redirect - Nginx - 从 http ://to https://without www 正确重定向

Question

按照我的配置文件:

server {
   listen [::]:443 ipv6only=off ssl;
   server_name www.example.com;
   // ssl stuff
   return 301 https://example.com$request_uri;
}

server {
   listen  [::]:80 ipv6only=off;
   return 301 https://example.com$request_uri;
}

server {
   listen [::]:443 ssl;  
   server_name example.com;
   // php and ssl stuff
}

我不明白为什么 http://www.example.com 重定向到 https://www.example.com 然后到 https//example.com。如何从 http://www.example.com 直接重定向到 https://example.com？

Answer 1

在没有 WWW 的情况下从 HTTP 重定向到 HTTPS 的 NGINX 配置:

server {
   listen 80 default_server;
   listen  [::]:80 default_server;
   server_name example.com www.example.com;
   return 301 https://example.com$request_uri;
}
server {
   listen 443 default_server;
   listen [::]:443 ssl http2 default_server;
   server_name example.com www.example.com;
   ##here-ssl-settings##
   return 301 https://example.com$request_uri;
}
