# Nginx配置http跳转https访问

# nginx的rewrite方法

可以把所有的HTTP请求通过rewrite重写到HTTPS上

配置

# 方法一

server{
   listen 80;
   server_name XXXXX.com;
   rewrite ^(.*)$  https://XXXXXX.com permanent;
   location ~ / {
     index index.html index.php index.htm;
   }
}

# 方法二

server{
   listen 80;
   server_name XXXXX.com;
   return 301 https://$server_name$request_uri;
   location ~ / {
     index index.html index.php index.htm;
   }
}

# 方法三

server{
   listen 80;
   server_name XXXXX.com;
   rewrite ^(.*)$  https://$host$1 permanent;
   location ~ / {
     index index.html index.php index.htm;
   }
}

# nginx的497状态码

497 – normal request was sent to HTTPS

当前站点只允许HTTPS访问，当使用HTTP访问nginx会报出497错误码

可以使用error_page 把497状态码链接重新定向到HTTPS域名上

server{
   listen 80;
   server_name XXXXX.com;
   error_page 497  https://$host$uri?$args;
   location ~ / {
     index index.html index.php index.htm;
   }
}

# meta刷新作用将http跳转到HTTPS

# index.html

<html>
 <meta http-equiv="refresh" content="0;url=https://XXXX.com/">
</html>

# nginx配置

server{
   listen 80;
   server_name XXXXX.com;
   location ~ / {
   root /var/www/test/;
     index index.html index.php index.htm;
   }
   error_page 404 https://xxxx.com
}
