日期類型的參數不能分配給字符串類型的參數

Question

我正在學習Angular和.net課程。

我正在嘗試將photourl設置為方法。

我收到以下錯誤信息\\

日期類型的參數不能分配給字符串類型的參數

錯誤在下一行。

this.changeMemberPhoto（this.currentUser.photoUrl）;

爭論是問題

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { BehaviorSubject } from 'rxjs';
import { map } from 'rxjs/operators';
import { JwtHelperService} from '@auth0/angular-jwt';
import { environment } from 'src/environments/environment';
import { User } from '../_models/user';

@Injectable({
  providedIn: 'root'
})

export class AuthService {
  baseUrl = environment.apiUrl + 'auth/';
  jwtHelpter = new JwtHelperService();
  decodedToken: any;
  currentUser: User;
  photoUrl = new BehaviorSubject<string>('../../assets/user.png');
  currentPhotoUrl = this.photoUrl.asObservable();

  constructor(private http: HttpClient) {}


  changeMemberPhoto(photoUrl: string) {
    this.photoUrl.next(photoUrl);
  }

  login(model: any) {
    return this.http.post(this.baseUrl + 'login', model).pipe(
      map((response: any) => {
        const user = response;
        if (user) {
          localStorage.setItem('token', user.token);
          localStorage.setItem('user', JSON.stringify(user.user));
          this.decodedToken = this.jwtHelpter.decodeToken(user.token);
          this.currentUser = user.user;
          this.changeMemberPhoto(this.currentUser.photoUrl);
        }
      })
    );
  }

  register(model: any) {
    return this.http.post(this.baseUrl + 'register', model);
  }

  loggedIn() {
    const token = localStorage.getItem('token');
    return !this.jwtHelpter.isTokenExpired(token);
  }
}

代碼與講師相同，所以我不知道問題出在哪里。

我已按要求包含User類

import { Photo } from './photo';

export interface User {
    id: number;
    username: string;
    knownAs: string;
    age: number;
    gender: string;
    created: Date;
    lastActive: Date;
    photoUrl: Date;
    city: string;
    country: string;
    interests?: string;
    introduction?: string;
    lookingFor?: string;
    photos?: Photo[];
}

Answer 1

photoUrl是您課程中的日期，並且是您的changeMemberPhoto方法中的字符串

在用戶類中，將其更改為：

photoUrl: string;
