ASP.NET Core API / Angular-身份验证问题

因此，我目前正在进行一个我想做的项目，基本上是一个食品商店项目。问题是我有用户会将产品添加到他/她的购物车中并购买。我还有一个管理员，它将添加/删除/更改产品/用户。所以最主要的是，当我在邮递员中测试API时-它没有问题，我认为问题出在前端，因为当我在google中打开控制台时，它显示401错误。这是我的拦截器和警卫的代码。并且还使用角色（用户/管理员）进行身份验证。

拦截器：

import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Injectable } from "@angular/core";
import { Router } from '@angular/router';
import { Observable } from 'rxjs';
import { tap } from 'rxjs/operators';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

    constructor(private router: Router) { }

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        if (localStorage.getItem('token') !== null) {
            let request = req.clone({
                headers: req.headers.set('Authorization', 'Bearer ' + localStorage.getItem('token'))
            })

            return next.handle(request).pipe(
                tap(
                    success => { },
                    error => {
                        if (error.status == 401) {
                            localStorage.clear()
                            this.router.navigateByUrl('/home')
                        } else {
                            localStorage.setItem('error', error)
                        }
                    }
                )
            )
        } else {
            return next.handle(req.clone())
        }
    }
}

守卫：

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

@Injectable({
  providedIn: 'root'
})
export class AuthGuard implements CanActivate {

  constructor(private router: Router) { }

  canActivate(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean | UrlTree> | Promise<boolean | UrlTree> | boolean | UrlTree {
    if (localStorage.getItem('token') !== null) {
      return true
    } else {
      this.router.navigateByUrl('/home')
      return false
    }
  }

}
