Android 有人能告诉我如何在指定的URL中读取这个JSON吗

我一直在阅读这个URL中的json文件。我在网上尝试了很多例子，但它无法读取这个URL中的特定json文件

[https://203.177.52.163:1985/restgateway/services/ws_download/Book/3372/Plant/03/User/12334]. Please help me what is wrong with this. Thank you for your help.

//这是我的代码示例

package com.hmkcode.android; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import org.apache.http.HttpResponse; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.DefaultHttpClient; import android.net.ConnectivityManager; import android.net.NetworkInfo; import android.os.AsyncTask; import android.os.Bundle; import android.util.Log; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; import android.app.Activity; public class MainActivity extends Activity { EditText etResponse; TextView tvIsConnected; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // get reference to the views etResponse = (EditText) findViewById(R.id.etResponse); tvIsConnected = (TextView) findViewById(R.id.tvIsConnected); // check if you are connected or not if(isConnected()){ tvIsConnected.setBackgroundColor(0xFF00CC00); tvIsConnected.setText("You are conncted"); } else{ tvIsConnected.setText("You are NOT conncted"); } // call AsynTask to perform network operation on separate thread //new HttpAsyncTask().execute("http://hmkcode.appspot.com/rest/controller /get.json"); new HttpAsyncTask().execute("https://203.177.52.163:1985/restgateway/services/ws_download/Book/3372/Plant/03/User/12334"); } public static String GET(String url){ InputStream inputStream = null; String result = ""; try { // create HttpClient HttpClient httpclient = new DefaultHttpClient(); // make GET request to the given URL HttpResponse httpResponse = httpclient.execute(new HttpGet(url)); // receive response as inputStream inputStream = httpResponse.getEntity().getContent(); // convert inputstream to string if(inputStream != null) result = convertInputStreamToString(inputStream); else result = "Did not work!"; } catch (Exception e) { Log.d("InputStream", e.getLocalizedMessage()); } return result; } private static String convertInputStreamToString(InputStream inputStream) throws IOException{ BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream)); String line = ""; String result = ""; while((line = bufferedReader.readLine()) != null) result += line; inputStream.close(); return result; } public boolean isConnected(){ ConnectivityManager connMgr = (ConnectivityManager) getSystemService(Activity.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); if (networkInfo != null && networkInfo.isConnected()) return true; else return false; } private class HttpAsyncTask extends AsyncTask { @Override protected String doInBackground(String... urls) { return GET(urls[0]); } // onPostExecute displays the results of the AsyncTask. @Override protected void onPostExecute(String result) {enter code here Toast.makeText(getBaseContext(), "Received!", Toast.LENGTH_LONG).show(); etResponse.setText(result); } } } 但是如果我把它改成这个url

new HttpAsyncTask().execute("https://203.177.52.163:1985/restgateway/services/ws_download/Book/3372/Plant/03/User/12334");

伙计们，我想知道这是不是服务器问题？或者这只是这个代码的一个错误。提前感谢。

我猜您正在尝试连接到自签名的HTTPS网站。这意味着您的证书不“正确”（由知名公司认证）。因此，android可能会阻止这个请求，比如说“SSL对等证书不正确”之类的话

如果我的猜测是正确的，我会把你们引向这个问题：这个被接受的答案对我来说似乎非常正确

试试看，如果有用的话告诉我

你试过吗？Android阅读JSON的例子不胜枚举。。您在获取json响应或解析json响应方面遇到了困难？请解释一下。。你完全正确。。。我已经成功了。然后我鼓励你接受答案，这样如果有人提出类似的问题，对他来说会更容易；）

new HttpAsyncTask().execute("http://hmkcode.appspot.com/rest/controller  /get.json");

new HttpAsyncTask().execute("https://203.177.52.163:1985/restgateway/services/ws_download/Book/3372/Plant/03/User/12334");
