Rails 始终听众 Paypal IPN return 无效

Question

我已经为我的 IPN 构建了一个侦听器。我可以通过 IPN 模拟器接收请求并且所有参数都是正确的，但是当我将它发送回 link for sending my request to make validations 时它总是 return 无效。

我曾尝试将我的 PayPal 帐户的编码更改为 UTF-8，但没有成功。

我没有为此使用任何 gem，我也不期待这个。

 class PaymentNotificationController  [:create] #Otherwise the request from PayPal wouldn't make it to the controller


  def create
    response = validate_IPN_notification(request.raw_post)
    case response
    when "VERIFIED"
      P 'worked'

    when "INVALID"
        p 'did not work'
    else
    end
    render :nothing => true, :status => 200, :content_type => 'text/html'
  end


  protected 

  

  def validate_IPN_notification(raw)

    uri = URI.parse('https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_notify-validate')
    #uri = URI.parse('https://www.paypal.com/cgi-bin/webscr?cmd=_notify-validate')
    http = Net::HTTP.new(uri.host, uri.port)
    http.open_timeout = 60
    http.read_timeout = 60
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    http.use_ssl = true
    response = http.post(uri.request_uri, raw,
                         'Content-Length' => "#{raw.size}",
                         'User-Agent' => "My custom user agent"
                       ).body
  end
end

请帮帮我，我已经卡了一下午了，想不通。

Answer 1

我觉得你的问题是not follow exactly what papal requires

来自Paypal document

Your listener HTTP POSTs the complete, unaltered message back to PayPal.

Note This message must contain the same fields, in the same order, as the original IPN from PayPal, all preceded by cmd=_notify-validate. Further, this message must use the same encoding as the original.

所以你 validate function 会是：

def validate_IPN_notification(ipn_url)
  validate_url = "#{ipn_url}?cmd=_notify-validate"
  # Post validate_url
  ...
end

注意 ipn_url 与 IPN

相同 url

原来是一个 Windows 问题，我不知道如何解决。

我在我的 Ubuntu 15 上尝试了同样的方法，效果很好。
