PayPal IPN侦听器响应

Question

在贝宝的沙箱中进行了充分的测试，并使该过程完美地工作。我已经直播了，但它不起作用。

我通过notify_url从PayPal收到了POST数据。然后，在数据前面使用cmd=_notify-validate将其发送回PayPal。

使用PayPals文档代码，我用这个来发送消息到PayPal。

$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.paypal.com', 443, $errno, $errstr, 30);

$res = stream_get_contents($fp, 1024);

HTTP/1.1 200 OK

Answer 1

您是否使用fwrite/fputs将请求写入套接字？此外，根据响应的长度判断，您可能需要从流中读取超过1024个字节。太接近了。

您可能希望在循环中读取响应：

$resp = '';
while (!feof($fp)) {
    $resp .= stream_get_contents($fp, 1024);
}

然后，可以使用以下方法将标题与正文分开：

list($headers, $response) = explode("\r\n\r\n", 2);
