角度2:无法访问http请求中的响应标头 [英] Angular 2: Can't access response headers in a http request

问题描述

我正在使用angular2-http(alpha.44)模块从REST Api中检索数据.我无法弄清楚如何访问响应的标题映射中的信息，我需要从中获取一个特定字段.示例:

I'm using angular2-http(alpha.44) module to retrieve data from a REST Api. I can't figure out how to access the information that comes in the headers map of the response, from which I need a specific field. Example:

var req = new Request({
  url: `localhost/api/products`,
  method: RequestMethods.Get
});

this.http.request(req).subscribe(
  res => {
    // Can't access the headers of the response here.... res.headers is empty
    },
  error => { ... },
  _ => {}
);

奇怪的是，如果我在浏览器的开发工具中检查网络流量，则会显示响应标头...

Strangely enough, if I check the network traffic in the browser's dev tools, the response headers are present...
