如何在Angular 2中为openid令牌保留我的散列片段

import { Injectable } from '@angular/core';
import { Router } from '@angular/router';

@Injectable({
  providedIn: 'root'
})
export class AuthService {
  private fragment: string;

  constructor(private router: Router) {
    this.fragment = '';
  }

  setFragment(fragment: string): void {
    this.fragment = fragment;
  }

  getFragment(): string {
    return this.fragment;
  }

  redirectToFragment(): void {
    const url = this.router.serializeUrl(this.router.createUrlTree([], { fragment: this.fragment }));
    window.location.href = url;
  }
}

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
import { AuthService } from './auth.service';

@Component({
  selector: 'app-callback',
  template: '<div>Loading...</div>'
})
export class CallbackComponent implements OnInit {
  constructor(private route: ActivatedRoute, private authService: AuthService) {}

  ngOnInit(): void {
    this.route.fragment.subscribe(fragment => {
      this.authService.setFragment(fragment);
      this.authService.redirectToFragment();
    });
  }
}

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';
import { AuthService } from './auth/auth.service';
import { CallbackComponent } from './auth/callback.component';

const routes: Routes = [
  { path: 'callback', component: CallbackComponent }
];

@NgModule({
  declarations: [
    AppComponent,
    CallbackComponent
  ],
  imports: [
    BrowserModule,
    RouterModule.forRoot(routes)
  ],
  providers: [AuthService],
  bootstrap: [AppComponent]
})
export class AppModule { }

import { Component } from '@angular/core';
import { AuthService } from './auth/auth.service';

@Component({
  selector: 'app-root',
  template: `
    <button (click)="login()">Login</button>
  `
})
export class AppComponent {
  constructor(private authService: AuthService) {}

  login(): void {
    // 在此处执行OpenID登录流程，并获取散列片段
    const fragment = 'your_openid_token_fragment';

    this.authService.setFragment(fragment);
    this.authService.redirectToFragment();
  }
}
