ruby-on-rails – 如何通过代理运行Web请求时设置use_ssl参数？

我正在使用Rails 4.2.7.如何通过代理发送Web请求时设置“use_ssl”参数？我有这个

    res1 = Net::HTTP.SOCKSProxy(TCPSocket::socks_server, TCPSocket::socks_port).start(uri.host, uri.port) do |http|
      http.use_ssl = (uri.scheme == "https")
      resp = http.get(uri, initheader = headers)
      status = resp.code.to_i
      if status == 302 || status == 301
        redirect = resp['location']
      end
      content = resp.body
      content_type = resp['content-type']
      content_encoding = resp['content-encoding']
    end

但当我到达这一行 – “http.use_ssl =(uri.scheme ==”https“)”我得到了例外

IOError: use_ssl value changed, but session already started

最佳答案 根据这个测试样本,第109行：

我会尝试这样的事情：

res1 = Net::HTTP.SOCKSProxy(TCPSocket::socks_server, TCPSocket::socks_port).start(
  uri.host, uri.port, :use_ssl => (uri.scheme == "https")) do |http|

  resp = http.get(uri, initheader = headers)
  status = resp.code.to_i
  if status == 302 || status == 301
    redirect = resp['location']
  end
  content = resp.body
  content_type = resp['content-type']
  content_encoding = resp['content-encoding']
end

如果您没有有效的SSL证书,可以禁用此类SSL验证(不建议用于生产！)
