HTTP到HTTPS Nginx有太多重定向

我有一个在LEMP堆栈上运行的网站.我已经在网站上启用了cloudflare.我正在为https使用cloudflare灵活SSL证书.当我在chrome中打开网站时,它显示网站重定向了你太多次,并且在firefox中检测到服务器正在以永远不会完成的方式重定向该地址的请求.我试图看到其他问题的答案,但似乎都没有解决问题.NGINX conf文件: -

server {
listen 80 default_server;
listen [::]:80 default_server;
server_name mydomain.com www.mydomain.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl http2 default_server;
listen [::]:443 ssl http2 default_server;
root /var/www/html;

index index.php index.html index.htm index.nginx-debian.html;

location / {
    try_files $uri $uri/ =404;
}

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

location ~ /\.ht {
    deny all;
}
}

如果有人能指出我做错了什么,我将非常感激.

由于您使用的是cloudflare灵活SSL,因此您的nginx配置文件将如下所示: -

server {
  listen 80 default_server;
  listen [::]:80 default_server;
  server_name mydomain.com www.mydomain.com;

  if ($http_x_forwarded_proto = "http") {
      return 301 https://$server_name$request_uri;
  }

  root /var/www/html;

  index index.php index.html index.htm index.nginx-debian.html;

  location / {
     try_files $uri $uri/ =404;
  }

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

  location ~ /\.ht {
     deny all;
  }
}
