Nginx 如何通过单次重定向将 HTTP 非 www 重定向到 HTTPS www？

我将端口 80 上的传入 HTTP 流量重定向到端口 443 上的 HTTPS。在那里，我将非 www 重定向到 www：

http://example.com->https://example.com-->https://www.example.com

google pagespeed insights 似乎将此算作“多次重定向”。它似乎也确实在每次重定向之间引入了 300-400 毫秒的延迟。

有没有办法可以在所有情况下一次性完成重定向？

  1. HTTP 非 www -> HTTPS www
  2. HTTP www -> HTTPS www
  3. HTTPS 非 www -> HTTPS www
  4. HTTPS www -> HTTPS www

我的配置文件如下：

server {
        listen 80;
        server_name example.com;
        rewrite ^/(.*) https://example.com/$1 permanent;
}

server {
        root /var/www/html;

        index index.php index.js index.html index.htm index.nginx-debian.html;

        server_name example.com;
        return 301 https://www.example.com$request_uri;
        ssl_certificate /ssl/example.com.chained.crt;
        ssl_certificate_key /ssl/example.com.key;

        location / {
        proxy_pass http://localhost:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        }

        location /wordpress {
        proxy_pass http://localhost:8090;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        }
}

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

        root /var/www/html;

        index index.php index.js index.html index.htm index.nginx-debian.html;

        server_name www.example.com;
        ssl_certificate /ssl/example.com.chained.crt;
        ssl_certificate_key /ssl/example.com.key;

        location / {
        proxy_pass http://localhost:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        }

        location /wordpress {
        proxy_pass http://localhost:8090;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        }
}

在此配置部分，您可以：

  • 你可以捕获多个名字示例.com和www.example.com
  • 您可以直接重定向至www.example.com

所有重定向配置的示例：

server {
        listen 80;
        server_name example.com  www.example.com;
        rewrite ^/(.*) https://www.example.com/$1 permanent;
}

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

    server_name example.com;
    ssl_certificate /ssl/example.com.chained.crt;
    ssl_certificate_key /ssl/example.com.key;
    rewrite ^/(.*) https://www.example.com/$1 permanent;
}


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

    server_name www.example.com ;

    # HERE you push all you configuration for HTTPS://WWW.EXAMPLE.COM

    #.../.../

}
