我的 NGINX 服务器块是否设置不正确（HTTPS 301 和资产未在浏览器中缓存）？

我的 NGINX 服务器块是否设置不正确（HTTPS 301 和资产未在浏览器中缓存）？

我继承了一台服务器，并诊断出几个问题，且某些页面速度性能测试正在下降。

1) 在服务器块中，某些请求被重定向到https://25parkrow.com。例如，如果您只输入wwww.25parkrow.com或，25parkrow.com就会发生重定向。但如果您输入，https://25parkrow.com则不会发生重定向。如您所见，重定向发生在包含的服务器块中。这是可以接受的做法吗？如果不是，我该如何避免这些重定向？

2) 我在设置静态资产的过期标头时遇到问题。如果我更新服务器上的文件并重新加载 nginx 服务器，浏览器将看不到更新的资产。

我读了这篇文章：为 nginx 提供的静态内容设置过期标头。然而这让我很困惑，因为我不知道应该把缓存头放在下面的服务器块的什么位置。

nginx.conf：

events {
    worker_connections 768;
    # multi_accept on;
}

http {

/etc/nginx/sites-enabled/active（仅一个文件处于活动状态）：

server {

  root /var/www/html;

  # Add index.php to the list if you are using PHP
  index index.html index.htm index.nginx-debian.html;

  server_name 25parkrow.com www.25parkrow.com;

  # Any route that doesn't have a file extension (e.g. /devices)
  location / {
    try_files $uri $uri/ /index.html;
  }

  if ($host = www.25parkrow.com) {
    rewrite ^(.*) https://25parkrow.com$request_uri;

  listen 443 ssl; # managed by Certbot

  ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
  listen 80 default_server;
  server_name 25parkrow.com www.25parkrow.com;

  if ($host = www.25parkrow.com) {
      return 301 https://$host$request_uri;
  } # managed by Certbot


  if ($host = 25parkrow.com) {
      return 301 https://$host$request_uri;
  } # managed by Certbot

  return 404; # managed by Certbot
}

  1. 预计在安装 LetsEncrypt 证书时，您选择将 http 重定向到 https。您可以在 nginx 配置文件中注释重定向以禁用此功能。

  2. 在您现有的 nginx 配置中，http 被重定向到 https。因此，请确保在 https 服务器块中配置“expire headers”。
