![传入主机标头加倍](https://linux22.com/image/1587455/%E4%BC%A0%E5%85%A5%E4%B8%BB%E6%9C%BA%E6%A0%87%E5%A4%B4%E5%8A%A0%E5%80%8D.png)
我在 Ubuntu 18.04 服务器上使用 Nginx 网络服务器,该服务器装有 Gunicorn 和 Django。我的服务器目前处于宕机状态,因为传入的主机标头总是重复。
当我向服务器发出请求时,Django 给出错误信息
Invalid HTTP_HOST header: 'dt-testing.com,dt-testing.com'. The domain name provided is not valid according to RFC 1034/1035.
我无法弄清楚传入标头在哪里被复制了。我尽我所能地梳理了我的 nginx.conf 和 sites-available 文件,但根本没有发现任何可疑的东西。

# #return 301 https://$host$request_uri*;
# return 301 https://$host$request_uri; # could this be causing the doubling of the URL?

我遗漏了什么吗?我不明白标题在哪里重复并连接在一起。
答案1
我认为你的 nginx.conf 设置了两次标头:
proxy_set_header Host $host;
include proxy_params;
因此,标题在 sites-available/ 中设置一次,我敢打赌,您会在下proxy_params
一行包含的文件中找到第二份副本。
答案2
我弄清楚了问题所在。我怀疑 cerbot renew 以某种方式更新了 nginx 软件,这导致它以不同的方式呈现上面的配置文件。proxy set header 这一行是将传入 header 加倍的那一行,但由于我在 Django 端的 Python 代码中有一个错误,因此它不起作用。
