因为人事档案具备涉密性，所以本利用没有应用后盾服务，全副性能都在APP本地实现。
开发工具采纳 APICloud Studio3，基于VSCode的（PS：比基于Atom的autio2好用太多）；
数据库采纳sqllite，没有应用UI框架，集体感觉AVM自身反对的flex布局配合自写CSS款式，齐全能够实现市面上所有的ＵＩ框架的元素，这个取决于集体功力。

用到的模块
我的项目文件目录
援用一下官网的对于目录构造的介绍
四、性能开发详解
1、首页导航
零碎首页应用tabLayout，能够将相干参数配置在JSON文件中，再在config.xml中将content的值设置成该JSON文件的门路。如果底部导航没有非凡需要这里强烈建议大家应用tabLayout为APP进行布局，官网曾经将各类手机屏幕及不同的分辨率进行了适配，免去了很多对于适配方面的问题。
app.json文件内容，对于json文件的命名是没有限度的，我习惯用app。
{ "name": "root", "textOffset": 6, "color": "#999999", "selectedColor": "#006aff", "scrollEnabled": false, "hideNavigationBar": false, "bgColor": "#fff", "navigationBar": { "background": "#006aff", "shadow": "rgba(0,0,0,0)", "color": "#fff", "fontSize": 18, "hideBackButton": true }, "tabBar": { "background": "#fff", "shadow": "#eee", "color": "#5E5E5E", "selectedColor": "#006aff", "textOffset": 3, "fontSize": 11, "scrollEnabled": true, "index": 1, "preload": 0, "frames": [ { "title": "编制状况", "name": "home", "url": "./pages/records/organ" }, { "title": "人员花名册", "name": "course", "url": "./pages/person/organ" }, { "title": "集体核心", "name": "user", "url": "./pages/main/main" } ], "list": [ { "text": "编制", "iconPath": "./image/authoried-o.png", "selectedIconPath": "./image/authoried.png" }, { "text": "人员", "iconPath": "./image/person-o.png", "selectedIconPath": "./image/person.png" }, { "text": "我的", "iconPath": "./image/user-o.png", "selectedIconPath": "./image/user.png" } ] } }2、列表显示及分页
通过上拉刷新和下拉操作，配合JS办法实现分页查问性能。
<template name='list'> <scroll-view scroll-y class="main" enable-back-to-top refresher-enabled refresher-triggered={refresherTriggered} onrefresherrefresh={this.onrefresherrefresh} onscrolltolower={this.onscrolltolower}> <view class="item-box"> <view class="item" data-id={item.id} v-for="(item, index) in personList" tapmode onclick="openTab"> <image class="avator" src={item.photo} mode="widthFix"></image> <text class="item-title">{item.name}</text> <text class="item-sub-title">{item.nation}</text> </view> </view> <view class="footer"> <text class="loadDesc">{loadStateDesc}</text> </view> </scroll-view></template><script> import $util from "../../utils/utils.js" export default { name: 'list', data() { return{ personList:[], skip: 0, refresherTriggered: false, haveMoreData: true, loading: false, organid:0 } }, computed: { loadStateDesc(){ if (this.data.loading || this.data.haveMoreData) { return '加载中...'; } else if (this.personList.length > 0) { return '没有更多啦'; } else { return '临时没有内容'; } } }, methods: { apiready(){ this.data.organid = api.pageParam.id; this.loadData(false); //更换头像 api.addEventListener({ name: 'setavator' }, (ret, err) => { this.loadData(); }); //新增人员信息 api.addEventListener({ name: 'addperson' }, (ret, err) => { this.loadData(); }); //删除人员信息 api.addEventListener({ name: 'delperson' }, (ret, err) => { this.loadData(); }); if(api.getPrefs({sync: true,key: 'role'})=='99'){ //增加编辑按钮 api.setNavBarAttr({ rightButtons: [{ text: '新增' }] }); //监听右上角按钮点击事件 api.addEventListener({ name: 'navitembtn' }, (ret, err) => { if (ret.type == 'right') { $util.openWin({ name: 'personadd', url: 'personadd.stml', title: '新增人员信息', pageParam:{ organid:this.data.organid } }); } }); } }, loadData(loadMore) { if (this.data.loading) { return; } api.showProgress(); this.data.loading = true; var limit = 15; var skip = loadMore?