【问题描述】：
所以我已经在这里坐了大约六个小时，试图弄清楚为什么我的 PHP 示例代码不起作用。一切正常，直到我必须使用 PayPal 通过 cURL 进行验证。下面你可以看到我的代码和我的错误。我一直在尝试有关读/写权限、PHP 5.3.7 或更高版本、php.ini 修改与修改我的 php 脚本的各种方法。我完全没有想法，任何帮助将不胜感激。
PHP：
<?php
// STEP 1: read POST data
// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream.
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode ('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
$value = urlencode(stripslashes($value));
} else {
$value = urlencode($value);
}
$req .= "&$key=$value";
}
$myfile = fopen("testfile.txt", "w");
fwrite($myfile,$req);
// Step 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://sandbox.paypal.com/cgi-bin/webscr');
curl_setopt($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($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
// In wamp-like environments that do not come bundled with root authority certificates,
// please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set
// the directory path of the certificate as shown below:
curl_setopt($ch, CURLOPT_CAPATH,'C:\Users\Administrator\Desktop\ca-bundle.crt');
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
if( !($res = curl_exec($ch)) ) {
fwrite($myfile, "Got " . curl_error($ch) . " when processing IPN data");
curl_close($ch);
exit;
}
curl_close($ch);
frwite($myfile,$res);
// inspect IPN validation result and act accordingly
if (strcmp ($res, "VERIFIED") == 0) {
// The IPN is verified, process it
} else if (strcmp ($res, "INVALID") == 0) {
// IPN invalid, log for manual investigation
}
// inspect IPN validation result and act accordingly
if (strcmp ($res, "VERIFIED") == 0) {
// The IPN is verified, process it:
// check whether the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process the notification
// assign posted variables to local variables
fwrite($myfile,"verified");
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
// IPN message values depend upon the type of notification sent.
// To loop through the &_POST array and print the NV pairs to the screen:
foreach($_POST as $key => $value) {
echo $key." = ". $value."<br>";
}
} else if (strcmp ($res, "INVALID") == 0) {
// IPN invalid, log for manual investigation
echo "The response from IPN was: <b>" .$res ."</b>";
}
?>
错误：
Got error setting certificate verify location: CAFile:'C:\Users\Administrator\Desktop\ca-bundle.crt' CAPath:none when processing IPN data
【问题讨论】：
-
不是 php 也不是 wamp 人，但这听起来像是您的网络应用程序没有 permissions/access to stated directory 的问题
-
是的，我之前已经检查过该链接，但我的权限设置为管理员、管理员、IUSER、IIS_USERS 的完全控制
-
看看sanity check 对找出实际用户是否有帮助（对于我们 ASP.net 人来说，我们通常是应用程序池用户）。
