在我的应用程序(Angular 2 / Ionic 2)中,我实现了自己的登录/身份验证.基本上它的工作方式如下:在登录时,PHP后端正在验证用户名和密码.生成令牌,然后将其发送回标题中的前端(授权).后端的响应如下所示:
HTTP/1.1 200 OK Host: localhost:8080 Connection: close X-Powered-By: PHP/5.6.28 Set-Cookie: PHPSESSID=jagagi2le1b8i7r90esr4vmeo6; path=/ Expires: Thu,19 Nov 1981 08:52:00 GMT Cache-Control: no-store,no-cache,must-revalidate,post-check=0,pre-check=0 Pragma: no-cache Content-Type: application/json Authorization: d7b24a1643a61706975213306446aa4e4157d167eaad9aac989067a329c492d3 Access-Control-Allow-Origin: * Access-Control-Allow-Headers: X-Requested-With,Content-Type,Accept,Origin,Authorization Access-Control-Allow-Methods: GET,POST,PUT,DELETE,OPTIONS Content-Length: 301
显然有一个带有令牌的Authorization标头.
CORS似乎也可以正确设置,因为我在Allow-Headers标头中看到了Authorization.
但是,当我尝试在Angular 2中获取标头时,它总是返回null:
private extractDataAndSetAuthHeader(res: Response) { // Set auth header if available. // If not available - user is not logged in. Then // we also have to remove the token from localStorage if(res.headers.has("Authorization")) { let token = res.headers.get("Authorization"); this.setToken(token); } else { // If no token is sent,remove it this.removeToken(); } let body = res.json(); return body.data || { }; }
该方法的第一行返回false.此外,当我在我的回复中检查标题对象时,它仅显示以下内容(Chrome开发工具):
[[Entries]]: Array[4] 0:{"pragma" => Array[1]} 1:{"content-type" => Array[1]} 2:{"cache-control" => Array[1]} 3:{"expires" => Array[1]}
该对象中没有Authorization标头.
有人可以帮帮我吗?
提前致谢 :)
只是想发布答案,因为它可能会帮助其他人:

设定的解决方案
Access-Control-Expose-Headers: Authorization
然后 – 前端也可以读取Authorization标头.
