Nginx 运维之域名验证的方法示例

作者：袖梨 2022-06-30

各公众平台在配置接口域名时会验证开发者对域名的配置权, 生成随机的文本及字符串，让放置在域名根目录可以通过域名直接访问到即通过验证。

示例为验证域名 abc.com 可以通过根路由访问 6CysNYj8Hb.txt 响应体为字符串 01df2ddab4774ba2676a5563ccb79ffa。 

$ curl https://abc.com/6CysNYj8Hb.txt
01df2ddab4774ba2676a5563ccb79ffa

方案一

配置有 root 的 server，直接把随机文档放置在该目录下即可，不需要重启 nginx 服务。

方案二

匹配路由，指定随机文档所在目录, 需要重启 nginx。 

location ~* 6CysNYj8Hb.txt {
 root /data/ftp;
}

方案三（推荐）

匹配路由，直接返回需要验证的随机字符串，需要重启 nginx。 

location = /6CysNYj8Hb.txt {
 default_type text/html;
 return 200 '01df2ddab4774ba2676a5563ccb79ffa';
}

参考

Nginx 的 Location 从零开始配置

nginx 配置返回文本或 json

补充：Nginx域名重定向

1、更改配置文件test.com.conf 

[root@jimmylinux-001 vhost]# vim test.com.conf

server
{
  listen 80;
  server_name test.com test2.com test3.com;
  index index.html index.htm index.php;
  root /data/wwwroot/test.com;
  if ($host != 'test.com' ) {
    rewrite ^/(.*)$ http://test.com/$1 permanent;
  }

}

2、curl测试 

[root@jimmylinux-001 vhost]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@jimmylinux-001 vhost]# /usr/local/nginx/sbin/nginx -s reload
