无法将 https://www.example.com 重定向到 https://example.com

Question

我在 Ubuntu 上使用 Nginx，能够将 www.example.com 重定向到 https://example.com，但不能从 SSL 重定向到带有 www 子域的 SSL。

这是我的/etc/nginx/sites-enabled/myapp.conf：

# redirect non https traffic for the correct domains
server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 default_server;
    listen [::]:80 default_server;

    server_name www.example.com;
    return 301 https://example.com$request_uri;
    return 404; # managed by Certbot

}

server {
    listen [::]:443 ssl ipv6only=on;
    listen 443 ssl;
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    # server for these domains
    server_name example.com;

    # first try to serve the erb version.
    index index.html;

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/myapp/code/public;

    # Turn on Passenger
    passenger_enabled on;
    passenger_ruby /usr/local/rvm/gems/ruby-2.5.1/wrappers/ruby;
}

有没有办法将所有 www 子域的流量重定向到根域，即使在 https:// 之后输入 www URL？

谢谢，感谢您的帮助。

Answer 1

是的，添加以下服务器块：

# remove 'www'
server {
    listen 80;
    listen 443 ssl;
    server_name www.domain.com;
    return 301 https://example.com$request_uri;
}

这是来自nginx docs。
