我是 angular/ionic 的新手，我被分配了一個專案，即使在用戶關閉應用程式后也應該登錄，除非注銷。誰能建議我如何修改以下代碼？

平臺準備好后，在你的 app.component.ts 中添加
if(this.authenticationService.isAuthenticated())
{
//Navigate to Home Page
}
else{
//Navigate to Login Page
}

首先，您的代碼太長，無濟于事，但我可以解釋您必須做的概念是，當您成功登錄時，您必須獲得令牌并存盤它。在應用程式打開后，您必須檢查存盤的令牌。如果該令牌仍然可用，您可以導航到主螢屏。否則你必須導航到你的登錄頁面。
login() {
const attempt = login(username,pw)
if(attempt.status === 200) {
//if username and pw is correct web service must be return token
this.storage.set("token", attempt.token)
navigate("where u want")
} else {
//Error when username or pw wrong.
}
如果您使用 ionic，您必須在 app.component.ts 中檢查您的令牌
const token = await this.storage.get("token")
const checkTokenIsAvailable = await checkToken(token)
if(checkTokenIsAvailable) {
navigate("where u want")
//Token is still available
} else {
navigate("login screen")
}
就這樣。
uj5u.com熱心網友回復：
所以我能夠用 subscribe() 方法解決這個問題。在 platfrom.ready 里面我叫這個
this.authService.authenticationState.subscribe((state) => {
if (state) {
this.navCtrl.navigateRoot("/tabs/tabs/home");
} else {
this.navCtrl.navigateRoot("");
}
});
