                }
            ]
        }
    ]
}

我正在尝试保存RolePermisions，然后将每个权限保存到本地存储，但是我不确定如何执行此操作。最好是我想在ngOnInit（）里面做

TypeScript

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'app-dashboard',
  templateUrl: './dashboard.component.html',
  styleUrls: ['./dashboard.component.scss']
})
export class DashboardComponent implements OnInit {

  constructor( private activatedRoute: ActivatedRoute,) { }
  access_token = null;

  
  ngOnInit() {
    this.access_token = localStorage.getItem('access_token');
  }

}

我希望能够存储access_token以及RolePermision和每个权限

Answer 1

您是否只想保存RolePermissions而不是UserRoles，因为用户将只有一个角色？因为如果您要存储多个角色，则应该存储UserRoles。无论如何，仅存储RolePermissions并假设您始终拥有一个，并且上述对象存储在名为userdata的变量中，即：

localStorage.RolePermissions = JSON.stringify(userdata.UserRoles[0].RolePermissions);

要检索它，您将执行以下操作：

var permissions = JSON.parse(localStorage.RolePermissions);

Answer 2

存储到localStorage时，需要将数据存储为字符串（因此将权限数据转换为字符串。），并且从localStorage加载数据时，需要将该字符串转换为数组值。

如何将JSON数组存储到本地存储
