排序中带有嵌套参数的自定义POST请求返回意外响应代码422

Question

我有一个自定义的GSON请求，我只想在请求中添加嵌套的params。我尝试了不同的方法，但它没有工作，意外的响应代码422，我不知道我做错了什么。我在这里添加我的代码。

自定义请求类

 public CommunicationRequest(int method, String url, Class<T> clazz,    Map<String, String> headers,
                            Response.Listener<T> listener, Response.ErrorListener errorListener, JSONObject json) {
    super(method, url, errorListener);
    this.clazz = clazz;
    this.listener = listener;
    this.headers = headers;
    this.json = json;
}

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    return headers != null ? headers : super.getHeaders();
}

@Override
protected Response<T> parseNetworkResponse(NetworkResponse response) {
    try {
        String json = new String(
                response.data,
                HttpHeaderParser.parseCharset(response.headers));
        return Response.success(
                gson.fromJson(json, clazz),
                HttpHeaderParser.parseCacheHeaders(response));
    } catch (UnsupportedEncodingException e) {
        return Response.error(new ParseError(e));
    } catch (JsonSyntaxException e) {
        return Response.error(new ParseError(e));
    }
}



@Override
protected void deliverResponse(T response) {
    listener.onResponse(response);
}

@Override
public byte[] getBody() throws AuthFailureError {
    return json == null ? super.getBody() : json.toString().getBytes();
}

JSON格式

{"client_id":  "",
 "client_secret": "",
 "user":{
 "email": "test123@gmail.com",
 "password": "12345678",
 "password_confirmation": "12345678", 
 "first_name": "Test",
 "last_name": "Last",
 "mobile_phones_attributes": [
    {
      "number": "1234567890",
      "type": "Mobile"
    }
]
}   
}

请求格式

CommunicationRequest<DataObject> request = new CommunicationRequest<DataObject>(Request.Method.POST,
                uri,
                EmailValidObject.class, headers, this, this,params) ;

我正在以json格式制作JSONObject并将其传递给请求。

JSONObject params = new JSONObject();
    JSONObject user = new JSONObject();
    JSONObject mob = new JSONObject();
    JSONArray mob_att = new JSONArray();
    try {
        params.put("client_id", "some_client_id");
        params.put("client_secret", "some_client_secret");
          user.put("email", "testiunn@gmail.com");
          user.put("password", "12345678");
          user.put("password_confirmation", "12345678");
          user.put("first_name", "test first");
          user.put("last_name", "test last");
             mob.put("number", "+1 (123) 122-2123");
             mob.put("type", "Mobile");
             mob_att.put(mob);
          user.put("mobile_phones_attributes", mob_att);
        params.put("user", user);

    } catch (JSONException e) {
        e.printStackTrace();
    }
