Access-Control-Allow-Headers不允许请求标头字段access-control-allow-origin，我发布http请求时收到此错误

Question

每当我请求使用Google API https://maps.googleapis.com/maps/api/geocode/

时

我收到此错误

我已经在7号角尝试过了

getHeaderOption(): any {
    return { headers: new HttpHeaders({
        'Content-Type': 'application/json',
        Authorization: 'Bearer ' + this.authService.getToken(),
        'Access-Control-Allow-Origin': '*'

      })};
  }



getPostalCode(address: string) {
    this.data = {
      address,
    };

    return this.http.post(environment.mapGeocodeUrl + 'json?address=' + address + '&key=' + environment.mapApiKey,
      this.data, this.getHeaderOption()).pipe(catchError(this.handleError));
  }

这需要响应结果，但会给出访问控制错误