(this.data.skip+1)*limit:0; // console.log('select id,name,grade,sex,nation,photo from authority where organ = '+this.data.organid+' order by id limit '+limit+' offset '+skip); var db = api.require('db'); db.selectSql({ name: 'doc', sql: 'select id,name,grade,sex,nation,photo from authorized where organ = '+this.data.organid+' order by id limit '+limit+' offset '+skip }, (ret, err)=> { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { let records = ret.data; this.data.haveMoreData = records.length == limit; if (loadMore) { this.data.personList = this.data.personList.concat(records); } else { this.data.personList = records; } this.data.skip = skip; } else { this.data.recordsList = records; api.toast({ msg:err.msg }) } this.data.loading = false; this.data.refresherTriggered = false; api.hideProgress(); }); }, /*下拉刷新页面*/ onrefresherrefresh(){ this.data.refresherTriggered = true; this.loadData(false); }, onscrolltolower() { if (this.data.haveMoreData) { this.loadData(true); } }, openTab(e){ let id = e.currentTarget.dataset.id; $util.openWin({ name: "personinfo", url: 'personinfo.stml', title: '人员信息', pageParam:{ id:id } }); } } }</script>3、表单提交
采纳AVM自带的from控件，通过onsubmit进行数据提交
4、头像图片上传及base64转码
因为是本地sqllite数据库，人员头像图片须要转成base64编码存储到数据库中。通过官网模块trans进行图片转码操作。
<image class="avator" src={this.data.src} mode="widthFix" onclick="setavator"></image> setavator(){ api.actionSheet({ cancelTitle: '勾销', buttons: ['拍照', '关上相册'] }, (ret, err) => { if (ret.buttonIndex == 3) { return false; } var sourceType = (ret.buttonIndex == 1) ? 'camera' : 'album'; api.getPicture({ sourceType: sourceType, allowEdit: true, quality: 20, destinationType:'url' }, (ret, err) => { if (ret && ret.data) { var trans = api.require('trans'); trans.decodeImgToBase64({ imgPath: ret.data }, (ret, err) => { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { let b64 = "data:image/jpeg;base64,"+ret.base64Str; this.data.src = b64; } else { api.toast({ msg:'照片上传失败，请从新抉择！' }) } }); } }); }); },5、sqllite数据库 db模块
因为数据库文件须要存储的利用安装文件中，所有须要官网fs模块配合应用来进行数据库文件的操作。
copyDB(){ var fs = api.require('fs'); fs.copyTo({ oldPath: 'widget://db/doc.db', newPath: 'fs://db' }, function(ret, err) { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { // console.log(JSON.stringify(ret)); api.toast({ msg:'拷贝数据库胜利!' }) } else { // console.log(JSON.stringify(err)); api.toast({ msg:JSON.stringify(err) }) } }); }, openDB(){ var db = api.require('db'); db.subfile({ directory:'fs://db' }, (ret, err)=> { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { // console.log(JSON.stringify(ret)); //关上数据库 db.openDatabase({ name: 'doc', path: ret.files[0] }, (ret, err)=> { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { // console.log(JSON.stringify(ret)); api.toast({ msg:'关上数据库胜利！' }) } else { // console.log(JSON.stringify(err)); api.toast({ msg:JSON.stringify(err) }) } }); } else { // console.log(JSON.stringify(err)); api.toast({ msg:JSON.stringify(err) }) } }); }, closeDB(){ var db = api.require('db'); db.closeDatabase({ name: 'doc' }, function(ret, err) { if (ret.status) { console.log(JSON.stringify(ret)); api.toast({ msg:'敞开数据库胜利' }) } else { // console.log(JSON.stringify(err)); api.toast({ msg:JSON.stringify(err) }) } }); }, updateDB(){ var fs = api.require('fs'); var db = api.require('db'); db.closeDatabase({ name: 'doc' }, (ret, err) => { if (ret.status) { //拷贝文件 fs.copyTo({ oldPath: 'widget://doc.db', newPath: 'fs://db/' }, (ret, err) => { if (ret.status) { db.subfile({ directory:'fs://db' }, (ret, err)=> { if(ret.status){ //关上数据库 db.openDatabase({ name: 'doc', path: ret.files[0] }, (ret, err)=> { if (ret.status) { api.toast({ msg:'数据库更新胜利！' }) } else { api.toast({ msg:JSON.stringify(err) }) } }); } else{ api.toast({ msg:JSON.stringify(err) }) } }) } else { api.toast({ msg:JSON.stringify(err) }) } }); } else { api.toast({ msg:JSON.stringify(err) }) } }); },6、语音播报性能
采纳官网提供的IFLyVoice模块，须要留神的是，根底资源文件和发音人资源文件（.jet文件）须要到科大讯飞开发者平台进行下载导入的我的项目中。还有对数字的解读不是准确，尤其是年份，最好不要用数字，而是用中文。
