nginx - 如何防止谷歌索引我的 https 网址？

Question

当我在谷歌上搜索我的域时，它会显示我网站上的几个 https 网址，因为谷歌喜欢 https，但出于特殊原因我不想索引 https/ssl 版本。

如何避免这种情况，全世界都只通过 htaccess 编写解决方案，但大多数人使用 nginx!如何解决这个问题:

RewriteEngine On
RewriteCond %{HTTPS} =on
RewriteRule ^robots.txt$ robots-deny-all.txt [L]

机器人内容(在额外的机器人中):

User-agent: *
Disallow: /

如何通过 nginx 重写规则做到这一点？

谢谢。

Answer 1

在您的 nginx.conf 文件中，您可以将 header 添加到监听 443(SSL) 的 server block :

server {
    listen 443 ssl;
    ...

    # This header will prevent search engines from indexing your https pages
    add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";
}
