Net :: HTTP.post_form会抛出EOFError吗？

Question

因此,我试图从paypal获取交易详细信息,而无需创建表单,只需通过向网址发送包含必要信息的帖子.这是我的代码片段,我尝试通过表单执行相同的操作.

<form method=post action="https://www.sandbox.paypal.com/cgi-bin/webscr">
      <input type="hidden" name="cmd" value="_notify-synch">
      <input type="hidden" name="tx" value="<%= subscription.tx %>">
      <input type="hidden" name="at" value="<%= @identity_token %>">
      <input type="submit" value="View Details">
    </form>

Ruby对手抛出一个EOFError,我不知道它为什么这样做

paypal_uri = URI.parse('https://www.sandbox.paypal.com/cgi-bin/webscr')
@post_request = Net::HTTP.post_form(paypal_uri , {:tx => @subscription.tx, :at => IDENTITY_TOKEN, :cmd => "_notify-sync"})

Answer 1

URL为https,因此您需要在Net :: HTTP上启用SSL.

require 'openssl'

paypal_uri = URI.parse('https://www.sandbox.paypal.com/cgi-bin/webscr')
req = Net::HTTP::Post.new(paypal_uri.path)
req.set_form_data({:tx => @subscription.tx, :at => IDENTITY_TOKEN, :cmd => "_notify-sync"})
sock = Net::HTTP.new(paypal_uri.host, 443)
sock.use_ssl = true
store = OpenSSL::X509::Store.new
store.add_cert OpenSSL::X509::Certificate.new(File.new('paypal.pem'))
store.add_cert OpenSSL::X509::Certificate.new(File.new('paypal2.pem'))
sock.cert_store = store
sock.start do |http|
  response = http.request(req)
end

要获得CA证书paypal.pem和paypal2.pem,只需手动浏览到PayPal URL,我将为FireFox描述它.单击地址栏左侧的绿色图标,打开对话框,查看证书,详细信息,然后将两个VeriSign证书导出为paypal.pem和paypal2.pem.将它们放在与脚本相同的文件夹中.这应该可以解决你的问题!
