登录成功或失败后在环回框架中的重定向 [英] Redirection after the login succeeds or fails in loopback framework

问题描述

我最近开始使用环回框架，并通过创建一个继承自基本用户"的客户"模型来实现简单的登录功能:

I have recently started with loopback framework and made a simple login functionality by creating a 'customer' model inheriting from base 'User' like this:

CUSTOMER.JSON

CUSTOMER.JSON

{
    "name": "customer",
    "base": "User",
    "idInjection": true,
    "properties": {
        "email":{
            "type":"string",
            "required":false
        },
        "username":{
            "type":"string",
            "required":false
        }

    },
    "validations": [],
    "relations": {},
    "acls": [],
    "methods": []
}

CUSTOMER.JS

CUSTOMER.JS

module.exports = function(customer){

  }

然后我像这样在model-config.json中输入一个条目:

I then made a entry in model-config.json like this:

"customer": {
        "dataSource": "mango-database",
        "public": true
    }

是的，我能够轻松登录和注销.我有一个登录屏幕，其中包含用户名和密码.我将此表格提交给客户/登录，并在获得登录名后立即得到一个屏幕:

And yes I was able to login and logout easily. I have a login screen with fields username and password. I submit this form to customers/login and as soon as it gets the login, I get a screen:

{
id: "lvrTjKBKXCFPTMFej6AyegQUFYe5mSc1BiYbROZwCBM0jqae7kZ7v8ZfGujfDGgy",
ttl: 1209600,
created: "2014-12-07T08:12:17.572Z",
userId: "5483e88b5e9cf2fe0c64dd6c"
}

现在，我希望代替该屏幕，我应该能够将用户重定向到其他页面(仪表板)，并且如果登录失败，则应该返回到登录屏幕.

Now I want that instead of this screen, I should be able to redirect user to some other page (dashboard) and if the login fails, it should go back to the login screen.

我对此进行了很多搜索，发现的所有建议都是使用钩子的建议.但是钩子没有这样的事件.我在哪里编写重定向功能?我的猜测是CUSTOMER.JS

I googled up a lot on this and all i found was the suggestions to use hooks. But hooks doesn't have such event. Where do I write the redirection functionality? My guess is CUSTOMER.JS

我发现文档令人困惑！

推荐答案

使用远程挂钩中提供的context.res.例如:

Use context.res provided in a remote hook. For example:

Customer.afterRemote('create', function(context, customer, next) {
  var res = context.res; //this is the same response object you get in Express
  res.send('hello world');
})

基本上，您可以访问请求和响应对象，因此只需像在Express中一样进行响应即可.有关更多信息，请参见 http://expressjs.com/4x/api.html .

Basically, you have access to request and response objects, so just respond as you would in Express. See http://expressjs.com/4x/api.html for more info.
