PayPal Express Checkout PHP 没有得到响应

问题描述

我目前正在尝试使用 angelleye codeigniter 库 (https://github.com/angelleye/paypal-codeigniter).我没有收到来自 PayPal 的回复或任何错误.由于没有响应，我得到的唯一错误是未定义的 ACK 索引.没有任何 curl 错误，PayPal 响应返回一个空数组.

I'm currently trying to get PayPal express checkout working using the angelleye codeigniter library (https://github.com/angelleye/paypal-codeigniter). I'm not getting a response or any errors from PayPal. The only error I am getting is an undefined index of ACK due to there not being a response. There are not any curl errors and the PayPal response comes back with an empty array.

有没有办法检查哪里出错了?

Is there a way of checking where this is failing?

运行:

Ubuntu 12.04.5

推荐答案

在/application/libraries/paypal/Paypal_pro.php 中找到 CURLRequest() 函数.应该在第 589 行.

In /application/libraries/paypal/Paypal_pro.php find the CURLRequest() function. Should be at line 589.

在函数中的这一行之后:

After this line in the function:

$Response = curl_exec($curl);

添加以下内容，添加以下内容:

Add the following, add the following:

if($Response === FALSE) {
  echo "cURL Error: " . curl_error($curl);
  exit();
}

然后运行另一个测试.如果发生 curl 错误，您应该能够看到它.

Then run another test. If there is a curl error happening you should be able to see it.
