WeChat public account payment

1. Use jssdk to call WeChat payment, please check the development documentation for details;

The vuex used is in mutations

    wechatPay (state, data) {
         state.payObject = data
         console.log('微信支付开始请求')
         if (wechat) {
           wx.chooseWXPay({
             timestamp: state.payObject.timeStamp, // 支付签名时间戳
             nonceStr: state.payObject.nonceStr, // 支付签名随机串，不长于 32 位
             package: state.payObject.package, // 统一支付接口返回的prepay_id参数值
             signType: state.payObject.signType, // 签名方式使用新版支付需传入'MD5'
             paySign: state.payObject.paySign, // 支付签名
             success: function (res) {
               alert('成功')
               alert(JSON.stringify(res))
             },
             cancel: function (res) {
               alert('已取消支付')
               alert(JSON.stringify(res))
             },
             fail: function (res) {
               alert(JSON.stringify(res))
             }
           })
         }
       }

Copy after login

In commit

    // 存储微信支付数据data
    let data = res.body.data
    console.log('即将跳转微信支付')
    this.$store.commit({
        timeStamp: data.timeStamp,
        nonceStr: data.nonceStr,
        type: 'wechatPay',
        package: data.package,
        signType: data.signType,
        paySign: data.paySign
    })

Copy after login

on the payment page. 2. After clicking the completion button for payment, the front-end will receive the return value of JavaScript;

3. The background will receive a payment success callback notification from the WeChat open platform

Step on the Pit

1. chooseWXPay:fail, the permission value is offline verifying

这是因为不能在在微信开发者工具上测试，需要真机测试

Copy after login

2. chooseWXPay:fail

需要配置正确的支付授权目录，vue的单页应用直接配置为域名就行。

其他需要配置为调用支付的上一级目录，以/结束

Copy after login

3. Order account and payment Account inconsistency

需要后台看一下openId配置

Copy after login
