<p>httpie 拒绝信任自签名证书</p>

我不完全理解问题 #480 的讨论，但我认为这个问题的根本原因可能是相同的。 我需要 httpie 来信任自签名证书。 从技术上讲，它是一个自签名中间证书颁发机构，但我可以使用来自该机构的实际服务器证书之一并获得相同的结果。 该证书满足我的 Mac (OS 10.12) 上的所有其他应用程序，包括 curl。 Httpie 根本不会相信它。 示例输出：

如果我使用--verify=no ，则接受连接。 我已经尝试将证书文件转换为 DER 格式而不是 PEM 而不做任何更改。

Httpie 是通过 Homebrew 安装的，它安装了自己的 Python3 作为依赖项。
