StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
    @Override

推荐答案

使用getBody代替getParams可以正常工作.由于您使用的是POST方法，因此应添加Request正文.

Use getBody instead of getParams it will work. Since you are using POST method you should add Request body.

       @Override
        public byte[] getBody() throws AuthFailureError {
            try {                    
                return stringRequestBody.getBytes("utf-8"); //String Request Body with Encoded
            } catch (UnsupportedEncodingException uee) {
                return null;
            }
        }
