用JSON截击门柱-获得422状态码

Question

我试图使用Volley将JSON对象发送到使用MongoDB的环回应用程序API。我可以看到数据正在成功地保存在数据库中。但是凌空响应总是显示状态代码是422。有人能指出我做错了什么吗？

{
  "map_coordinates": {
    "lat": xxxxxx,
    "lng": xxxxxxx
  },
  "first_name": "xxxxx",
  "middle_name": "",
  "family_name": "xxxxxx",
  "gender": "xxxxxx",
  "role": "xxxxxx",
  "dob": "2017-09-28T05:51:40.836Z",
  "picture_of_person": "",
  "username": "[e-mail]",
  "deviceToken": "xxxxxxxx",
  "portal_address": "xxxxx",
  "email": "[e-mail]",
  "password": "xxxxxxx",
  "vcode": 562991,
  "mobile": "+91xxxxxxxx"
}

这是我用来发送JSON请求的代码。

public void postJsonRequest(String url, JSONObject data, final Callback<JSONObject, VolleyError> callback) {
    JsonObjectRequest objectRequest = new JsonObjectRequest(Request.Method.POST,
            url, data, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            callback.onSuccess(response);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            callback.onFailure(error);
        }
    });
    makeJsonRequest(objectRequest);
}

private void makeJsonRequest(JsonObjectRequest request) {
    RequestQueue queue = Volley.newRequestQueue(EngageMyTime.getInstance().getEMTContext());
    queue.add(request);
}

如有任何帮助/想法，将不胜感激。

尝试在服务器端设置默认的字符集UTF-8，并在发送之前用UTF-8对json数据进行编码

在android中

URLEncoder.encode(string,"UTF-8");
