thinkphp微信支付成功后回调函数设置【小结】

这两天要小程序用到微信支付功能，应用thinkphp3.2的，在集成回调通知处理结果的时候，一直卡住了，不知道怎么写，在经过了查找N多资料后，终于皇天不负有心人，找到了解决方法，下面代码经测试通过，确信可用：

public function notify_url()
    {        
        $filename = './Public/file00.txt'; 
        file_put_contents($filename, date("Y-m-d H:i:s",NOW_TIME));
        try
        {
            $filename = './Public/file01.txt';
            file_put_contents($filename, 'file01');
            /*
            $notify = new OrderNotifyCallBack();
            $notify->Handle(false);
            */
            Vendor("WxpayAPI_php_v3.lib.WxPay","",".Api.php");
            Vendor("WxpayAPI_php_v3.lib.WxPay","",".Data.php");
            Vendor("WxpayAPI_php_v3.example.log");
            
            
            $handle=new \CLogFileHandler('./Public/wxlog.txt');
            //$log=\Logwx::Init($handle);
            $xml = $GLOBALS['HTTP_RAW_POST_DATA'];//获取数据
            //$log->INFO('xml:'.$xml);
            $filename = './Public/file02.txt';
            file_put_contents($filename, $xml); 
            
            $wxpay=new \WxPayApi();
            $notify=new \WxPayNotifyReply();
            $result=\WxPayResults::Init($xml);//获取数据并转换为数组
            if ($result['return_code']=='SUCCESS' && $result['result_code']=='SUCCESS')
            {
                //此字段是通信标识，非交易标识，交易是否成功需要查看result_code来判断
                ///-------------------------------------------------begin修改订单状态
                $openid = $result["openid"];
                $product_id = $result["out_trade_no"]; 
                $tarnsactionId=$result["transaction_id"];
                $res=true;//订单处理结果
                ///-------------------------------------------------end 修改订单状态 
                
                //TODO:进行数据库操作的业务逻辑处理,假设其成功与否的数据为$res 
                $filename = './Public/file03.txt';
                file_put_contents($filename, "file03"); 
                if ($res)
                {
                    //$log->INFO('订单:'.$result['out_trade_no'].'支付成功');
                    $notify->SetReturn_code('SUCCESS');
                    $notify->SetReturn_msg('OK');
                    $notify->SetSign();
                    $filename = './Public/file04.txt';
                    file_put_contents($filename, "file04:SUCCESS");
                }
                else
                {
                    //$log->ERROR('微信支付失败');
                    $notify->SetReturn_code('FAIL');
                    $notify->SetReturn_msg('客户服务器错误');                    
                    $filename = './Public/file04.txt';
                    file_put_contents($filename, "file04:客户服务器错误");
                }
            }
            else
            {
                //$log->ERROR('微信回调返回错误');
                $notify->SetReturn_code('FAIL');
                $notify->SetReturn_msg('微信支付失败');                
                $filename = './Public/file04.txt';
                file_put_contents($filename, "file04:微信回调返回错误");
            }
            //返回微信端
            $wxpay->replyNotify($notify->ToXml());
            
            $filename = './Public/file06.txt';
            file_put_contents($filename, 'file06');
        }
        catch(Exception $e)
        {
            //捕获异常 
            $filename = './Public/file07.txt';
            file_put_contents($filename, 'Message: ' .$e->getMessage() );
        }
        
    }

这里放弃了，微信支付sdk中的继承WxPayNotify通知类，直接调用

Vendor("WxpayAPI_php_v3.lib.WxPay","",".Api.php");
Vendor("WxpayAPI_php_v3.lib.WxPay","",".Data.php");

处理异步通知消息。
