微信公众平台企业号验证接口、回调PHP版

微信公众平台企业号验证接口、回调 PHP版，本人为了解决这个企业号的验证和发送消息的问题，整整研究了几天时间，因为微信企业号刚推出来，网上资料太少了！后来在一些朋友的帮助下和本人反复调试完善下，终于整理得到了比较理想的文档，经亲测，实验成功。

include_once "WXBizMsgCrypt.php";
// 第三方发送消息给公众平台 
$encodingAesKey = "rpJmhCphnndiCLIcNKcUmhTn2GQBNjISPU9GfsfOlxx"; 
$token = "xxxxxxx"; 
$corpId ="wxa9a0031f24631f9x"; //这里已正确填写自己的corpid 
//公众号服务器数据
$sReqMsgSig = $sVerifyMsgSig = $_GET['msg_signature'];
$sReqTimeStamp = $sVerifyTimeStamp = $_GET['timestamp'];
$sReqNOnce= $sVerifyNOnce= $_GET['nonce'];
$sReqData = file_get_contents("php://input");;
$sVerifyEchoStr = $_GET['echostr']; 
$wxcpt = new WXBizMsgCrypt($token, $encodingAesKey, $corpId); 
if($sVerifyEchoStr){
$sEchoStr = "";
$errCode = $wxcpt->VerifyURL($sVerifyMsgSig, $sVerifyTimeStamp, $sVerifyNonce, $sVerifyEchoStr, $sEchoStr);
if ($errCode == 0) {
print($sEchoStr); 
} else {
print($errCode . "\n\n");
}
exit;
}
 //decrypt
$sMsg = "";  //解析之后的明文
$errCode = $wxcpt->DecryptMsg($sReqMsgSig, $sReqTimeStamp, $sReqNonce, $sReqData, $sMsg);
if ($errCode == 0) { 
$xml = new DOMDocument();
$xml->loadXML($sMsg); 
$reqToUserName = $xml->getElementsByTagName('ToUserName')->item(0)->nodeValue;

if ($errCode == 0) {
//file_put_contents('smg_response.txt', $sEncryptMsg); //debug:查看smg
print($sEncryptMsg);
} else {
print($errCode . "\n\n");
}
} else {
print($errCode . "\n\n");
}
?>
