Meteor:如果已经登录，则重定向用户

Question

我正在使用 meteor-router ，我想将用户重定向到 /user如果他要求 /他已经登录了。
正如预期的那样，这只会呈现 user_index模板而不是更改 URL:

Meteor.Router.add
  '/': -> if Meteor.userId() then 'user_index' else 'index'

我想做这样的事情:

Meteor.Router.add
  '/': -> if Meteor.userId() then Meteor.Router.to '/user' else 'index'

这个问题不再相关， iron-router应该改用。

meteor 路由器现在是 deprecated .而是使用 iron-router可以使用以下方法根据登录状态重定向:

Router.configure({layoutTemplate: 'mainLayout'});

Router.map(function() {
  this.route('splash', {path: '/'});
  this.route('home');
});

var mustBeSignedIn = function(pause) {
  if (!(Meteor.user() || Meteor.loggingIn())) {
    Router.go('splash');
    pause();
  }
};

var goToDashboard = function(pause) {
  if (Meteor.user()) {
    Router.go('home');
    pause();
  }
};

Router.onBeforeAction(mustBeSignedIn, {except: ['splash']});
Router.onBeforeAction(goToDashboard, {only: ['splash']});

示例取自: Meteor.js - Check logged in status before render

使用 accounts-entry包裹。来自 their site :

Ensuring signed in users for routes

Use AccountsEntry.signInRequired(this) to require signed in users for a route. Stick that in your before hook function and it will redirect to sign in and stop any rendering. Accounts Entry also tracks where the user was trying to go and will route them back after sign in.
