微信小程序OA会议系统数据交互

前言

经过我们所写的上一文章：微信小程序会议OA系统其他页面-CSDN博客

在我们的是基础面板上面，可以看到出来我们的数据是死数据，今天我们就完善我们的是数据

后台

在我们去完成项目之前我们要把我们的项目后台准备好资源我放在我资源中，大家可以用于参考，也可以去使用

pom.xml

这个是我们用来导入的

<?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>

appliation.yml

这个应用于生成mapper接口，model实体类以及mapper映射文件

spring:datasource:#type连接池类型 DBCP,C3P0,Hikari,Druid,默认为Hikaritype: com.zaxxer.hikari.HikariDataSourcedriver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://localhost:3306/mybatis_oapro?useUnicode=true&characterEncoding=UTF-8&useSSL=falseusername: rootpassword: 123456

@MapperScan("com.zking.minoa.mapper") //指mapper接口所在包

前端

在我们使用我们的微信小程序开发之前我们可以不我们的之前所配置的Mock等等关闭

index.js

  loadMeetingInfo(){let that=this;wx.request({url: api.IndexUrl,dataType: 'json',success(res) {console.log(res)that.setData({lists:res.data.data.infoList})}})},

在我们添加后，我们要在生命周期函数加入以下代码

  onLoad(options) {// this.loadSwiperImgs();// this.loadMeetingInfos();this.loadMeetingInfo();//首页会议信息},

index.wxml
 

 <image class="video-img" mode="scaleToFill" src="{{item.image != null ? item.image : '/static/persons/会议桌.jpg'}}"></image>

效果：

request

util.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
}

头部引用util

const util = require("../../utils/util.js")

方法 

loadMeetingInfo(){util.request(api.IndexUrl).then(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//       })//     }//   })},

WXS如何使用

会议状态

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。如下：

comm.wxs：

// /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"
}
module.exports = {getStateName: getStateName
};

引入wxs

在我们的index.wxml中引入wxs，代码如下：

<wxs src="/utils/comm.wxs" module="tools" />

将index.wxml中class为state的view代码块改为以下代码

<view class="state">{{tools.getStateName(item.state)}}</view>

统计参会人

在我们的comm.wxs中加入以下代码

<view class="join"><text class="list-num">{{tools.getNum(item.canyuze,item.liexize,item.zhuchiren)}}</text>人报名</view>

function getNum(canyuze,liexize,zhuchiren){var person = canyuze + "," + liexize + "," + zhuchiren;return person.split(",").length;
}
module.exports = {getStateName: getStateName,getNum: getNum
};

然后在index.wxml中class为list-num的view代码块改为以下代码

<view class="join"><text class="list-num">{{tools.getNum(item.canyuze,item.liexize,item.zhuchiren)}}</text>人报名</view>

处理时间

在comm.wxs中加入时间处理代

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'}}

导出

module.exports = {getStateName: getStateName,getNum: getNum,formatDate: formatDate
};

在index.wxml中class为list-info的view代码块代码改为以下代码

<view class="list-info"><text>{{item.location}}</text>|<text>{{tools.formatDate(item.starttime)}}</text></view>
