我正在我的角度應(yīng)用程序中處理登錄和主頁組件。登錄服務(wù)正在驗證用戶的用戶名和密碼。成功登錄后，它應(yīng)該將用戶重定向到主頁。但是路由器重定向無法正常工作。登錄組件import { Router } from '@angular/router';import { Component, OnInit } from '@angular/core';import { FormControl, FormGroup, Validators } from '@angular/forms';import { User } from 'src/app/shared/models/user';import { AuthService } from '../services/auth.service';@Component({  selector: 'app-login',  templateUrl: './login.component.html'})export class LoginComponent implements OnInit {  userName: FormControl;  password: FormControl;  loginFormGroup: FormGroup;  loginError: boolean;  errorMessage: string;  messageString: string;  constructor(private router: Router, private authService: AuthService) { }  ngOnInit() {    this.userName = new FormControl("", [Validators.required]);    this.password = new FormControl("", [Validators.required]);    this.loginFormGroup = new FormGroup({      userName: this.userName,      password: this.password    });  }  login() {    this.loginError = false;    if (this.loginFormGroup.valid) {      let user: User = new User();      user.userId = this.userName.value;      user.password = this.password.value;      this.authService.login(user)        .subscribe(res =>         {          console.log(res)          this.router.navigate(["home"])          console.log("res")        },        error =>        {          console.log(error)        });    }  }}和登錄服務(wù)import { Injectable } from "@angular/core";import { Router } from "@angular/router";import { Observable } from "rxjs";import { share } from "rxjs/operators";import { environment} from 'src/environments/environment';import { HttpClient, HttpParams, HttpHeaders} from "@angular/common/http";import { User } from 'src/app/shared/models/user';@Injectable({ providedIn: "root" })export class AuthService {  user: User;  resp=401;  get userDetail(): User {    return this.user;  }  constructor(    private router: Router,    private http: HttpClient  ) {  }
