Ruby net/http 无法连接到 TLS 代理答案

【问题描述】：

Rubys net/http 允许您指定一个代理来路由所有请求，如下所示：

Net::HTTP.new("host", "443", "proxyHost", 8080, "proxyUsername", "password")

这在与 HTTP 代理一起使用时可以正常工作，但是当使用 TLS 代理而不是 HTTP 时会失败：

def tls_proxy(data)

  uri = URI("https://example.com/post")
  client = Net::HTTP.new("host", "443", "proxyHost", 8443, "proxyUsername", "password")

  client.ssl_version = :TLSv1_2
  client.use_ssl = true

  request = Net::HTTP::Post.new(uri.path)

  request['Content-type'] = 'application/json'
  request.body = data

  client.request(request)

end

有没有办法让它与 TLS 代理一起工作，或者也许有一个支持 TLS 代理的库的替代方案？

【解决方案1】：

你可以试试httparty gem。

require 'httparty'

options = {
  http_proxyaddr: '127.0.0.1',
  http_proxyport: '8443',
  http_proxyuser: 'johndoe',
  http_proxypass: '123456'
}

response = HTTParty.get('https://example.com', options)

【讨论】：

它似乎也不支持 TLS 代理，如果我尝试使用HTTP 代理请求通过就好了，而 TLS 端口返回与“net/http”相同的错误将返回“未捕获的异常：到达文件结尾”。
