对paypal付款真的很困惑
更新1：
将$res写入文本文件只会返回单词VERIFIED：
<?php
/*
mysql_connect("localhost", "user", "password") or die(mysql_error());
mysql_select_db("PayPal") or die(mysql_error());
*/
// 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, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);
}
else if (strcmp ($res, "INVALID") == 0) {
$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);
}
}
fclose ($fp);
}
?>
原始问题：
我有以下内容IPN（即时付款通知）脚本，有效，即如果成功则创建成功文件，如果失败则创建失败文件。
paypal 是否会将发布值返回到 IPN 文件，以便我可以确定哪项付款成功或哪项付款失败？
如果是，我如何访问这些值？
如果否，我如何确定哪笔付款已被接受或拒绝？
这是我当前拥有的 IPN 文件中的脚本：
<?php
// 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, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}
else if (strcmp ($res, "INVALID") == 0) {
$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}
}
fclose ($fp);
}
?>
UPDATE 1:
Writing $res to a textfile just returns the word VERIFIED:
<?php
/*
mysql_connect("localhost", "user", "password") or die(mysql_error());
mysql_select_db("PayPal") or die(mysql_error());
*/
// 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, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);
}
else if (strcmp ($res, "INVALID") == 0) {
$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);
}
}
fclose ($fp);
}
?>
ORIGINAL QUESTION:
I have the following IPN (Instant Payment Notification) script, which works, i.e. it creates a successful file if successful and a failed file if failed.
Does paypal return post values to the IPN file so I can figure out which payment was successful or which payment has failed?
If yes, how do I access these values?
If no, how do I figure out which payment has been accepted or declined?
This is the script in the IPN file I currently have:
<?php
// 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, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}
else if (strcmp ($res, "INVALID") == 0) {
$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}
}
fclose ($fp);
}
?>

您的通用脚本中有答案。
Paypal 将在字符串中返回单词“VERIFIED”或“INVALID”。
一个好技巧是将 $res 的值写入日志，您将在最后看到返回的结果。
确保您也使用沙箱进行测试。
另外，http://x.com 上还有一个论坛（他们为该域名支付了多少钱？）
FWIW、Paypal 的IPN 是 PITA。
You have the answer in your generic script.
Paypal will return the word VERIFIED or INVALID in the string.
A good trick is to write the value of $res to your log and you will see the returned result right at the end.
Make sure you use the sandbox for testing as well.
Also there is a forum at http://x.com (how much did they pay for THAT domain?)
FWIW, Paypal's IPN is a PITA.
你好，我
用这种方式实现了 echo
'';会产生这样的东西：
hi i implemented mine this way
doing a echo
'<pre>'.print_r($data,true).'</pre>';would produce something like this :
