1.封装wx.request
const GET = 'GET';
const POST = 'POST';
const PUT = 'PUT';
const FORM = 'FORM';
const DELETE = 'DELETE';const baseURL = 'https://alimini.ck9696.com/wxmall';
// const baseURL = 'http://192.168.0.17:8601/wxmall';
var app = getApp();
function request(method, url, data) {return new Promise(function(resolve, reject) {var header = {'contenst-type': 'application/json','Authorization':wx.getStorageSync('token')};wx.request({url: baseURL + url,method: method,data: method === POST ? JSON.stringify(data) : data,header: header,success(res) {//请求成功//判断状态码---errCode状态根据后端定义来判断if (res.data.code == 0) {resolve(res);} else if (res.data.code == 501) {// 切换到绑定卡片页面// wx.navigateTo({// url: '/pages/bindcard/bindcard'// });} else {//其他异常reject(res);// console.log(res.data.message)wx.showToast({title: res.data.message,icon: 'none',duration: 2000})} },fail(err) {//请求失败console.log(err)}})})
}
2.用法
const API = {getBanner: (data) => request(GET, `/advertising/homeAdvertisingList`),//轮播图getGoods: (data) => request(GET, `/product/home?type=${data}`),//热门商品addTrolley: (data) => request(POST, `/cart/add`,data),//加入购物车
}module.exports = {API: API
}
引入
// 获取数据async getData() {this.setData({bannerlist:(await $api.getBanner()).data.data, // 获取轮播hotlist:(await $api.getGoods(1)).data.data, // 热门商品morelist:(await $api.getGoods(2)).data.data // 获取商品列表},()=> {console.log(this.data);})},sure(){const that = thisif(this.data.flog){$api.addTrolley(that.data.querydata).then(res => {//请求成功// console.log(res)wx.showToast({title: '加入成功',icon: 'success',duration: 2000,success:()=>{that.setData({ show: false,'querydata.number':1});}})$api.getNum().then(res => {//请求成功that.setData({num:res.data.data,})}).catch(err => {// console.log("请求失败")//请求失败})}).catch(err => {//请求失败})}else{var price=that.data.info.price*that.data.querydata.numbervar data={allprice:price,list:[{number:that.data.querydata.number,product:that.data.querydata.productId,picUrl:that.data.lbimgs[0],price:that.data.info.price,productName:that.data.info.productName,}]}wx.navigateTo({url: '/pages/sureorder/sureorder',success: function(res) {res.eventChannel.emit('acceptdata', { data: data })}})}}
3.小程序登录
wx.login({success: res => {// 发送 res.code 到后台换取 openId, sessionKey, unionIdconst that = thiswx.request({url: 'https://alimini.ck9696.com/wxmall/auth', // url: 'http://192.168.0.111:8601/wxmall/auth', data: {code:res.code},header: {'content-type': 'application/json' // 默认值},success (res) {wx.setStorage({key:"token",data:res.data.data.token})that.globalData.iscard = res.data.data.status}})}})
