Paypal IPN 无法验证
我正在尝试实施 Paypal IPN，但它从未到达我设置的 url。我编写了一个脚本来记录对此网址的访问，我得到的只是我的访问。
Paypal 需要多长时间发送通知？

IPN 突然开始出现，但现在我无法验证...以下是代码：
$url = 'https://www.paypal.com/cgi-bin/webscr';
$postdata = '';
foreach ($_POST as $i => $v) {
$postdata .= $i . '=' . urlencode($v) . '&';
}
$postdata .= 'cmd=_notify-validate';
$web = parse_url($url);
if ($web['scheme'] == 'https') {
$web['port'] = 443;
$ssl = 'ssl://';
} else {
$web['port'] = 80;
$ssl = '';
}
$fp = @fsockopen($ssl . $web['host'], $web['port'], $errnum, $errstr, 30);
if (!$fp) {
echo $errnum . ': ' . $errstr;
} else {
fputs($fp, "POST " . $web['path'] . " HTTP/1.1\r\n");
fputs($fp, "Host: " . $web['host'] . "\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: " . strlen($postdata) . "\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $postdata . "\r\n\r\n");
while (!feof($fp)) {
$info[] = @fgets($fp, 1024);
}
fclose($fp);
$info = implode(',', $info);
if (eregi('VERIFIED', $info)) {
} else {
}
}
I am trying to implement Paypal IPN but it never reaches the url I've set. I've written a script to log visits to this url and all I get are my visits.
How long does it take for Paypal to sent the notification?
EDIT
IPNs suddenly started to come but now I can't verify...Here is the code:
$url = 'https://www.paypal.com/cgi-bin/webscr';
$postdata = '';
foreach ($_POST as $i => $v) {
$postdata .= $i . '=' . urlencode($v) . '&';
}
$postdata .= 'cmd=_notify-validate';
$web = parse_url($url);
if ($web['scheme'] == 'https') {
$web['port'] = 443;
$ssl = 'ssl://';
} else {
$web['port'] = 80;
$ssl = '';
}
$fp = @fsockopen($ssl . $web['host'], $web['port'], $errnum, $errstr, 30);
if (!$fp) {
echo $errnum . ': ' . $errstr;
} else {
fputs($fp, "POST " . $web['path'] . " HTTP/1.1\r\n");
fputs($fp, "Host: " . $web['host'] . "\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: " . strlen($postdata) . "\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $postdata . "\r\n\r\n");
while (!feof($fp)) {
$info[] = @fgets($fp, 1024);
}
fclose($fp);
$info = implode(',', $info);
if (eregi('VERIFIED', $info)) {
} else {
}
}

我上面已经评论过了。但我很确定 html 编码的
&会弄乱你的回调。URL 编码 和 HTML 编码 之间存在很大差异。
将此
'&'更改为此'&'。&是一个 url/post 字符，用于分隔不同的键/值对集。通过将其更改为&，您可以使整个回调成为单个值。另外，只是一些建议，但我会放弃这个
并用这个已贬值的
eregi替换它。

I already commented above. But I'm pretty sure the html encoded
&is messing up your callback.There's big difference between URL encoding and HTML encoding.
Change this
'&'to this'&'.&is a url/post character used to separate different sets of key/value pairs. By changing it to&, you made your whole callback a single value.Also, just some advice, but I would ditch this
and replace it with this
eregiis depreciated.http://php.net/manual/en/function.eregi.php
