Angular 6：如何获取响应状态代码

Question

如何获取服务代码？我尝试下面的代码，但它没有记录任何内容。

在 service.ts 文件中。

constructor(private http: HttpClient) { }

postForgotPass(email): Observable<Response> {

return this.http.post<Response>(envi.apiUrl +'/user/forgotpassword', {
  "email": email,
  "headers": headers,
  observe: 'response'

})
}

在我的 component.ts 文件中

sendForgotPass() {
 return this.service.postForgotPass(this.emailFormControl.value)
    .subscribe(
      res => {
        console.log(res.status);
      })
    }

来自Angular 文档：

getConfigResponse(): Observable<HttpResponse<Config>> {
  return this.http.get<Config>(
    this.configUrl, { observe: 'response' });
}

用法

this.configService.getConfigResponse()
    // resp is of type `HttpResponse<Config>`
    .subscribe(resp => {
      // display its headers
      const keys = resp.headers.keys();
      this.headers = keys.map(key =>
        `${key}: ${resp.headers.get(key)}`);

      // access the body directly, which is typed as `Config`.
      this.config = { ... resp.body };
    });
