如何从 JSON 获取数据 - 不推荐使用 HttpClient [重复]

Question

我曾经从下面的代码中获取 JSON 数据，但现在 HttpClient 已弃用，我不能再这样做了。你能帮帮我吗？

String responseString = null;
    try {
        HttpClient client = new DefaultHttpClient();
        URI apiCall = new URI("...");
        HttpGet request = new HttpGet();
        request.setURI(apiCall);
        HttpResponse response = client.execute(request);
        responseString = EntityUtils.toString(response.getEntity());
    } catch (Exception e) {
        Log.e("TAG", "some sort of problem encountered", e);
    }

使用另一个类，如

   URL url = new URL("http://www.android.com/");
   HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
   try {
     InputStream in = new BufferedInputStream(urlConnection.getInputStream());
     readStream(in);
    finally {
     urlConnection.disconnect();
   }
 }
