java - 发送 HTTP POST - Android

Question

我知道有人问过这个问题，但大多数都已经过时，并且方法已被弃用。我找到了这个解决方案，

new Thread( new Runnable() {
        @Override
        public void run() {
            try {
                String query = "param=" +"item"+"&other="+"num";

                URL url = new URL("http://www.url.com/url_post.php");
                HttpURLConnection connection = (HttpURLConnection)url.openConnection();
                //Set to POST
                connection.setDoOutput(true);
                connection.setRequestMethod("POST");
                connection.setReadTimeout(10000);
                Writer writer = new OutputStreamWriter(connection.getOutputStream());
                writer.write(query);
                writer.flush();
                writer.close();


            } catch (Exception e) {
                // TODO Auto-generated catch block
                Log.e(TAG, e.toString());
            }
        }
    }).start();

但是，它没有提供如何获取返回的数据，例如，我返回一些 JSON，我从哪里获取返回的数据？

感谢您的帮助:)

Answer 1

这样做

 //Get Response 
  InputStream is = connection.getInputStream();
  BufferedReader rd = new BufferedReader(new InputStreamReader(is));
  String line;
  StringBuffer response = new StringBuffer(); 
  while((line = rd.readLine()) != null) {
    response.append(line);
    response.append('\r');

最后，在响应中，您将获得响应 JSON 字符串，然后执行您想做的操作。