//增加朗诵按钮 api.setNavBarAttr({ rightButtons: [{ text: '朗诵' }] }); //监听右上角按钮点击事件 api.addEventListener({ name: 'navitembtn' }, (ret, err) => { // console.log(JSON.stringify(this.data.info)); if (ret.type == 'right') { var IFlyVoice = api.require('IFlyVoice'); IFlyVoice.initSpeechSynthesizer((ret)=>{ // console.log(JSON.stringify(ret)); }); IFlyVoice.startSynthetic({ text:this.data.info, commonPath_Android:'widget://res/android/common.jet', pronouncePath_Android:'widget://res/android/xiaoyan.jet', pronounceName:'xiaoyan', speed:40 },(ret,err)=>{ // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { // console.log('合成胜利'); } else { // console.log(JSON.stringify(err)); } }); } });7、手势密码保护
手势密码保护因为官网模块存在款式问题，及原生模块存在遮罩问题，所以采纳了平台上提供的H5模块。APICloud弱小之处在这里进行了酣畅淋漓的体现，通过AVM及原生模块无奈实现的性能，能够再用H5的形式来实现！牛逼！！！！，通过设置全局变量来记录是否已设置手机明码，每次利用启动通过这个变量来判断是否开启手势密码保护。
this.data.islock =api.getPrefs({sync: true,key: 'islock'}); if(this.data.islock=='Y'){ api.openFrame({ name: 'h5lock', url:'../../html/h5lock.html' }) } else{ api.toast({ msg:'您还没有设置手势明码，为了数据安全，请尽快设置。' }) }<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no"> <title>H5lock</title> <style type="text/css"> body { text-align: center;

登录胜利之后，在集体核心来设置手势明码。可通过参数设置来初始化明码强度。
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no"> <title>H5lock</title> <style type="text/css"> body { text-align: center; background-color: #000000; } .title { /*color: #87888a;*/ margin-top: 85px; font-size: 20px; font-weight:lighter; } .reset{ position: relative; top: 200px; font-size: 20px; text-align: center; } </style></head><body><script type="text/javascript" src="../script/setH5lock.js"></script><script type="text/javascript"> var opt = { chooseType: 3, // 3 , 4 , 5, width: 300, // lock wrap width height: 300, // lock wrap height container: 'element', // the id attribute of element inputEnd: function (psw){} // when draw end param is password string } var lock = new H5lock(opt); lock.init();</script></body></html>9、批改明码
零碎默认设定了用户的初始密码，用户登录零碎后会提醒进行明码批改，批改后的明码进行了MD5加密，因为没有后盾零碎，所以明码的MD5加密，采纳了JS来进行加密。通过开发工具调试控制台装置js插件
装置胜利之后会在文件目录中显示
而后在用的中央间接引入即可。
import $md5 from '../../node_modules/js-md5/build/md5.min.js' var db = api.require('db'); db.executeSql({ name: 'doc', sql: "update user set password = '"+ md5(ret.text) +"' where id = 1" }, (ret, err)=> { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { api.alert({ title: '音讯揭示', msg: '明码批改胜利，请从新登陆', }, (ret, err) => { //革除用户信息 api.removePrefs({ key: 'username' }); api.removePrefs({ key: 'userid' }); api.removePrefs({ key: 'password' }); $util.openWin({ name: 'login', url: '../main/login.stml', title: '', hideNavigationBar:true }); }); } else { api.toast({ msg:JSON.stringify(err) }) } });10、封装工具类插件 utils.js
在须要用到插件中通用办法的中央，间接援用即可。
import $util from "../../utils/utils.js"const $util = { openWin(param){ var param = { name: param.name, url: param.url, title: param.title||'', pageParam: param.pageParam||{}, hideNavigationBar: param.hideNavigationBar || false, navigationBar:{ background:'#1492ff', shadow: '#fff', color: '#fff' } }; if (this.isApp()) { api.openTabLayout(param); } else { api.openWin(param); } }, isApp(){ if (api.platform && api.platform == 'app') { return true; } return false; }, fitRichText(richtext, width){ var str = `<img style="max-width:${width}px;"`; var result = richtext.replace(/\<img/gi, str); return result; }, isLogin(){ if(api.getPrefs({sync: true,key: 'userid'})){ return true; } return false; }, openDataBase(){ var fs = api.require('fs'); var db = api.require('db'); db.subfile({ directory:'fs://db' }, (ret, err)=> { if(ret.status){ //关上数据库 db.openDatabase({ name: 'doc', path: ret.files[0] }, (ret, err)=> { if (ret.status) { // api.toast({ // msg:'关上数据库胜利！' // }) } else { api.toast({ msg:JSON.stringify(err) }) } }); } else{ //拷贝文件 fs.copyTo({ oldPath: 'widget://doc.db', newPath: 'fs://db/' }, function(ret, err) { if (ret.status) { db.subfile({ directory:'fs://db' }, (ret, err)=> { if(ret.status){ //关上数据库 db.openDatabase({ name: 'doc', path: ret.files[0] }, (ret, err)=> { if (ret.status) { } else { api.toast({ msg:JSON.stringify(err) }) } }); } else{ api.toast({ msg:JSON.stringify(err) }) } }) } else { api.toast({ msg:JSON.stringify(err) }) } }); } }) }}export default $util;11、用户性能权限
