【问题描述】：
我有以下 HTML 表单
<form action="https://sandbox.paypal.com/cgi-bin/webscr" method="post" id="paypalpost" name="paypalpost">
<input type="hidden" name="rm" value="2"/>
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="vbnetdiscuss@yahoo.com">
<input type="hidden" name="item_name" value="Wedding Gift">
<input type="hidden" name="currency_code" value="EUR">
<input type="hidden" name="amount" value="<?php echo $value['total'];?>">
<input type="hidden" name="return" value="http://developwithus.com/wedding/return.php">
<input type="hidden" name="cancel_return" value="http://developwithus.com/wedding/return.php?status=0">
<input onclick="return submitatoc();" disabled type="submit" name="submit" id="pay" class="buttonBlueBg" value="Checkout" style="cursor:pointer;">
</form>
我提到返回 URL 为 http://developwithus.com/wedding/return.php 在其上，（我已经从 https://cms.paypal.com/cms_content/US/en_US/files/developer/IPN_PHP_41.txt 下载了这个并添加
<?php
print_r('<pre>');
print_r($_POST);
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST 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://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
// assign posted variables to local variables
$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 = $_POST['payer_email'];
if (!$fp) {
// HTTP ERROR
echo "HTTP Error";
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
echo $res;
if (strcmp ($res, "VERIFIED") == 0) {
// check 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 payment
echo("verified");
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
echo ("invalid");
}
}
fclose ($fp);
}
echo "end";
?>
但是我收到了 Bad Request 作为响应，如果我去 paypal 沙盒帐户并付款并返回。
