无法使用 HTTParty 获取对等证书

Question

我在 MacBook (macOS 10.14.3) 上安装了 OpenSSL 1.1.1b（通过 Homebrew 安装）、ruby 2.6.0（通过 rvm 安装）和 HTTParty 0.16.4（通过 [安装） =22=]).根据this example，应该可以下载网站的对等证书。但是，当我在我的机器上尝试这样做时，它失败了：

require "httparty"

peer_cert = nil

HTTParty.get("https://www.example.com") do |fragment|
  peer_cert ||= fragment.connection.peer_cert
end

p peer_cert

有错误

我查看了存储库中未解决的问题，并进行了一些谷歌搜索，但没有任何结果。我目前不知所措。任何帮助将不胜感激，谢谢！

更新：虽然我想知道为什么 HTTParty 不起作用，但可以。

Answer 1

0.16.4 没有 connection Source

您所指的 "example" 对应于其他更改

因此看来您需要直接从 github 安装才能使用此功能，或者等到下一个版本发布。
