Angular2 http令牌

Question

如何获取令牌而不是json文件。 令牌由服务器在Header中从http get请求发送。

this.http.get('http://192.168.0.1:8080/DataBaseAccess/Connection', options).map(res => res.json()).subscribe(data => {
  console.log(data);
});


Response Headers (viewed in Chrome):

Access-Control-Allow-Headers:Origin, X-Requested-With, Content-Type, Accept
Access-Control-Allow-Methods:GET,POST
Access-Control-Allow-Origin:*
Content-Length:2
