PayPal IPN 在沙箱中返回无效 [英] PayPal IPN returns invalid in sandbox

问题描述

我正在使用 PayPal IPN 创建支付网关.提交付款后，我检索了 PayPal 的回复.这是我收到的(PHP var_dump):

I'm creating a payment gateway using PayPal IPN. After submitting the payment, I retrieve PayPal's response. Here is what I receive (PHP var_dump):

    array(45) {
    ["mc_gross"]                    => string(4)  "1.00"
    ["protection_eligibility"]      => string(10) "Ineligible"

    ["payment_type"]                => string(7)  "instant"
    ["last_name"]                   => string(5)  "buyer"

    ["receiver_email"]              => string(38) "[myemail]"
    ["quantity1"]                   => string(1)  "1"
    ["pending_reason"]              => string(10) "unilateral"
    ["txn_type"]                    => string(4)  "cart"
    ["mc_gross_1"]                  => string(4)  "1.00"

}

然后我执行以下操作:

$responseURL = "https://sandbox.paypal.com/cgi-bin/webscr?";
$params = "cmd=_notify-validate&" .http_build_query($_REQUEST);

var_dump(file_get_contents($responseURL.$params));

返回:INVALID

有什么建议吗?在沙盒中测试可能不起作用吗?

Any advice? Is testing perhaps not working in Sandbox?

推荐答案

需要发布数据；这是我使用的工作代码:

You need to post the data; here is working code that I use:

$req = 'cmd=_notify-validate';

foreach($_POST as $key => $value) {
    $value = urlencode($value);
    $req .= "&{$key}={$value}";
}

$res = '';
$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));   
$res = curl_exec($ch);
curl_close($ch);

if(strcmp($res, "VERIFIED") == 0) 
{
    //VALID
}
