Nginx 配置在尝试将 www 重定向到非 www 和 https 时不断抛出重定向循环

  • 772

我正在尝试将所有对我的域的请求重新定向www到非 www url，并将所有请求同时重定向到https。这是我的 nginx 配置：

server {
    listen 80;
    server_name example.com www.example.com;

    location '/.well-known' {
      default_type "text/plain";
      root        /home/letsencrypt;
      allow all;
    }

    return 301 https://example.com$request_uri;
}

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

  include snippets/ssl-example.com.conf;
  include snippets/ssl-params.conf;


  location '/.well-known' {
        default_type "text/plain";
        root        /home/letsencrypt;
        allow all;
  }

  return 301 https://example.com$request_uri;
}

server {
  listen  443 ssl http2;
  server_name  example.com;

  access_log            /var/log/nginx/slmun.access.log;
  error_log             /var/log/nginx/slmun.error.log;

  include snippets/ssl-example.com.conf;
  include snippets/ssl-params.conf;

  location '/.well-known' {
    default_type "text/plain";
    root        /home/letsencrypt;
    allow all;
  }


  location / {
    proxy_pass http://127.0.0.1:8000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forward-Proto http;
    proxy_set_header X-Nginx-Proxy true;

    proxy_redirect off;
  }
}

问题是，我在这里得到了一个重定向循环。浏览器说example.com redirected you too many times.。知道发生了什么吗？

https://slmun.org的卷曲：

<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/1.10.3</center>
</body>
</html>

这是访问日志条目：

162.158.165.25 - - [20/Mar/2017:07:50:53 +0530] "GET / HTTP/1.1" 301 185 "-" "curl/7.47.0"

奇怪的 https 也被重定向。

卷曲slmun.org（这是真正的域）：

<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/1.10.3</center>
</body>
</html>

这是访问日志条目：

162.158.165.25 - - [20/Mar/2017:07:51:49 +0530] "GET / HTTP/1.1" 301 185 "-" "curl/7.47.0"

www 的也有相同的结果。

    您没有在问题中提到您正在使用 CloudFlare。我相信问题出在 CloudFlare，无论是缓存结果还是 PageRule。在进行此诊断时，清除您的 CloudFlare 缓存并禁用任何页面规则。

    下一个选项是您的代理应用程序发送重定向。查看 Nginx 和代理应用的访问日志确认。

    如果您对此不满意，请发布您的 CloudFlare 配置和 Nginx 配置文件的屏幕截图，以及代理配置的日志。

    这是来自 Firefox 的带有 Live HTTP Headers 插件的请求/响应标头。我可以确认一个循环重定向。
