小程序支付，没有封装支付代码：直接上一段可用的流程代码吧：
微信小程序支付官网文档有详细的说明，这里我就不再赘述啦：
客户端js:
wx.request({ url:\'https://www.xxxx.com/order/store\',//改成你自己的链接 header:{ \'Content-Type\':\'application/x-www-form-urlencoded\' }, method:\'POST\', success:function(res){ console.log(res.data); console.log(\'调起支付\'); wx.requestPayment({ \'timeStamp\': res.data.timeStamp, \'nonceStr\': res.data.nonceStr, \'package\': res.data.package, \'signType\':\'MD5\', \'paySign\': res.data.paySign, \'success\':function(res){ console.log(\'success\'); wx.showToast({ title:\'支付成功\', icon:\'success\', duration:3000 }); }, \'fail\':function(res){ console.log(\'fail\'); }, \'complete\':function(res){ console.log(\'complete\'); } }); }, fail:function(res){ console.log(res.data) } });
后端部分：laravel5:<?php

代码没有完美封装，博友们如果有一套好的封装，请留下共享地址哈啊
