Android 截击向服务器发送状态为 200 的空请求

Question

花费不眠之夜试图成功 post 此数据到我的服务器，但它返回错误，它在 postman 中工作正常，问题是它正在发送一个空请求到服务器。 Link 到服务器脚本。伙计们请帮我解决错误。这是 postman 请求和响应的屏幕截图。

Answer 1

尝试发送 JsonObjectRequest 而不是 StringRequest。

JsonObjectRequest request_json = new JsonObjectRequest(Request.Method.POST,url,object,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        Log.i("info", response.toString());
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.e("Error: ", error.getMessage());
            }
        });

Answer 2

我已经解决了我的问题，这是一个问题，只是在 header 中添加了主机，整个问题都解决了，因此将数据保存在我的数据库中。

       @Override
                            public Map<String, String> getHeaders() throws AuthFailureError {
                                HashMap<String, String> headers = new HashMap<String, String>();
                                headers.put("Content-Type", "application/json; charset=utf-8");
                                headers.put("Host", "localhost:8080");

                        
                                return headers;
                            }
