重定向时nginx www域不起作用

Question

我在使用 http://www.example.com 重定向内容时遇到问题。换句话说，http://example 可以正常工作并重定向到 https，但 http://www.example.com 不能。

下面是我的 nginx 配置

server {
  listen 80;
  listen [::]:80;
  server_name example.com;
  return 301 https://www.example.com$request_uri;
}

server {
 listen 80;
 listen [::]:80;
 server_name www.example.com;
 return 301 https://www.example.com$request_uri;
}

server {

listen 443 ssl http2;
server_name www.example.com;

sendfile on;

ssl_certificate /usr/share/example_chain.crt;
ssl_certificate_key /usr/share/7a45ae3816f4bc8f.pem;
default_type application/octet-stream;

gzip on;
gzip_http_version 1.1;
gzip_disable      "MSIE [1-6]\.";
gzip_min_length   256;
gzip_vary         on;
gzip_proxied      expired no-cache no-store private auth;
gzip_types        text/plain text/css application/json application/javascript application/x- 
javascript text/xml application/xml application/xml+rss text/javascript;
gzip_comp_level   9;

root /usr/share/nginx/html;

location / {
  try_files $uri $uri/ /index.html =404;
 }

}

此外，我有一个 docker 容器，它为我的 ec2 实例上的端口 443 到 docker 容器内的端口 443 提供请求。

在我有这个之前 ->

server {
  listen 80;
  listen [::]:80;
  server_name www.example.com example.com;
  return 301 https://www.example.com$request_uri;
}

您可以使用 nginx 中的 IF 模块来解决此问题。参考下面的配置。

server {
         listen 80;
         server_name example.com www.example.com;
         return 301 https://www.example.com$request_uri;
}

server {
        listen 443;
        server_name example.com;
        root /var/www/html;
        index index.html index.php;

        location / {
           try_files $uri $uri/ /index.php?$args;
        }


        ssl on;
        ssl_certificate /etc/nginx/ssl/cert.crt;
        ssl_certificate_key /etc/nginx/ssl/key.key;
        ssl_session_timeout 5m;

        if ($scheme = http) {
                 rewrite ^/(.*)$ https://www.example.com/$1 permanent;
         }

         if ($host !~* ^www\.) {
                 rewrite ^/(.*)$ https://www.example.com/$1 permanent;
         }


}
