从HttpResponse中提取消息体

Okay, I've successfully connected to a remote server and received a HTTP/1.1 200 OK response and the response is packed into the HttpResponse object. Now how do I get the data in the response out of it, specifically the JSON that was sent from the server?

好的，我已成功连接到远程服务器并收到HTTP / 1.1 200 OK响应，并且响应被打包到HttpResponse对象中。现在我如何获取响应中的数据，特别是从服务器发送的JSON？

something like this: duplicate here : How do I parse JSON from a Java HTTPResponse?

像这样的东西：复制在这里：我如何解析Java HTTPResponse中的JSON？

HttpResponse response; // some response object
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
JSONTokener tokener = new JSONTokener(json);
JSONArray finalResult = new JSONArray(tokener);

Well, you can get the body of the HttpResponse by calling getEntity() which returns an object of type HttpEntity. You will then want to consume the InputStream that is returned from the getContent() method of the HttpEntity. I would do it like this:

好吧，你可以通过调用getEntity（）来获取HttpResponse的主体，它返回一个HttpEntity类型的对象。然后，您将需要使用从HttpEntity的getContent（）方法返回的InputStream。我会这样做：

public static String entityToString(HttpEntity entity) {
  InputStream is = entity.getContent();
  BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(is));
  StringBuilder str = new StringBuilder();

  String line = null;
  try {
    while ((line = bufferedReader.readLine()) != null) {
      str.append(line + "\n");
    }
  } catch (IOException e) {
    throw new RuntimeException(e);
  } finally {
    try {
      is.close();
    } catch (IOException e) {
      //tough luck...
    }
  }
  return str.toString();
}

You may also use EntityUtils

您也可以使用EntityUtils

response = cl.execute(p); //cl is http client and p is the post request

if(response.getStatusLine().getStatusCode()==200)
{
    try
    {
        String resp_body = EntityUtils.toString(response.getEntity());
        Log.v("resp_body", resp_body.toString());
        JSONObject jsobj = new JSONObject(resp_body);
    }
    catch(Exception e)
    {

       Log.e("sometag",e.getMessage());
     }
}

PS : You may have to do this in a separate thread, other than the main thread, like in the doInBackground() of an AsyncTask or Network operation on main thread exception may occur.

PS：您可能必须在除主线程之外的单独线程中执行此操作，例如在AsyncTask的doInBackground（）中，或者可能发生主线程异常上的网络操作。

Use a BasicResponseHandler when calling httpclient.execute()

调用httpclient.execute（）时使用BasicResponseHandler

ResponseHandler <String> resonseHandler = new BasicResponseHandler();
String response = httpclient.execute(httpget, resonseHandler);
