Answer 1

當您登錄時創建一個cookie，本地存儲或會話存儲。遵守前面參考下面我

 this.services.checkUserDetails(this.userInfo.userId, this.userInfo.password).subscribe(
      data => { 
       if (data.status === true) { 
        localStorage.setItem('X-Auth-Token', data.data.token); //stored data in browser 
        console.log(data); 
        localStorage.setItem("userId", "1"); //stored data in browser 
} 
       else { 
        this.errorMessage = data.errorMessage; 
        this.utils.stopLoading(); 
       } 
      }, 
      error => { 
       this.errorMessage = error.errorMessage; 
       this.utils.toast("error", error); 
       this.utils.stopLoading(); 
      }); 

我的頭組件的代碼，我用這樣的

ngOnInit(): void { 
if (localStorage.getItem('X-Auth-Token') == null) { 
    this.router.navigate(['/login']); 
} 
else { 
    this.id = localStorage.getItem("userId");  //**Retried data** 
    this.name = localStorage.getItem("userName"); 
} 

}

用戶配置文件下拉列表創建包含用戶對象的全局服務

@Injectable() 
export class AuthService { 
    let user; 

    setUser(user) { this.user = user } 
    isLoggedIn() { return this.user } 
}
