Nginx将所有流量重定向到HTTPS和非www

Question

有我认为是一个简单的问题，但无法弄清楚。我的目标是让HTTPS非www。

非HTTPS流量正在被正确重定向，但我无法弄清楚的最后一个是将HTTPS www流量重定向到HTTPS非www。

Working:
http://example.com -> https://example.com  
http://www.example.com -> https://example.com 
https://example.com (no redirect needed)
Not Working:
https://www.example.com -> https://example.com (not working)

server {
root /var/www/example.com/;
index index.php index.html index.htm;
server_name example.com www.example.com;
location / {
try_files $uri $uri/ =404;
}
location ~ .php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.3-fpm.sock;
}

listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot

}
server {
if ($host = www.example.com) {
return 301 https://example.com$request_uri;
} # managed by Certbot

if ($host = example.com) {
return 301 https://example.com$request_uri;
} # managed by Certbot
listen 80;
listen [::]:80;
server_name example.com www.example.com;
return 404; # managed by Certbot
}

Answer 1

所以我在 SSL 服务器块中缺少 if 语句

添加：

if ($host = www.example.com) {
return 301 https://example.com$request_uri;
} # managed by Certbot
