Paypal IPN Sandbox - IPN侦听器 - 未经验证或无效

Question

我在开发人员中设置了测试帐户Business and Personal以尝试沙盒模式.

我在我的网站上创建了一个付款按钮.我点击按钮,然后转到贝宝.测试用户个人帐户用于支付.当我查看Paypal商业帐户时,付款通过并完成.重定向到我的网站运作良好.

所以在我看来,我应该有一个"工作"系统.

我的IPN侦听器虽然没有返回已验证或无效.

这是我的倾听者:

 <?php
 require("../widgets/init.inc.php");

//Test the script is launced
$log_query = mysql_query("INSERT INTO `log` VALUES (' ','zz','ff','rr', 'rr')");                

// Link to PayPal Codes //
// https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_html_IPNandPDTVariables // 

// 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";

//For the below line i have tried "www.sandbox.paypal" as well as "www.paypal"
$fp = fsockopen ('ssl://www.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'];
$txnId = $_POST['txn_id'];
$receiverEmail = $_POST['receiver_email'];
$payerEmail = $_POST['payer_email'];
//$id = ($_POST['custom']);

if (!$fp) {

} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {

if ($payment_status=='Completed') {

//$txnIdCheck = mysql_query("SELECT `txnId` FROM `log` WHERE `txnId`='".$txnId."'");  
//if (mysql_num_rows($txnIdCheck) !=1) {

// enter your email address associated with your paypal account here // 
if ($receiverEmail=='biztester1@mydomain.dk') { 

/* when a new premium member makes payment paypal will update our database.

//Check if verified is launced          
$log_query_2 = mysql_query("INSERT INTO `log` VALUES (' ','yes','yes','yes', 'yes')");          

//$log_query = mysql_query("INSERT INTO `log` VALUES (' ','".intval($id)."','".$txnId."','".$payerEmail."', now())");                   

//$update_premium = mysql_query("UPDATE `memberAdmin` SET `premium`=1, `premiumDate`=now() WHERE `id`=".intval($id)."");    

}       
//}
}
}
else if (strcmp ($res, "INVALID") == 0) {         
//Check if invalid is launced
$log_query_2 = mysql_query("INSERT INTO `log` VALUES (' ','no','no','no', 'no'");   
}
}
fclose ($fp);
}
?>

我在paypal商业帐户网站上激活了IPN.我从paypal发了一个返回信息的txt文件,它看起来像这样:

看起来要比我认为应该做的更难.

我发现了问题..而且令人生气的事情就是PayPal文件错了.我不明白文档可以说按此按钮并按下此按钮..当网站中没有这样的按钮时.. .

对于此问题 - 文档确实说明了错误的方法/不包含所需的完整代码.

问题:$ res返回了这个:

HTTP/1.0 400 Bad Request
Server: BigIP
Connection: close
Content-Length: 19
Invalid Host header

需要添加的是:

$header .= "Host: www.sandbox.paypal.com\r\n";

然后上面的代码如下所示:

// post back to PayPal system to validate //
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Host: www.sandbox.paypal.com\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);

这是我最终使用的完整代码:

<?php
require("../widgets/init.inc.php");         

// Link to PayPal Codes //
// https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_html_IPNandPDTVariables // 

// 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 .= "Host: www.sandbox.paypal.com\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'];
$txnId = $_POST['txn_id'];
$receiverEmail = $_POST['receiver_email'];
$payerEmail = $_POST['payer_email'];
//$id = ($_POST['custom']);


if (!$fp) {

} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);

$log_query_pre = mysql_query("INSERT INTO `log` VALUES (' ','$receiverEmail','$payment_status','$res', 'yes')");    

  if (strcmp ($res, "VERIFIED") == 0) {

if ($payment_status=='Completed') {

//$txnIdCheck = mysql_query("SELECT `txnId` FROM `log` WHERE `txnId`='".$txnId."'");  
//if (mysql_num_rows($txnIdCheck) !=1) {

// enter your email address associated with your paypal account here // 
if ($receiverEmail=='biztester1@mydomain.dk') { 

/* when a new premium member makes payment paypal will update our database.

$log_query_2 = mysql_query("INSERT INTO `log` VALUES (' ','yes','yes','yes', 'yes')");

//$update_premium = mysql_query("UPDATE `memberAdmin` SET `premium`=1, `premiumDate`=now() WHERE `id`=".intval($id)."");    

}       
//}

fclose ($fp);
