如何使用 Nginx 将 domain.com 重定向到 www.domain.com？

我想在我的 Nginx 服务器上将 domain.com 重定向到 www.domain.com。但是我的配置不起作用，并在互联网浏览器中显示错误消息：

页面未正确重定向

我添加了此行来执行重定向：

return 301 $scheme://www.s1biose.com$request_uri;

如何纠正这个错误？这是我的配置：

server {
    #listen 80;
    #listen [::]:80 ipv6only=on;
    server_name s1biose.com www.s1biose.com;
    return 301 $scheme://www.s1biose.com$request_uri;
    root /var/www/www-s1biose-com/web;

无论是否使用 www 访问网站，您的“return 301”行都会运行，导致浏览器无限重定向。要仅为 site.com 返回 301，请从主服务器块中删除“return 301”，只让它监听www.site.com，并为 site.com 创建单独的服务器块。

server {
    #listen 80;
    #listen [::]:80 ipv6only=on;
    server_name www.s1biose.com;
    root /var/www/www-s1biose-com/web;
