Here is my call

URL url = new URL("http://www.server.com/api/v1");
            String query = "api_key=q5EicSKs027cjut7qhZk&method";

            //make connection
            URLConnection urlc = url.openConnection();

            //use post mode
            urlc.setDoOutput(true);
            urlc.setAllowUserInteraction(false);

            //send query
            PrintStream ps = new PrintStream(urlc.getOutputStream());
            ps.print(query);
            ps.close();

            //get result
            BufferedReader br = new BufferedReader(new InputStreamReader(urlc
                .getInputStream()));
            String l = null;
            while ((l=br.readLine())!=null) {
                System.out.println(l);
            }
            br.close();

Answer 1

You need to set Accept header.

urlc.addRequestProperty("Accept","application/json");

Update

Your server may not support application/json datatype. You can check it by curl .

curl -X POST  -H "Accept: application/json" --data 'api_key=q5EicSKs027cjut7qhZk&method' http://www.server.com/api/v1

Answer 2

Can you try something like below using Apache HTTP client ?

        HttpClient client = new DefaultHttpClient();

        HttpPost post = new HttpPost("http://www.server.com/api/v1");

        post.setHeader("api_key", "q5EicSKs027cjut7qhZk&method");

        HttpResponse response = client.execute(post);

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

        StringBuffer result = new StringBuffer();
        String line = "";
        while ((line = rd.readLine()) != null) {
            result.append(line);
        }

        JSONObject o = new JSONObject(result.toString());
