一、前期准备
1.1 数据库准备
创建数据库:
注意:字符集选择utf8mb4,因为可能用存储用户信息,而有些用户包含emoji标签,用该字符集可以进行存储显示。
会议表结构:
1.2 后端数据获取接口编写
package com.ycxw.minoa.wxcontroller;import com.ycxw.minoa.mapper.InfoMapper;
import com.ycxw.minoa.model.Info;
import com.ycxw.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 云村小威* @Since 2023/10/21*/
@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);}
}
1.3 前端配置接口
创建config文件夹 --> api.js文件:
// 以下是业务服务器API地址// 本机开发API地址var WxApiRoot = 'http://localhost:8080/wx/';// 测试环境部署api地址// var WxApiRoot = 'http://192.168.0.101:8070/wx/';// 线上平台api地址//var WxApiRoot = 'https://www.oa-mini.com/wx/';module.exports = {IndexUrl: WxApiRoot + 'home/index', //首页数据接口};
1.4 封装微信的request请求
通过分装微信request请求减少每次都需编写重复的请求代码:
utils/util.js:
/*** 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 = {request
}
二、WXS文件的使用
2.1 WXS简介
WXS(WeiXin Script)是内联在 WXML 中的脚本段。通过 WXS 可以在模版中内联少量处理脚本,丰富模板的数据预处理能力。另外, WXS 还可以用来编写简单的 WXS 事件响应函数。
从语法上看, WXS 类似于有少量限制的 JavaScript 。要完整了解 WXS 语法,请参考WXS 语法参考。
2.2 WXS使用
1、首先在utils目录下创建common.wxs,这个文件存放我们所有的函数方法
//会议人数
function getNum(liexize,canyuze,zhuchiren){var person = liexize+","+canyuze+","+zhuchiren;return person.split(',').length;
}//会议状态
function getStateName(state){if (state == 1){return "待审核"}else if (state == 1){return "审核通过"}else if (state == 1){return "审核不通过"}else if (state == 1){return "待开"}return "其他";
}//导出方法
module.exports = {getStateName:getStateName,getNum:getNum
};
2、将它导入绑定到需要使用的WXML中
<wxs src="/utils/common.wxs" module="tools" />
3、通过定义的module属性值即可调用方法
<view class="state">{{tools.getStateName(xxx数据)}}</view>
三、后台数据交互完整代码
3.1 WXML
<wxs src="/utils/common.wxs" module="tools" />
<view class="indexbg"><swiper autoplay="true" indicator-dots="true" indicator-color="#fff" indicator-active-color="#00f" style="height: 190px;"><block wx:for="{{imgSrcs}}" wx:key="text"><swiper-item><view><image src="{{item.img}}" class="swiper-item" /></view> </swiper-item></block></swiper><view class="mobi-title"><text class="mobi-text">会 议 信 息</text></view><block wx:for-items="{{lists}}" wx:for-item="item" wx:key="item.id" class="bg"><view class="list" data-id="{{item.id}}"><view class="list-img"><image class="video-img" mode="scaleToFill" src="{{item.image != null ? item.image : '/static/images/avatar.png'}}"></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>{{item.starttime}}</text></view></view></view></block><view class="section"><text>到底啦</text></view>
</view>
3.2 JS
// index.js
// 获取应用实例
const app = getApp()
const api = require("../../config/api")
const util = require("../../utils/util.js")Page({data: {imgSrcs: [ {"img": "https://1.s91i.faiusr.com/4/AFsI4uYPEAQYACDw69bhBSjulrWKBTDABzicBA!800x800.png?_tm=3&v=1556100764632","text": "1"},{"img": "https://img.zcool.cn/community/01e71e61e7c7ba11013e8cd0236304.jpg?x-oss-process=image/auto-orient,1/resize,m_lfit,w_1280,limit_1/sharpen,100","text": "2"},{"img": "https://ts1.cn.mm.bing.net/th/id/R-C.022f2e37a033ca3c5754d2f32e8132a1?rik=9ysyMcx6nMOilg&riu=http%3a%2f%2fres.picxiaobai.com%2ftxb%2ftemplate%2fpre%2f20200517%2fd7580b5326b45a612dbf2c1904bc6ca2.jpg%3fv%3d1589705812%26x-oss-process%3dimage%2fresize%2cw_500&ehk=mHQV45sPbW8QB5iv%2ftSXZeasTn4bN6d%2bdLOtwiOYpl8%3d&risl=&pid=ImgRaw&r=0&sres=1&sresct=1","text": "3"},{"img": "https://bpic.588ku.com/Templet_origin_pic/05/08/59/20760ea806f4a490f73c577d69e8ffe8.jpg","text": "4"},{"img": "https://img.tukuppt.com/ad_preview/00/10/75/5d78cd9a6a9b4.jpg!/fw/780","text": "5"},{"img": "https://1.s91i.faiusr.com/4/AFsI4uYPEAQYACDv69bhBSiCruq3BTDABzicBA!800x800.png?v=1556100745578","text": "6"}],lists: []},// 事件处理函数bindViewTap() {wx.navigateTo({url: '../logs/logs'})},//首页会议信息的ajaxloadMeetingInfos() {util.request(api.IndexUrl).then(res => {this.setData({lists: res.data.infoList})})},onLoad() {if (wx.getUserProfile) {this.setData({canIUseGetUserProfile: true})}this.loadMeetingInfos();}})
