在Angular中动态添加客户端角色

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, UrlTree } from '@angular/router';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class RoleGuard implements CanActivate {
  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean | UrlTree> | Promise<boolean | UrlTree> | boolean | UrlTree {
    // 在这里进行角色验证逻辑，根据条件返回true或false
    // 例如，可以根据用户的权限信息判断是否具有某个角色
    const hasRole = // 判断用户是否具有某个角色的逻辑
    return hasRole;
  }
}

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home.component';
import { AdminComponent } from './admin.component';
import { RoleGuard } from './role.guard';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'admin', component: AdminComponent, canActivate: [RoleGuard] }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }
