我要深入了解我的paypal ipn代码。我使用INSERTS来确保我知道代码停止工作的位置。代码不会通过此部分。这是代码:
$res = fgets ($fp, 1024);
因此,它永远不会到达
if (strcmp($res, "VERIFIED") == 0) {
以下是大部分代码:
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
$req .= "&$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, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp($res, "VERIFIED") == 0) {
有人知道为什么它没有通过paypal ipn代码的这一部分吗?
