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。基本上它是这样工作的:在登录时,PHP后端验证用户名和密码。生成一个令牌,将其发送回前端(Authorization标头)。后端的响应如下:
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
很明显有一个带有令牌的授权标头。由于我在Allow-Headers标头中看到了Authorization,因此CORS似乎也已经正确设置。
但是,当我试图在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,在检查响应中的headers对象时,仅显示以下内容(Chrome开发者工具):
[[Entries]]:
Array[4]
0:{"pragma" => Array[1]}
1:{"content-type" => Array[1]}
2:{"cache-control" => Array[1]}
3:{"expires" => Array[1]}
该对象中不存在授权标头。
有人可以帮忙吗?
提前致谢 :)
