上面提示有baidu 想得通加了有百度统计，发现有提示360，打开application  查看cookies 发现有360统计后台去找才发现很早之前 百度和360 统计放在一起添加的

SameSite 属性

Cookie 的SameSite属性用来第三方 Cookie，从而减少安全风险。

有以下解决方案：

第一、在head头部加入

<?php header("Set-Cookie: key=value; path=/; domain=*.xxxx.com; Secure; SameSite=None"); ?>

第二、在cookie中追加属性 SameSite=None

在cookie中追加属性 SameSite=None

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

如果有加cdn 直接在服务商处

在响应头中设置 Set-Cookie 取值 SameSite=None 和 Secure

第三、修改谷歌浏览器配置
