建立数据表

建立数据请求地址类 

package com.zking.minoa.wxcontroller;import com.zking.minoa.mapper.InfoMapper;
import com.zking.minoa.model.Info;
import com.zking.minoa.util.ResponseUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;
import java.util.List;
import java.util.Map;/*** @Autho donkee* @Since 2022/6/29*/
@RestController
@RequestMapping("/wx/home")
public class WxHomeController {@Autowiredprivate InfoMapper infoMapper;@RequestMapping("/index")public Object index(Info info) {List<Info> infoList = infoMapper.list(info);Map<Object, Object> data = new HashMap<Object, Object>();data.put("infoList",infoList);return ResponseUtil.ok(data);}
}

定义接口类 

package com.zking.minoa;import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@MapperScan("com.zking.minoa.mapper") //指mapper接口所在包
@SpringBootApplication
public class MinoaApplication {public static void main(String[] args) {SpringApplication.run(MinoaApplication.class, args);}}

 前端

先关闭mock

 先编写url地址

 编写utils.js

const formatTime = date => {const year = date.getFullYear()const month = date.getMonth() + 1const day = date.getDate()const hour = date.getHours()const minute = date.getMinutes()const second = date.getSeconds()return `${[year, month, day].map(formatNumber).join('/')} ${[hour, minute, second].map(formatNumber).join(':')}`
}const formatNumber = n => {n = n.toString()return n[1] ? n : `0${n}`
}
/*** 封装微信的request请求*/
function request(url, data = {}, method = "GET") {return new Promise(function (resolve, reject) {wx.request({url: url,data: data,method: method,header: {'Content-Type': 'application/json',},success: function (res) {if (res.statusCode == 200) {resolve(res.data);//会把进行中改变成已成功} else {reject(res.errMsg);//会把进行中改变成已失败}},fail: function (err) {reject(err)}})});
}module.exports = {formatTime,request
}

编写index.js 

// index.js
// 获取应用实例
const app = getApp()
const api=require("../../config/app.js")
const util=require("../../utils/util.js")
Page({data: {imgSrcs:[{"img": ".png","text": "1"},{"img": ".png","text": "2"},{"img": ".png","text": "3"},{"img": ".png","text": "4"},{"img": ".png","text": "5"},{"img": ".png","text": "6"}],lists:[]},// 事件处理函数bindViewTap() {wx.navigateTo({url: '../logs/logs'})},loadMeetInfos(){util.request(api.IndexUrl).then(res=>{console.log(res);this.setData({lists:res.data.infoList})});// let that=this;//  wx.request({//     url: api.IndexUrl,//     dataType: 'json',//     success(res) {//       console.log(res)//       that.setData({//           lists:res.data.data.infoList//       })//     }//   })},loadSwiperImgs(){let that=this;// wx.request({//     url: api.SwiperImgs,//     dataType: 'json',//     success(res) {//       console.log(res)//       that.setData({//           imgSrcs:res.data.images//       })//     }//   })},onLoad() {if (wx.getUserProfile) {this.setData({canIUseGetUserProfile: true})}this.loadSwiperImgs();this.loadMeetInfos();},getUserProfile(e) {// 推荐使用wx.getUserProfile获取用户信息，开发者每次通过该接口获取用户个人信息均需用户确认，开发者妥善保管用户快速填写的头像昵称，避免重复弹窗wx.getUserProfile({desc: '展示用户信息', // 声明获取用户个人信息后的用途，后续会展示在弹窗中，请谨慎填写success: (res) => {console.log(res)this.setData({userInfo: res.userInfo,hasUserInfo: true})}})},getUserInfo(e) {// 不推荐使用getUserInfo获取用户信息，预计自2021年4月13日起，getUserInfo将不再弹出弹窗，并直接返回匿名的用户个人信息console.log(e)this.setData({userInfo: e.detail.userInfo,hasUserInfo: true})}
})

