在angularJS中的stateStateProvider上设置条件 [英] set condition on otherwise stateProvider in angularJS

问题描述

我正在研究一个项目，一旦用户输入了他的ID，他将无法在使用该应用程序时再次看到登录页面.

I am working on a project and it needs once a user entered his ID he wont be able to see the login page again when he will use the app.

我无法理解该怎么做，而我尝试过的这种逻辑是行不通的.

I am not able to understand how to do this logic which I had tried is not working.

有人可以帮我吗.这是我在Google云端硬盘上的项目链接，可以看看:

推荐答案

在这种情况下，您需要使用localStorage，一旦成功登录，将当前用户设置为true，而在注销时将该标志设置为false.

You need to use localStorage in this case, where once you successfully login set your current user to true and on logout set that flag to false.

在您的app.run块上，您可以设置条件.

and over your app.run block you can put a condition.

$rootScope.$on('$stateChangeStart', function (event, toState, toParams,fromState, fromParams) {
       if (toState.name !== 'login') {
            if (!localStorageService.get('currentUser') {
                event.preventDefault();
                $state.go('login');
            }
        } else {
            return false;
        }
}
