This article is divided into the following three parts:

WeChat payment directory setting

Delivery interface adjustment

Adjustment of rights protection interface and alarm interface

1. WeChat payment directory setting

The setting of WeChat payment URL is closely related to the adjustment of WeChat payment. The several URL settings we use here are as follows:

Rights notification URL: http://www.fangbei.org/wxpay/rights/index.php
Alarm notification URL: http://www.fangbei.org/wxpay /alarm/index.php

2. Adjustment of the shipping interface

Before adjusting the shipping interface, the user needs to have a transaction before sending, so first Complete a jsapi payment, the code is as follows,

<?php
include_once("WxPayHelper.php");
$commonUtil = new CommonUtil();
$wxPayHelper = new WxPayHelper();
$wxPayHelper->setParameter("bank_type", "WX");
$wxPayHelper->setParameter("body", "方倍微信支付测试");
$wxPayHelper->setParameter("partner", PARTNERID);
$wxPayHelper->setParameter("out_trade_no", $commonUtil->create_noncestr());
$wxPayHelper->setParameter("total_fee", "1");
$wxPayHelper->setParameter("fee_type", "1");
$wxPayHelper->setParameter("notify_url", "http://www.fangbei.org/wxpay/notify/index.php");
$wxPayHelper->setParameter("spbill_create_ip", $_SERVER[&#39;REMOTE_ADDR&#39;]);
$wxPayHelper->setParameter("input_charset", "GBK");
$biz_package=$wxPayHelper->create_biz_package();
?>
<html>
<meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0,maximum-scale=1.0,user-scalable=no;">
<script language="javascript">
    function callpay()
    {
        WeixinJSBridge.invoke(&#39;getBrandWCPayRequest&#39;,<?php echo $biz_package;?>,function(res){
        WeixinJSBridge.log(res.err_msg);
        alert(res.err_code+res.err_desc+res.err_msg);
        });
    }
</script>
<body>
    <button type="button" onclick="callpay()">方倍微信支付测试</button>
</body>
</html>
