Apache https://domain.com重定向到https://www

我的nginx配置主要使用https，所有从http到https的重定向都正常工作，除了从哪个需要重定向到哪个可以有人告诉我哪里出了问题

我曾尝试在服务器块中添加重定向，以侦听443 for example.com重定向到www.example.com，但我遇到了相同的问题

server {
    server_name www.example.com;
    index index.php index.html index.htm;
    root /var/www/qc/public;

    error_log  /var/www/qc/error.log debug;
    access_log /var/www/qc/access.log;

    location / {
        include /etc/nginx/mime.types;
        index index.php;
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    listen 443 ssl; # managed by Certbot

    location /phpmyadmin {
        root /usr/share/;
        index index.php index.html index.htm;
        location ~ ^/phpmyadmin/(.+\.php)$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        }
        location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt$
            root /usr/share/;
        }
    }

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # m$
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; #$
}
server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    server_name example.com;
    return 404; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # m$
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; #$
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    server_name www.example.com example.com;
    return 301 https://www.example.com$request_uri;
    listen 80;
    return 404; # managed by Certbot
}

我希望url重定向到example.com括号中的

，您不需要“if（$host=example.com）{” 由于您已经通过设置“server_name example.com；”对进入此括号的主机进行了分隔。此外，当您重定向到https://$host$request_uri；，您将重定向到example.com，而不是www.example.com，从而创建了一个无限的重定向循环

这有帮助，这是example.com配置，应该可以工作：

server {

 location / {

    return 301 https://www.example.com$request_uri;
  }

    server_name example.com;
    return 404; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # m$
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; #$
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

这将创建一个循环：

if（$host=example.com）{return301 https://$host$request_uri；}

谢谢，我用

return301替换了if块https://www.example.com$request_uri；server_name example.com；return 404；#由Certbot管理
