Nginx 强制跳转到HTTPS

在Nginx站点配置中增加一行

rewrite ^(.*)$ https://$host$1 permanent;

Nginx配置有2中情况, 80 443在同一个server{} 和不同server{}

第一种  ( 80端口 和 443端口是分开的两个server{} ):

server {
    listen   80;
    listen   [::]:80;

    server_name www.example.com;

    return 301 https://$server_name$request_uri;
}
server {
    listen   443 ssl;

    server_name www.example.com;

    ssl_certificate        /path/www.example.com.crt;
    ssl_certificate_key  /path/www.example.com.key;

}

第二种 (80 443端口在同一个server{} ):

server {
    listen   80;
    listen   [::]:80;
    listen   443 ssl;

    server_name www.example.com;

    ssl_certificate        /path/www.example.com.crt;
    ssl_certificate_key  /path/www.example.com.key;

    if ($scheme = http) {
        return 301 https://$server_name$request_uri;
    }
}
