Chrome 浏览使用IFRAME嵌套站点cookie传递失败

A cookie associated with a cross-site resource at http://XXX.XXX.XXX.XXXX/ was set without the `SameSite` attribute. 
It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. 

http {
	...
	map $http_user_agent $samesite_attr {
		"~*chrome"	';Secure;SameSite=None';
	}
	...
	server {
		location / {
			...			
			proxy_cookie_path ~/(.*) "/$1$samesite_attr";
        }
	}
}
