Schematic diagram of an asynchronous operation code for online Banking

1. With regard to the operation of asynchronous feedback, this is necessary because sometimes, if the user suddenly breaks the net or something, it will not result in data anomalies, no feedback to the successful information.
So this operation needs to be asynchronous.
If the normal situation, is to take the process of synchronization, and then the net will be around every three minutes feedback an asynchronous request, only the feedback value is true to modify the order information, the basic value and synchronization are similar.

2. Learn about the written operation.
① in the main.php file, configure an asynchronous return path

② in the Unionpayproxy.php folder, add the URL of the asynchronous notification on the original basis and initialize it to the Remark2 field.

③ in the Unionpayservice page, the Remark2 field is initialized individually, if any, is

if($key‘remark2‘){    //在remark2这个字段配置一个异步通知的url注意在value里面要加上中括号    $sHtml.=‘<input  type="hidden"  name="remark2" value="[url:=‘.$val.‘]">‘;}

To add the above fields, the URL there to add brackets, be sure to follow the above format to assign values

④ add a corresponding method in the directory where I correspond to the asynchronous notification, and the exact wording is the same as the synchronization
/**
* UnionPay returns the display page asynchronously
* @desc asynchronous notification to pay "statement"
* @return Boolean
* @author Xcz <2015-7-28>
