带 ssl 的 http 服务器不适用于 nc

如果运行：

cat index.html  | nc --ssl --broker --keep-open   -l 443

在客户端浏览器继续尝试连接但没有成功。我的意思是，html 页面无法加载。

此外，curl 输出为：

curl -v  -k https://10.0.3.226/index.html

有办法让它发挥作用吗？

PS：nc 是 nmap 包中的 ncat。

HTTP/1 响应需要 HTTP 标头（状态代码、元数据）和 HTTP 正文（即内容）。您的index.html可能只是内容。如果这是一个可接受的响应，取决于您的客户端是否支持 20 多年已过时的 HTTP/0.9 协议（不发送标头）。很多人没有。
