一.与后台数据进行交互&request封装
后台准备
pom.xml文件编写
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.6.2</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.zking</groupId> <artifactId>minoa</artifactId> <version>0.0.1-SNAPSHOT</version> <name>minoa</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> <fastjson.version>1.2.70</fastjson.version> <jackson.version>2.9.8</jackson.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.44</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>${fastjson.version}</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <excludes> <exclude> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </exclude> </excludes> </configuration> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <dependencies> <!--使用Mybatis-generator插件不能使用太高版本的mysql驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> </dependencies> <configuration> <overwrite>true</overwrite> </configuration> </plugin> </plugins> </build> </project>
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 { @Autowired private 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); } }
测试结果
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() + 1 const 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": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner1.png", "text": "1" }, { "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner2.png", "text": "2" }, { "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner3.png", "text": "3" }, { "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner4.png", "text": "4" }, { "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner5.png", "text": "5" }, { "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner6.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 标签内，或以 .wxs 为后缀名的文件内。
模块
每一个 .wxs 文件和 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() + 1 var 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> -->
