Android Volley：意外的响应代码405

My Android Volley JsonObjectRequest runs into onErrorResponse with the issue:

我的Android Volley JsonObjectRequest遇到问题时遇到onErrorResponse:

BasicNetwork.performRequest: Unexpected response code 405 for MY_URL

My URL is valid. I have checked that with a browser and I get there the expected JSON Object. So the issue has to be on the client side.

我的网址有效。我用浏览器检查了一下,然后我就到达了预期的JSON对象。所以问题必须在客户端。

The code 405 means:

代码405表示:

Method Not Allowed The method specified in the Request-Line is not allowed for the resource identified by the Request-URI. The response MUST include an Allow header containing a list of valid methods for the requested resource.

方法不允许请求行中指定的方法不允许由Request-URI标识的资源。响应必须包含一个Allow标头,其中包含所请求资源的有效方法列表。

my code for JsonObjectRequest:

我的JsonObjectRequest代码:

JsonObjectRequest jsonReq;
            jsonReq = new JsonObjectRequest(URL_FEED, new JSONObject(),
                    new Response.Listener<JSONObject>() {
                        @Override
                        public void onResponse(JSONObject response) {
                            try {
                                VolleyLog.v("Response:%n %s", response.toString(4));
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                        }
                    }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    VolleyLog.v("ERROR:%n %s", error.getMessage());
                }
            });

            // Adding request to volley request queue
            NetworkController.getInstance().addToRequestQueue(jsonReq);

Do I have to add some information to the header? And if what for information?

我是否必须在标题中添加一些信息?如果有什么信息?

The issue was that the request was set to POST by default. The solution that worked for me:

问题是默认情况下请求设置为POST。对我有用的解决方案:

  JsonObjectRequest jsonReq = new JsonObjectRequest
                            (Request.Method.GET, URL_FEED, null, new Response.Listener<JSONObject>()
                            {
                                @Override
                                public void onResponse(JSONObject response)
                                {
                                    Log.d("Server", "Läuft");
                                }
                            },
                                    new Response.ErrorListener()
                                    {
                                        @Override
                                        public void onErrorResponse(VolleyError error)
                                        {
                                            Log.d("Server","onErrorResponse");
                                        }
                                    });
                    NetworkController.getInstance().addToRequestQueue(jsonReq);

Use GET Method instead of POST it has worked for me.

使用GET方法而不是POST它对我有用。
