UI-Router 1.0基于用户角色重定向

I'm upgrading to ui-router@1.0.0-beta.2 and trying to figure out what is the best way to redirect user to a different state if he doesn't have necessary permissions.

我正在升级到ui-router@1.0.0-beta.2并尝试找出如果用户没有必要的权限,将用户重定向到其他状态的最佳方法。

This is what I have:

这就是我所拥有的:

.state('company_dashboard', {
    url: '/dashboard',
    templateUrl: 'dashboard.html',
    controller: 'CompanyDashboardCtrl',
    resolve: {
        user: function(UserService) {
            return UserService.getActiveUser();
        },
        company: function(UserService) {
            return CompanyService.getActiveCompany();
        },
        permissions: function(CompanyService, user, company){
            return CompanyService.getUserPermissions(company, user);
        }
    },
    onEnter: function($state, permissions) {
        if (permissions.canAccessDashboard === false)
            return $state.go('company_landing_page');
    }
})

The above example works, but it logs the following error: TransitionRejection(type: 2, message: The transition has been superseded by a different transition, detail: Transition#1( ''{} -> 'company_landing_page'{} )) which makes me think, there should be a better way.

上面的示例有效,但它记录了以下错误:TransitionRejection(类型:2,消息:转换已被不同的转换取代,详细信息:转换#1(''{} - >'company_landing_page'{}))让我想到,应该有一个更好的方法。

Side question, is it the good practice to check permissions during the resolve?

附带问题,在解决过程中检查权限是一种好习惯吗?

UPDATE:

Changing $state.go() to $state.target() helped me to get rid of the console error. This comment has helped. Though the question stands, whether I'm doing it it the right place?

将$ state.go()更改为$ state.target()帮助我摆脱了控制台错误。这条评论有所帮助。虽然问题在于,我是否正确地把它做到了正确的地方?

I would add a data property to your state as follows:

我会向您的州添加一个数据属性,如下所示:

.state('company_dashboard', {
    data: {
           requiresAuthentication: true
    }
}

And then:

app.run(function ($rootScope, $state) {
    $rootScope.$on('$stateChangeStart', function (event, toState, toParams) {
        // Check if user is authenticated
        // And route requires authentication
       if (!toState.data.requiresAuthentication) {
            $state.go(toState.name, toParams);
       } else if (user && toState.data.requiresAuthentication) {
            $state.go(toState.name, toParams);
       } else {
            $state.go('login');
       }
    });
});

This seems to work quite well even if I am sure it can be more polished, but I hope this gives you an idea on how you may proceed.

这似乎工作得很好,即使我确信它可以更加精致,但我希望这可以让你了解如何进行。
