<?php

foreach ($_GET as $key=>$value) 
{
 logger("Key: $key; Value: $value");
}
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
logger($postStr);

if (isset($_GET)){
 echo "success";
}

//日志記錄
function logger($log_content)
{
 $max_size = 100000;
 $log_filename = "log.xml";
 if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);}
 file_put_contents($log_filename, date('H:i:s')." ".$log_content."\r\n", FILE_APPEND);
}
?>

上述程序的作用是：

獲取post到url的通知，他們以GET變量形式

獲取post的XML數(shù)據(jù)包

返回成功消息 success

將notice.php的完整路徑放入JS API支付的notice url中。

$wxPayHelper->setParameter("notify_url", http://www.doucube.com/wxpay/notice.php);

這樣當(dāng)交易完成后，該url將收到通知，并記錄在日志文件中，我們的測(cè)試如下所示：

獲得的GET變量及XML如下所示：
