无法从离子注销 [英] can't logout from ionic

问题描述

我遇到了 ionic 登录和注销的问题.

Hi I have an issue with ionic login and logout.

每次注销后，我仍然可以单击后退按钮，它会将我带回上一页.我可以知道如何在注销时清除或删除会话，以便用户无法从登录返回上一页吗?

Each time after logout, i can still click the back button and it will bring me back to my previous page. may i know how to clear or delete session when logout so that user unable to go back to previous page from the login?

var default_stat;
$scope.logout = function(){
    $ionicLoading.show({template:'Logging out....'});
    $localstorage.set('loggin_state', '');
    $state.go('login');
    $ionicLoading.hide();
    $ionicHistory.clearHistory();
    $ionicHistory.clearCache();
};

在登录时我使用 localstorage 来表示用户已经登录

during login i use localstorage to indicate user has logged in

$localstorage.set('loggin_state', '1');

推荐答案

我会这样做:

$scope.logout = function(){
    $ionicLoading.show({template:'Logging out....'});
    $localstorage.set('loggin_state', '');

    $timeout(function () {
        $ionicLoading.hide();
        $ionicHistory.clearCache();
        $ionicHistory.clearHistory();
        $ionicHistory.nextViewOptions({ disableBack: true, historyRoot: true });
        $state.go('login');
        }, 30);

};

我发现添加一点延迟可以让 $ionicHistory 清除缓存.

I've found out that adding a little delay allow $ionicHistory to clear the cache.

$ionicHistory.nextViewOptions({ disableBack: true, historyRoot: true });

• disableBack:下一个视图应该忘记它的后视图，并将其设置为空.
• historyRoot:下一个视图应该成为其历史堆栈中的根视图.
• disableBack: The next view should forget its back view, and set it to null.
• historyRoot: The next view should become the root view in its history stack.
