在谷歌调试中报错，并且直接屏蔽了服务器发送过来的cookie：
A cookie associated with a cross-site resource at http://cs.jius.net/ 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.

地址栏输入：chrome://flags/
搜索SameSite ，找到SameSite by default cookies、Cookies without SameSite must be secure，设置成 Disable
