而在Android上使用凌空服务器没有收到JSON对象 [英] Server does not receive JSON object while using volley on android

问题描述

我试图用凌空JSON对象发送到服务器，并得到回应，但似乎在服务器犯规获得数据。

I tried to use volley to send JSON object to server and get a response but it seems the server doesnt get the data.

如果我试图只是回显它的工作原理，但如果我尝试读取服务器上的JSON对象，并作出反应，我得到凌空错误。我也试着回显JSON对象，并仍然得到错误。
当我使用的Htt prequest一切工作正常。
我加了相同的标题，如在Htt的prequest和截击，也许连接到UTF8？这是我在做setEntity

If i tried to just echo back it works, but if i try to read the JSON object on server and react, i get error on volley. I also try to echo back the JSON object and still get error. When i use HttpRequest everything works ok. I added the same Headers as in HttpRequest and Volley, Maybe is connected to UTF8? which i do on setEntity

我得到关于PHP中的数据是这样的：

i get the data on PHP like this:

$data = json_decode(file_get_contents('php://input'), true);

我的凌空code：

My volley code:

JsonObjectRequest req = new JsonObjectRequest(Request.Method.POST,
           URL, jsonObject ,
           new Response.Listener<JSONObject>() {
               @Override
               public void onResponse(JSONObject response) {

                       Log.d(TAG,"Response: " + response.toString());

               }
           }, new Response.ErrorListener() {
               @Override
               public void onErrorResponse(VolleyError error) {
                   VolleyLog.e("Error: ", error.getMessage());
               }
           })
            {     
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError { 
                        Map<String, String>  params = new HashMap<String, String>();  
                        params.put("Accept", "application/json");  
                        params.put("Content-Type", "application/json");

                        return params;  
                }
            };
    ;

人有一个想法？

推荐答案

原来，我凌空code是确定的。问题是在服务器侧

It turned out that my volley code was ok. the problem was on the server side.

使用Breadbin评论和更换用error.printStackTrace（）的VolleyLog.e帮助查找问题。

Using Breadbin comment and replacing the VolleyLog.e with error.printStackTrace() helped to find the problem.
