支付宝服务商第三方应用如何配置应用网关

[SifuLi]

网关代码中的验证无法使用：$result = Pay::alipay()->callback();

返回要求是XML，并要签名。支付宝的demo
`
class Gateway {

public function verifygw($is_sign_success) {
	$biz_content = HttpRequest::getRequest ( "biz_content" );
	$disableLibxmlEntityLoader = libxml_disable_entity_loader(true);
	$xml = simplexml_load_string ( $biz_content );
	libxml_disable_entity_loader($disableLibxmlEntityLoader);
	// print_r($xml);
	$EventType = ( string ) $xml->EventType;
	// echo $EventType;
	if ($EventType == "verifygw") {
		require 'config.php';
		require_once 'AopSdk.php';
		require_once 'function.inc.php';
		$as = new AopClient();
		$as->rsaPrivateKey=$config['merchant_private_key'];
		// global $config;
		// print_r ( $config );
		if ($is_sign_success) {
			$response_xml = "<success>true</success><biz_content>" . $config ['merchant_public_key'] . "</biz_content>";

		} else { // echo $response_xml;
			$response_xml = "<success>false</success><error_code>VERIFY_FAILED</error_code><biz_content>" . $config ['merchant_public_key_file'] . "</biz_content>";
		}
		
		$mysign=$as->alonersaSign($response_xml,$config['merchant_private_key'],$config['sign_type']);
		$return_xml = "<?xml version=\"1.0\" encoding=\"".$config['charset']."\"?><alipay><response>".$response_xml."</response><sign>".$mysign."</sign><sign_type>".$config['sign_type']."</sign_type></alipay>";

		writeLog ( "response_xml: " . $return_xml );
		echo $return_xml;
		exit ();
	}
}