 编写index.wxml

 测试结果

 二.wxs的介绍以及入门 

WXS 代码可以编写在 wxml 文件中的 <wxs> 标签内，或以 .wxs 为后缀名的文件内。

模块
每一个 .wxs 文件和 <wxs> 标签都是一个单独的模块。

每个模块都有自己独立的作用域。即在一个模块里面定义的变量与函数，默认为私有的，对其他模块不可见。

一个模块要想对外暴露其内部的私有变量与函数，只能通过 module.exports 实现。

.wxs 文件
在微信开发者工具里面，右键可以直接创建 .wxs 文件，在其中直接编写 WXS 脚本。
 

在utils里面建立一个文件夹，在文件夹建立wxs文件

wxs文件编写 

// /pages/comm.wxs
function getStateName(state){if(state ==1){return "待审核"}else if(state ==2){return "审核通过"
}else if(state ==3){return "审核不通过"
}else if(state ==4){return "待开会议"
}
return "其他";
}function getNum(canyuze,liexize,zhuchiren){var person = canyuze+ ","+liexize+","+zhuchiren;return person.split(",").length;
}function formatDate(ts, option) {var date = getDate(ts)var year = date.getFullYear()var month = date.getMonth() + 1var day = date.getDate()var week = date.getDay()var hour = date.getHours()var minute = date.getMinutes()var second = date.getSeconds()//获取 年月日if (option == 'YY-MM-DD') return [year, month, day].map(formatNumber).join('-')//获取 年月if (option == 'YY-MM') return [year, month].map(formatNumber).join('-')//获取 年if (option == 'YY') return [year].map(formatNumber).toString()//获取 月if (option == 'MM') return  [mont].map(formatNumber).toString()//获取 日if (option == 'DD') return [day].map(formatNumber).toString()//获取 年月日 周一 至 周日if (option == 'YY-MM-DD Week')  return [year, month, day].map(formatNumber).join('-') + ' ' + getWeek(week)//获取 月日 周一 至 周日if (option == 'MM-DD Week')  return [month, day].map(formatNumber).join('-') + ' ' + getWeek(week)//获取 周一 至 周日if (option == 'Week')  return getWeek(week)//获取 时分秒if (option == 'hh-mm-ss') return [hour, minute, second].map(formatNumber).join(':')//获取 时分if (option == 'hh-mm') return [hour, minute].map(formatNumber).join(':')//获取 分秒if (option == 'mm-dd') return [minute, second].map(formatNumber).join(':')//获取 时if (option == 'hh')  return [hour].map(formatNumber).toString()//获取 分if (option == 'mm')  return [minute].map(formatNumber).toString()//获取 秒if (option == 'ss') return [second].map(formatNumber).toString()//默认 时分秒 年月日return [year, month, day].map(formatNumber).join('-') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}
function formatNumber(n) {n = n.toString()return n[1] ? n : '0' + n
}function getWeek(n) {switch(n) {case 1:return '星期一'case 2:return '星期二'case 3:return '星期三'case 4:return '星期四'case 5:return '星期五'case 6:return '星期六'case 7:return '星期日'}
}module.exports = {getStateName: getStateName,getNum:getNum,formatDate:formatDate
};

在index.wxml中编写数据显示

<!--index.wxml-->
<view><swiper indicator-dots="true" autoplay="true" ><block wx:for="{{imgSrcs}}" wx:key="*text"><swiper-item><image src=" {{item.img}}"></image></swiper-item></block></swiper>
</view><wxs src="/utils/comm.wxs" module="tools" />
<view class="mobi-title"><text class="mobi-icon"></text><text>会议信息</text>
</view>
<block wx:for-items="{{lists}}" wx:for-item="item" wx:key="item.id"><view class="list" data-id="{{item.id}}"><view class="list-img"><image class="video-img" mode="scaleToFill" src="{{item.image !=null ? item.image : '/static/persons/2.jpg'}}"></image></view><view class="list-detail"><view class="list-title"><text>{{item.title}}</text></view><view class="list-tag"><view class="state">{{tools.getStateName(item.state)}}</view><view class="join"><text class="list-num">{{tools.getNum(item.canyuze,item.liexize,item.zhuchiren)}}</text>人报名</view></view><view class="list-info"><text>{{item.location}}</text>|<text>{{tools.formatDate(item.starttime)}}</text></view></view></view>
</block>
<view class="section bottom-line"><text>到底啦</text>
</view>
<!-- <view class="top"></view>
<view class="down">
<view class="list">
<view class="lift"></view>
<view class="right"></view>
</view>
</view> -->
