Angular 8 HttpClient GET响应未返回自定义标头

Question

我试图在http请求后获取响应头，但我无法获取...

headers: HttpHeaders;
httpOptions;

  constructor(private http: HttpClient) {
    const token = localStorage.getItem("token");
    this.headers = new HttpHeaders({
      "Content-Type": "application/x-www-form-urlencoded"
    }).set("x-auth-token", token);

    this.httpOptions = {
    headers: this.headers,
    responseType: "text" as "json",
    observe: "response"
};}


test<T>(url: string) {
    return this.http.get<T>(url, this.httpOptions).pipe(
      tap((res: HttpResponse<any>) => {
        console.log(res.headers.keys())
      }))
  }

我正试图得到这个：header

看看这个：Get-Full-Response

我在这里尝试过此代码，并且可以正常工作：

    this.http.get(this.url, { observe: `response` })
    .subscribe((res) => {
      console.log(res);
    })

我使用了订阅而不是管道。 这是响应：

Response printed on console

我不确定这是否有帮助。
