错误使用凌空库将数据发送到服务器 [英] error sending data to server using volley library

问题描述

我没有用凌空库了。我已阅读教程。我想将数据发送到一个URL这将在数据库中输入的数据。我曾尝试以下code，但它不工作。数据没有输入到数据库中。

I have not used volley library much. i have read the tutorials. i want to send data to a url which which will enter that data in database. i have tried the following code but its not working. data is not entered in the database.

  String url = "http://tipseducation.com/system/eadmin/insertschedule/";
        StringRequest sr = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                //Valid Response
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                //error message
            }
        }) {
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {

                Map<String, String> params = new HashMap<>();
                params.put("appt_name", ed_name);
                params.put("appt_email", ed_email);
                params.put("appt_contact", ed_contact);
                params.put("appt_date", ed_date);
                params.put("appt_time", ed_time);
                params.put("appt_service", ed_spinner);
                return params;
            }
        };

推荐答案

，你应该使用 getBody 你的POST请求。

您可以参考我下面的工作示例code（取代我的的JSONObject URL由你和）。希望这有助于！

You can refer to my following working sample code (replace my JSONObject and Url by yours). Hope this helps!

        ...   
        try {
            RequestQueue queue = Volley.newRequestQueue(this);
            jsonBody = new JSONObject();
            jsonBody.put("Title", "Android Volley POST DATA Demo");
            jsonBody.put("Author", "BNK");
            jsonBody.put("Date", "2015/09/17");
            requestBody = jsonBody.toString();

            StringRequest stringRequest = new StringRequest(1, url, new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    // do something...
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    // do something...
                }
            }) {
                @Override
                public String getBodyContentType() {
                    return "application/json; charset=utf-8";
                }

                @Override
                public byte[] getBody() throws AuthFailureError {
                    try {
                        return requestBody == null ? null : requestBody.getBytes("utf-8");
                    } catch (UnsupportedEncodingException uee) {
                        e.printStackTrace();
                        return null;
                    }
                }
            };
            queue.addToRequestQueue(stringRequest);
        } catch (JSONException e) {
            e.printStackTrace();
        }
        ...
