missing SameSite attribute

这个问题通常是出现在使用 cookie 的网站上，是因为浏览器最近更新了同源策略，并且需要在 cookie 中添加 SameSite 属性来指定 cookie 的安全性。

要解决这个问题，你可以在设置 cookie 时添加 SameSite 属性，例如：

Set-Cookie: mycookie=test; SameSite=None; Secure

其中，SameSite 属性可以有三个值：

- Strict：只允许同站点请求发送 cookie。
- Lax：允许一部分第三方站点发送 get 请求，但是对于 post、put 等请求无效。
- None：允许所有站点发送 cookie。

注意，使用 None 值时必须同时设置 Secure 属性，以确保 cookie 只能通过 HTTPS 连接发送。

Indicate whether to send a cookie in a cross-site request by specifying its SameSite attribute

Yes, you can indicate whether to send a cookie in a cross-site request by specifying its SameSite attribute. The SameSite attribute can have three values: "Strict", "Lax", or "None".

- "Strict" means that the cookie should only be sent in a first-party context, meaning that it should only be sent with requests originating from the same site that set the cookie.
- "Lax" is a less strict version of "Strict" that allows some exceptions, such as when a user follows a link from an external site.
- "None" means that the cookie can be sent in any context, including cross-site requests.

Setting the SameSite attribute to "Strict" or "Lax" can help prevent certain types of attacks, such as cross-site request forgery (CSRF). However, it's important to note that not all browsers support the SameSite attribute, so it should be used in conjunction with other security measures.
