Analysis of using H5 to call and pay WeChat public account payment

这篇文章主要为大家详细介绍了微信公众号支付H5调用支付,具有一定的参考价值，感兴趣的小伙伴们可以参考一下

最近项目需要微信支付，然后看了下微信公众号支付，虽然不难，但是细节还是需要注意的，用了大半天时间写了个demo，并且完整的测试了一下支付流程，下面分享一下微信公众号支付的经验。

一、配置公众号微信支付  

需要我们配置微信公众号支付地址和测试白名单。

  

比如：支付JS页面的地址为 http://www.xxx.com/shop/pay/
            那此处配置www.xxx.com/shop/pay/

二、开发流程

借用微信公众号支付api(地址 http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=7_4)，我们需要开发的为红色标记出的。如下：

   

三、向微信服务器端下订单

调用统一下单接口，这样就能获取微信支付的prepay_id（http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=9_1）。

在调用该接口前有几个字段是H5支付必须填写的openid

3.1 获取openid

可以通过网页授权形式（http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html）

在微信中发送如下链接     

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx520c15f417810387&redirect_uri=要跳转的下订单的url&response_type=code&scope=snsapi_base&state=123#wechat_redirect

 3.2 后台支付

代码如下，包含预处理订单，支付订单等接口。

四、微信H5调起支付

 这个url需要后台实现，其实现功能如下：
         1、接受微信服务器端发送的支付结果。
         2、向微信服务器发送支付结果

具体 参考微信aip(http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=9_7)
具体代码如下：
4.1、授权向后台发起生成统一下订单页面
wxrepay.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> 
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> 
<% 
 String path = request.getContextPath(); 
 String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; 
 long t = System.currentTimeMillis(); 
%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<title>微信公众号支付</title> 
<link href="../css/css.css?t=<%=t%>" rel="stylesheet" type="text/css">

<body> 
 <p class="index_box">

 <p class="branch_con"> 
 <ul> 
 <li><span class="name">beacon 1分钱 1只</span></li> 
 <li><span class="name">测试支付信息</span></li> 
 </ul> 
 <p class="cz_btn"><a href="javascript:reppay();" class="btn_1">确定购买</a></p> 
 </p> 
 </p> 
 
 <script type="text/javascript" src="../js/common.js?t=<%=t%>"></script> 
 <script type="text/javascript" > 
 
 var code = urlparameter("code"); 
 
 function reppay(){ 
 
 ajaxUtil({}, mainpath+"/pay/wxprepay.shtml?code=" + code, repay); 
 
 } 
 
 function repay(response){ 
 var info = response; 
 var url = "wxpay?appId=" + info.appId + "&timeStamp=" +info.timeStamp + "&nonceStr=" + info.nonceStr + 
  "&pg=" +info.pg + "&signType=" +info.signType + "&paySign=" +info.paySign; 
 
 window.location.href= url + "&showwxpaytitle=1"; 
 } 
 
 
 
 </script> 
</body> 
</html>

首先是请求服务端wxprepay.shml接口，后台向微信支付平台获取支付订单信息，返回前台，wxpay.jsp页面
4.2、确认支付页面

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

 String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; 
 long t = System.currentTimeMillis(); 
%>

五、支付结果

公众号调起效果如下：

支付成功后，微信服务器得到后台的Notify通知后，会发微信说明支付信息，支付凭证如下：

后续会全部更新微信app支付，微信支付退款，微信企业向个人付款，支付宝相关支付。而且会上传全部代码到csdn资源下载处，尽请关注。
