小程序支付（前端）

前端只需要调用 wx.requestPayment(Object object)
文档

参考代码

      const openId = wx.getStorageSync('openId')
        payOrder({
            payId: this.data.resData.payId,
            openId
        }).then((res) => {
            console.log(2222, res);
            try {
                const data = JSON.parse(res.res)
                console.log(22, data)
                const {
                    timeStamp,
                    nonceStr,
                    signType,
                    paySign
                } = data

                wx.requestPayment({
                    timeStamp,
                    nonceStr,
                    package: data.package,
                    signType,
                    paySign,
                    success() {
                        console.log('支付成功');
                        wx.showToast({
