骨干model.save而服务器发送200返回错误：OK [英] Backbone model.save returning error while server sending 200:OK

问题描述

我已经定义了以下骨干型号：

I have defined the following Backbone Model:

var User = Backbone.Model.extend({
        url: "/login",
        contentType: "application/com.example.auth+json",

        defaults: {
            userName: '',
            password: ''
        },

        validate: function(attrs){
            if(!attrs.userName){
                return 'Please fill username field.'
            }
            if(!attrs.password){
                return 'Please fill password field.'
            }
        }
    });

我用下面的code在我Backbone.View

I am using the following code in my Backbone.View

// ... 
   initialize: function() {    
       this.model = new User();
       myUser = {
           userName: '[e-mail]',
           password: 'abcd_1234',
       };
    }

    onSubmit: function() {

        this.model.save(myUser, {
            success: function () {
                alert('You are authenticated');
                Backbone.trigger('Authenticated', {source: 'LOGIN'});
            },
            error: function (model, error) {
                alert('Error: " + error);
            }
        });
    }

我收到来自后端以下响应，没有任何反应的数据只发送状态$返回c $ C：

I am receiving the following response from backend, no response data is send only status code is returned:

Request URL : https://server/login

Request Method:POST

Status Code:200 OK

但我得到'错误：[对象的对象]'打印。为什么没有达到成功处理程序，服务器成功地验证用户inspite。请告知，如果需要如何在前端/后端解决这个问题。

But I am getting 'Error: [object Object]' printed. Why it is not reaching success handler, inspite of the server authenticating the user successfully. Please advise how to fix this in frontend / backend if required.

推荐答案

您可以使用此code 数据类型：文本来解决这个问题。

You can either use this code dataType: 'text' to fix it

...
this.model.save(myUser, {
    dataType: 'text',
    success: function () {
...

或正确的内容类型头设置为应用程序/ JSON 值。
