Javascript 是什么原因导致此Angular 16应用程序中类型错误时属性结果不存在

我一直在使用Angular 16、TypScript和电影数据库(TMDB)开发SPA.

在app\services\movie-service.service.ts中我有:

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import { environment } from '../../environments/environment';
import { HttpClient } from '@angular/common/http';
import { MovieResponse, Movie } from '../models/Movie';

@Injectable({
  providedIn: 'root'
})

export class MovieService {

  constructor(private http: HttpClient) { }

  public getMovies(): Observable<MovieResponse[]> {
    return this.http.get<MovieResponse[]>(`${environment.apiUrl}/movie/now_playing?api_key=${environment.apiKey}`);
  }
}

型号app\models\Movie.ts看起来是这样的:

export interface Movie {
    id?: number;
    adult?: boolean;
    backdrop_path?: string;
    poster_path?: string;
    title?: string;
    tagline?: string;
    overview?: string;
    genre_ids?: any;
    original_title?: string;
    release_date?: string;
    runtime?: number;
    vote_average?: string;
}

export interface MovieResponse {
    results?: Movie[];
    total_pages?: number;
    total_results?: number;
    page?: number;
}

在HomePageComponent中，我try 输出电影:

import { Component } from '@angular/core';
import { MovieResponse, Movie } from '../../models/Movie';
import { MovieService } from '../../services/movie-service.service';


@Component({
  selector: 'app-home-page',
  templateUrl: './home-page.component.html',
  styleUrls: ['./home-page.component.scss']
})
export class HomePageComponent {

  public movieResponse!: MovieResponse[];

  public movies: Movie[] = [];

  constructor(private movieService: MovieService) { }

  public getMovies() {
    this.movieService.getMovies().subscribe((response) => {
      this.movieResponse = response;

      console.log(this.movieResponse);

      this.movies = this.movieResponse.results;
    })
  }

  ngOnInit() {
    this.getMovies();
  }
}

行console.log(this.movieResponse)正确地显示带有results arary、total_pages等的响应;

问题

行this.movies = this.movieResponse.results导致错误:

TS2339: Property 'results' does not exist on type 'MovieResponse[]'.

Questions

1. 我做错了什么？
2. 解决此问题的最可靠方法是什么？
