. make POST request to the given URL
    HttpPost httpPost = new HttpPost(CHECK_WEBSERVICE_URL);
    StringEntity se = new StringEntity(data);

    // 6. set httpPost Entity
    httpPost.setEntity(se);

    // 7. Set some headers to inform server about the type of the content
    httpPost.setHeader("Accept", "application/json");
    httpPost.setHeader("Content-type", "application/json");

    // 8. Execute POST request to the given URL
    HttpResponse httpResponse = httpclient.execute(httpPost);

    // 9. receive response as inputStream
    inputStream = httpResponse.getEntity().getContent();

    // 10. convert inputstream to string
    if(inputStream != null)
        result = convertInputStreamToString(inputStream);
    else
        result = "Did not work!";


    System.out.print(result);

}catch (Exception e){

    e.printStackTrace();
}

isn't DefaultHttpClient() deprecated? – user782400 Nov 04 '16 at 12:40
you use HttpURLConnection what important is to send data in json format. But before sending convert it into string – siddhesh Nov 04 '16 at 12:42
trying to make it work using HttpURLConnection. Having trouble with sending the JSON formatted data. – user782400 Nov 04 '16 at 12:56
