我已经使用沙箱获取了 Paypal IPN 在交易后返回的信息。我遇到的问题是 IPN 没有发送买家地址信息，但我仍然可以得到他的名字和买家的姓氏。我也可以毫无问题地获取交易 ID 或购买的商品信息。我无法获得的唯一变量是所有买家地址信息，如 $_POST['address_name'] 或 $_POST['address_city']。这是我的 HTML 表单：
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

这是我的贝宝通知文件的开始：
// lire le formulaire provenant du système PayPal et ajouter 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// renvoyer au système PayPal pour validation
$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]);
}
$_req = 'cmd=_notify-validate';
foreach ($myPost as $key => $value) {
$value = urlencode(stripslashes($value));
$_req .= "&$key=$value";
}
// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://ipnpb.paypal.com', 443, $errno, $errstr, 30);
// récupération des informations de paypal
$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'];
$custom = explode("||", $_POST['custom']);
$id_user = $custom[0];
$dureeContrat = $custom[1];
$first_name = $_POST["first_name"];
$last_name = $_POST["last_name"];
$address_city = $_POST["address_city"];
$address_country = $_POST["address_country"];
$address_country_code = $_POST["address_country_code"];
$address_name = $_POST["address_name"];
$address_state = $_POST["address_state"];
$address_street = $_POST["address_street"];
$address_zip = $_POST["address_zip"];
这是 IPN 返回的 $POST 变量：
Key: mc_gross
Key: protection_eligibility
Key: payer_id
Key: tax
Key: payment_date
Key: payment_status
Key: charset
Key: first_name
Key: option_selection1

Key: btn_id
Key: last_name
Key: receiver_email
Key: payment_fee
Key: shipping_discount
Key: insurance_amount
Key: receiver_id
