angular 的ui.router 定义不同的state 对应相同的url

Angular UI Router: Different states with same URL?

The landing page of my app has two states: home-public, home-logged-in. Now I want to show both states on the same URL, but let the controller and template depend on the user session (is the user logged in or not?).

Is there a way to achieve this?

You could have a base state that controls which state to load, and you could simply have the child stated of that base state not have urls:

.state('home', {
  url: "/home",
  templateUrl: "....",
  controller: function($scope,$state,authSvc) {
     if(authSvc.userIsLoggedIn()){
          $state.go('home.loggedin')
     }else{
          $state.go('home.public')
     }
  }
})


.state('home.public', {
  url: "",
  templateUrl: "....",
  controller: function($scope) {
     ...........
  }
})

.state('home.loggedin', {
  url: "",
  templateUrl: "....",
  controller: function($scope) {
     ...........
  }
})

Now in the controller of your base state (home) you can check if the user is logged in or not, and use $state.go() to load an appropriate state.
