因开发插件需要，将另一个网站的数据通过AJAX添加到ThinkPHP制作 的一个网站上的购物车。
需要网站支持跨域请求同步COOKE，具体操作如下：
/public/index.php
第二行添加以下代码：

$cookie .= “; SameSite=None”;
KaTeX parse error: Expected '}', got 'EOF' at end of input: …("Set-Cookie: {cookie}");
即可。
注意事项：
跨域Cookie要求带SameSite=None; Secure
而Secure属性要求当前页面必须是HTTPS
所以在HTTP下发送带Secure参数的Cookie会被浏览器忽略
导致不是https时登录或语言切换设置Cookie无法记录
而在https下切换语言和登录会正常.
解决方案：
在以下文件添加代码
/application/当前模板名/index/view/common/meta.html
