我正在构建会员区，并且使用avangate.com作为付款系统。如何使用Avangate设置定期订阅
我只想在发生周期性支付时更新数据库中的订户日期和新的到期日期。
我得到这个IPN代码从他们的出发点：
<?php
/* Internet Payment Notification */
$pass = "AABBCCDDEEFF"; /* pass to compute HASH */
$result = ""; /* string for compute HASH for received data */
$return = ""; /* string to compute HASH for return result */
$signature = $_POST["HASH"]; /* HASH received */
$body = "";
/* read info received */
ob_start();
while(list($key, $val) = each($_POST)){
$$key=$val;
/* get values */
if($key != "HASH"){
if(is_array($val)) $result .= ArrayExpand($val);
else{
$size = strlen(StripSlashes($val));
$result .= $size.StripSlashes($val);
}
}
}
$body = ob_get_contents();
ob_end_flush();
$date_return = date("YmdGis");
$return = strlen($_POST["IPN_PID"][0]).$_POST["IPN_PID"][0].strlen($_POST["IPN_PNAME"][0]).$_POST["IPN_PNAME"][0];
$return .= strlen($_POST["IPN_DATE"]).$_POST["IPN_DATE"].strlen($date_return).$date_return;
function ArrayExpand($array){
$retval = "";
for($i = 0; $i < sizeof($array); $i++){
$size = strlen(StripSlashes($array[$i]));
$retval .= $size.StripSlashes($array[$i]);
}
return $retval;
}
function hmac ($key, $data){
$b = 64; // byte length for md5
if (strlen($key) > $b) {
$key = pack("H*",md5($key));
}
$key = str_pad($key, $b, chr(0x00));
$ipad = str_pad('', $b, chr(0x36));
$opad = str_pad('', $b, chr(0x5c));
$k_ipad = $key^$ipad ;
$k_opad = $key^$opad;
return md5($k_opad . pack("H*",md5($k_ipad . $data)));
}
$hash = hmac($pass, $result); /* HASH for data received */
$body .= $result."\r\n\r\nHash: ".$hash."\r\n\r\nSignature: ".$signature."\r\n\r\nReturnSTR: ".$return;
if($hash == $signature){
echo "Verified OK!";
/* ePayment response */
$result_hash = hmac($pass, $return);
echo "<EPAYMENT>".$date_return."|".$result_hash."</EPAYMENT>";
/* Begin automated procedures (START YOUR CODE)*/
}else{
/* warning email */
mail("[email protected]","BAD IPN Signature", $body,"");
}
