HttpUrlConnection Get method returns status code 405

I am trying to fetch data from a server using HttpURLConnection

. The request is a request GET

. But it always returns a status code 405(BAD_METHOD)

. Below is the method I wrote:

URL url2 = new URL("http://www.example.com/api/client_list?");
HttpURLConnection connection = (HttpURLConnection) url2
                .openConnection();
connection.setRequestMethod("GET");
connection.setReadTimeout(NET_READ_TIMEOUT_MILLIS);
connection.setConnectTimeout(CONNECTION_TIMEOUT_MILLIS);
connection.setRequestProperty("Authorization", token);
connection.setDoInput(true);
connection.setDoOutput(true);

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("client_id", clientRole));

OutputStream os = connection.getOutputStream();
BufferedWriter writer = new BufferedWriter(
                new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(params));
writer.flush();
writer.close();
connection.connect();

      

        
        
        
      

    

GetQuery ()

private String getQuery(List<NameValuePair> params)
            throws UnsupportedEncodingException {
    StringBuilder result = new StringBuilder();
    boolean first = true;

    for (NameValuePair pair : params) {
        if (first)
            first = false;
        else
            result.append("&");

            result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
    }

    return result.toString();
}

      

        
        
        
      

    

If I HttpClient

do the same with use , I get the desired result. Following is the same operation withHttpClient

String url = "http://www.example.com/api/client_list?client_id=" + rolename;
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
httpGet.setHeader("Authorization", "Bearer " + token);
httpClient.execute(httpGet);

      

        
        
        
      

    

I don't understand what I am doing wrong with the HttpUrlConnection.
