问题描述
有人知道如何在不更改 url 的情况下更改 ui-router 状态吗?如下面的代码所示；在某些情况下，需要将用户重定向到 403 或 401 状态.我希望能够在不更改 url 的情况下执行此重定向.
Does anybody know how to change the ui-router state without changing the url? As the code below shows; in some cases the user needs to be redirected to 403 or 401 states. I would like to be able to do this redirect without changing the url.

// make sure authGetCurrent has ran before routing starts
$rootScope.$on("$locationChangeSuccess", function(event, next) {
event.preventDefault();
AuthService.loadCurrentAuth().then(function(){
$urlRouter.sync();
}, function(){
console.log("BIG ERROR!!!");
});
});
// Configures $urlRouter's listener *after* your custom listener
$urlRouter.listen();
$rootScope.$on("$stateChangeStart", function(event, toState, toParams, fromState, fromParams) {
var requiredLogin = (toState && toState.data ? toState.data.requiredLogin : false ),
requiredGroupRights = (toState && toState.data ? toState.data.requiredGroupRights : false ); // require the user to have at least one of these rights in the current group
if (requiredLogin && !AuthService.isLoggedIn()) {
event.preventDefault();
$state.transitionTo('401');
return;
}
if(requiredGroupRights){
var i,
hasRight = false;
for(i=0;i<requiredGroupRights.length;i++){
if(GroupService.checkGroupRights(toParams.groupId, requiredGroupRights[i])){
hasRight = true;
break;
}
}
if(!hasRight){
event.preventDefault();
$state.transitionTo('403');
return;
}
}
});
推荐答案
将 { location: false } 选项传递给 $state.go
Pass the { location: false } option to $state.go
$state.go("home.foo", {}, { location: false } );
查看实际操作:http://plnkr.co/edit/w2aolrt9wdW3EFcEB3Lw?p=preview
var app = angular.module('demonstrateissue', ['ui.router']);
app.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise("/home");
$stateProvider.state({
name: 'home',
url: '/home',
controller: function() { },
template: '<h1>Home</h1><div ui-view></div>'}
);
$stateProvider.state({
name: 'home.foo',
url: '/foo',
controller: function() { },
template: '<h1>foo</h1>'}
);
});
// Adds state change hooks; logs to console.
app.run(function($rootScope, $state, $location) {
$rootScope.$state = $state;
$rootScope.$location = $location;
// This function will go to home.foo state but not change url
$rootScope.gotofoo = function() {
$state.go("home.foo", {}, { location: false } );
};
});