零碎分为2级用户，管理员账号和领导账号。通过角色ID进行辨别，管理员账号有信息的增删改查性能，领导账号只有信息的查问性能。
用于登录胜利之后将用户信息进行缓存。
//登陆APP submit() { api.showProgress(); // console.log( "select id,username,password from user where username = '"+this.data.user+"' and password = '"+md5(this.data.psw)+"'"); var db = api.require('db'); db.selectSql({ name: 'doc', sql: "select id,username,password,role from user where username = '"+this.data.user+"' and password = '"+md5(this.data.psw)+"'" }, (ret, err)=> { // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { if(ret.data.length==1){ api.setPrefs({key:'username',value:ret.data[0].username}); api.setPrefs({key:'userid',value:ret.data[0].id}); api.setPrefs({key:'password',value:ret.data[0].password}); api.setPrefs({key:'role',value:ret.data[0].role}); api.sendEvent({ name: 'loginsuccess', }); api.closeWin(); } else{ api.toast({ msg:'登陆失败，请输出正确的用户名和明码' }) } } else { api.toast({ msg:JSON.stringify(err) }) } api.hideProgress(); }); }在须要验证用户权限的中央通过获取角色ID，进行逻辑判断。
if(api.getPrefs({sync: true,key: 'role'})=='99'){ //增加编辑按钮 api.setNavBarAttr({ rightButtons: [{ text: '编辑' }] }); //监听右上角按钮点击事件 api.addEventListener({ name: 'navitembtn' }, (ret, err) => { if (ret.type == 'right') { $util.openWin({ name: 'personedit', url: 'personedit.stml', title: '人员信息编辑', pageParam:{ id:this.data.id } }); } }); } else{ //增加朗诵按钮 api.setNavBarAttr({ rightButtons: [{ text: '朗诵' }] }); //监听右上角按钮点击事件 api.addEventListener({ name: 'navitembtn' }, (ret, err) => { // console.log(JSON.stringify(this.data.info)); if (ret.type == 'right') { var IFlyVoice = api.require('IFlyVoice'); IFlyVoice.initSpeechSynthesizer((ret)=>{ // console.log(JSON.stringify(ret)); }); IFlyVoice.startSynthetic({ text:this.data.info, commonPath_Android:'widget://res/android/common.jet', pronouncePath_Android:'widget://res/android/xiaoyan.jet', pronounceName:'xiaoyan', speed:40 },(ret,err)=>{ // console.log(JSON.stringify(ret)); // console.log(JSON.stringify(err)); if (ret.status) { // console.log('合成胜利'); } else { // console.log(JSON.stringify(err)); } }); } }); }12、双击退出应用程序
利用如果不做任何解决，在利用初始页面登程keyback事件，会弹出提示框提醒是否退出程序，体验感极差。针对此进行了优化，因为利用首页采纳了tablayout，所以只须要在tablayout默认选中项的索引页面中增加双击keyback事件的监听，并通过api.toast进行提醒。
在登录页面也须要增加此监听，应为用户退出登录之后，会主动跳转至登录页，如果不做解决，用户点击物理返回键就会导致用户在没有登录的状况下跳回上一页。加了此监听事件用户点击返回键不做解决，双击会提醒退出程序。
//监听返回 双击退出程序 api.setPrefs({ key: 'time_last', value: '0' }); api.addEventListener({ name : 'keyback' }, (ret, err) => { var time_last = api.getPrefs({sync: true,key: 'time_last'}); var time_now = Date.parse(new Date()); if (time_now - time_last > 2000) { api.setPrefs({key:'time_last',value:time_now}); api.toast({ msg : '再按一次退出APP', duration : 2000, location : 'bottom' }); } else { api.closeWidget({ silent : true }); } });13、利用动静权限
安卓10之后，对利用的权限要求进步，不在像老版本一样配置上就会主动获取，必须进行提醒。
根据官网给出的教程进行了动静权限的设置。
增加 mianfest.xml文件
<?xml version="1.0" encoding="UTF-8"?><manifest> <application name="targetSdkVersion" value="28"/></manifest>在零碎索引页进行动静权限获取揭示，本零碎只波及到了文件存储权限的获取，如须要获取多个权限，在List[]数组中持续增加须要的权限，而后依据增加的权限个数，做相应的几个判断即可。
let limits=[]; //获取权限 var resultList = api.hasPermission({ list: ['storage'] }); if (resultList[0].granted) { // 已受权，能够持续下一步操作 } else { limits.push(resultList[0].name); } if(limits.length>0){ api.requestPermission({ list: limits, }, (res) => { }); }
