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} = datawx.requestPayment({timeStamp,nonceStr,package: data.package,signType,paySign,success() {console.log('支付成功');wx.showToast({title: '支付成功',icon: 'success',duration: 1500,});setTimeout(() => {wx.redirectTo({url: '/pages/home/home',})}, 1500)},fail() {console.log('支付失败');wx.showToast({title: '支付失败',icon: 'error',duration: 1500,});},})} catch (err) {console.log(err)wx.showToast({title: err,icon: 'error',duration: 1500,});// Dialog.alert({// title: "请求错误",// message: err,// confirmButtonColor: "#F16E30",// context: this // 添加this指向// });}}).catch((err) => {console.log(err, 10)}).finally(() => {// this.setData({// btnLoading: false// })wx.hideLoading()// resolve()})
