Json 愚蠢'；错误：尝试区分'；[对象对象]'；。只允许使用数组和iterables'；

我不能让这个工作，我知道我错过了一些愚蠢的。。。。不管我怎么做，我总是会遇到这样的错误：“错误错误：尝试区分'[object]'时出错。只允许使用数组和可重用项”我到底错过了什么。我知道这很愚蠢，但我在网上任何地方都找不到答案。无论我做什么尝试，我总是回到这个错误

服务代码：

  SearchByTitle(title: string) {
    const url = `${this.url}&s=${title}`;
    return this.http.get<Movies[]>(url)
    .pipe(
      retry(1),
      catchError(this.handleError)
    );
  }

您的服务返回带有movies数组和附加信息（如“totalResults”）的对象，您需要通过从响应对象获取“搜索”字段来获取movies数组。 所以只要改变

this.movieData = res;

到

在GetData函数中，请给出您从api收到的响应？检查响应。此外，在NGFORTH工作的

GetData（）{wait this.movieService.SearchByTitle（'star'）.subscribe（（res:any）=>{this.movieData=res['Search']；console.log（JSON.stringify（this.movieData））；}，error=>{console.log（“发生了意外错误”）；}；返回this.movieData；}

<div class="content">
    <button id="searchBtn" (click)="GetData">Search</button>
    <div class="movieList" *ngIf="movieData">
        <div class="movies" *ngFor="movie of movieData">
            <p class="movieTitle">Movies</p>
        </div>
    </div>
