微信app支付详细教程
微信支付作为三大支付之一,越来越多的客户要求产品中添加微信支付 但是网上能找到可用的demo很少
所以写一篇自己写微信支付的过程,希望能给有需要的开发者一点帮助。
下面让我们来进入正题
1准备工作
首先得去微信开放平台申请app支付权限 当申请成功后会收到一封邮件 这里面有个商店号 MCH_ID 和PARTNER_ID 注意这俩 其实是一样的,都是商店号,但是
通过上图我们可以看到 不同接口 对应的字段并不一样 (有意思吗 就不能统一一下)但其实都是一个商店号
然后我们还需要拿到一些key值 下面代码有介绍 就不一一说来源了
拿到这些值之后我们就可以进行下一步了
2写支付逻辑
我写的代码如下 关键点都加上了注解
@Api(tags = {"支付接口"})
@RestController
@RequestMapping(value = "weixinMobile")
public class WeixinMobilePayController {
private static final Logger logger = LoggerFactory.getLogger(WeixinMobilePayController.class);
@RequestMapping(value="dop",method=RequestMethod.POST)
public JsonBack dopay(HttpServletRequest request, JsonBack jsonBack,HttpServletResponse response,String membertoken,int num,String id) throws Exception {
Member mem= MemberServiceImp.loginMemberMap.get("token");
if(mem.getMemberToken().equals(membertoken)){
MemberLevel level = memberLevelService.getMemberLevelById(id);
int x = Integer.parseInt(level.getLevelMoney());
int cc=x * num*100;//微信以分为单位,如果数据库里面的价格没扩大100的话这里要乘以100
String total_fee =cc+"";
String body=ConstantUtil.BODY;
String mch_id=ConstantUtil.MCH_ID;
String currTime = PayCommonUtil.getCurrTime();
String strTime = currTime.substring(8, currTime.length());
String strRandom = PayCommonUtil.buildRandom(4) + "";
String nonce_str = strTime + strRandom;
String notify_url=ConstantUtil.NOTIFY_URL;//回调地址 必须能直接访问 不是二级域名也可以
String out_trade_no=String.valueOf(UUID.next()); // 订单号
String timestamp=WXUtil.getTimeStamp();
SortedMap<Object, Object> packageParams = new TreeMap<Object, Object>();
packageParams.put("appid",ConstantUtil.APP_ID);
packageParams.put("mch_id",mch_id);
packageParams.put("nonce_str",nonce_str);
packageParams.put("body",body);// 商品描述
packageParams.put("out_trade_no", out_trade_no);// 商户订单号
packageParams.put("total_fee", total_fee);// 总金额
String addr = AddressUtils.getIpAddr(request);
packageParams.put("spbill_create_ip", addr);// 发起人IP地址
packageParams.put("notify_url", notify_url);// 回调地址
packageParams.put("trade_type", "APP");// 交易类型
packageParams.put("time_start",timestamp);
String sign = PayCommonUtil.createSign("UTF-8", packageParams,ConstantUtil.APP_KEY);
packageParams.put("sign", sign);// 签名
String requestXML = PayCommonUtil.getRequestXml(packageParams);
String resXml = HttpUtil.postData(ConstantUtil.NOTIFY_URL, requestXML);
Map map = XMLUtil.doXMLParse(resXml);
String returnCode = (String) map.get("return_code");
String returnMsg = (String) map.get("return_msg");
logger.info("result:"+returnMsg);
if("SUCCESS".equals(returnCode)){
String resultCode = (String) map.get("result_code");
String prepay_id = (String) map.get("prepay_id");
String noncestr=(String) map.get("nonce_str");
if("SUCCESS".equals(resultCode)){
System.out.println("获取prepay_id成功"+prepay_id);//必须获取到这个prepay_id才算微信认可了你的第一次签名
//这里写预下单业务逻辑
SortedMap<Object, Object> packageParam = new TreeMap<Object, Object>();
// ConfigUtil.commonParams(packageParams);
packageParam.put("appid",ConstantUtil.APP_ID);
packageParam.put("partnerid",mch_id);
packageParam.put("noncestr",noncestr);
packageParam.put("prepayid",prepay_id);// 商品描述
packageParam.put("package", "Sign=WXPay");// 商户订单号
packageParam.put("timestamp",timestamp);
String sign1 = PayCommonUtil.createSign("UTF-8", packageParam,ConstantUtil.APP_KEY);//这里是二次签名 前台要拿到去调起微信支付,如果这个错了的话会在前台报签名错误
map.put("partnerid", mch_id);
map.put("timestamp", timestamp);
map.put("package","Sign=WXPay");
map.put("retcode", "0");
map.put("sign", sign1);
jsonBack = new JsonBack(true, "success", map);
}}
}else{
jsonBack = new JsonBack(false, "token不一致", null);
}
return jsonBack;
}
3 写回调逻辑
微信会根据你的回调地址去请求回调的action 并且地址必须是网络地址 能直接访问 而且不能携带参数
代码如下
@RequestMapping(value="WXP",method=RequestMethod.POST)
public void WXPayBack(HttpServletRequest request, HttpServletResponse response){
String resXml = "";
Member mem= MemberServiceImp.loginMemberMap.get("token");
try {
//解析XML
Map<String, String> map = MobileUtil.parseXml(request);
String return_code = map.get("return_code");//状态
String out_trade_no = map.get("out_trade_no");//订单号
if (return_code.equals("SUCCESS")) {
if (out_trade_no != null) {
//处理订单逻辑
这里面可以根据订单号来查询到付款买的什么
然后在预订单里加一个是否付款的状态来限制只能执行一次业务逻辑
否则就需要返回给微信一个success
resXml = "<xml><return_code>SUCCESS</return_code><return_msg>OK</return_msg></xml>";
} catch (Exception e1) {
// TODO Auto-generated catch block
logger.warn("新增服务失败");
}
}
else{
logger.warn("该用户已经买过金卡");
}
}else{
logger.info("已经购买会员完成");
}
}else{
//logger.warn("[payPage]根据id查询等级没有查询到记录,levelId="+levelId);
}
}else{
logger.info("callback fail:{}",out_trade_no);
resXml = "<xml>" + "<return_code><![CDATA[FAIL]]></return_code>" + "<return_msg><![CDATA[报文为空]]></return_msg>" + "</xml> ";
}
} catch (Exception e) {
logger.error("callback fail",e);
resXml = "<xml>" + "<return_code><![CDATA[FAIL]]></return_code>" + "<return_msg><![CDATA[报文为空]]></return_msg>" + "</xml> ";
}
}
