HBuilderX开发app实现自动更新版本

  需求说明：使用MUI+Vue等技术并且通过HBuilderX打包开发移动app，在有版本更新时需要自动提示用户有新版本，并且可以点击下载自动安装。

思路说明：

1. 应用打开时（使用Vue的生命周期mounted），获取自己的版本信息appinfo；
   
   (本身app的信息一般存放在mainfest.json中，直接获取即可)

mui.plusReady(function(){
    mui.getJSON("manifest.json", null, function(manifest){
        var version = data.version
		var vercode_local = version.code;
		var vername_local = version.name;
		console.log("版本名称："+vername_local+"，版本code："+vercode_local);
    });
});

1. 获取remote服务器上移动应用最新的版本信息（一般是存放一个json的数据信息）

mui.getJSON(【服务器的url + appInfo.version_json】, null, function(data) {
	var verCode = data.verCode;
	var verName = data.verName;
	//服务器版本
	//console.log("服务器版本名称："+verName +"，服务器版本code:"+verCode);
});

1. 判断两个版本号是否相等，不相等则需要更新

if(vercode_local == verCode) {
		mui.toast("当前已经是最新版本！");
	} else {
		var btnArray = ['是', '否'];
		mui.confirm('当前版本是：' + vername_local + ',  最新版本是：' + verName + ',  是否立即更新？', '发现最新版本', btnArray, function(z) {
			if(z.index == 0) {
				console.log('确定');
				installApk(BASEINFO.maxsvc + appInfo.version_apk);
			} else {
				console.log('不确定');
				return;
			}
		});
	}

1.在vue的mounted生命周期进行更新校验

mounted() {
	mui.plusReady(function() {
		//console.log("检查更新！！！！");
		mui.init({statusBarBackground: '#EEEEEE'});
		plus.screen.lockOrientation("landscape-primary");
		if(mui.os.android) {
			mui.getJSON("../../manifest.json", null, function(data) {
				var version = data.version
				var vercode_local = version.code;
				var vername_local = version.name;
				//当前版本
				//console.log("版本名称："+vername_local+"，版本code："+vercode_local);
				mui.getJSON(BASEINFO.maxsvc + appInfo.version_json, null, function(data) {
					var verCode = data.verCode;
					//服务器版本
					//console.log("服务器版本code:"+verCode);
					var verName = data.verName;
					if(vercode_local == verCode) {
						mui.toast("当前已经是最新版本！");
					} else {
						var btnArray = ['是', '否'];
						mui.confirm('当前版本是：' + vername_local + ',  最新版本是：' + verName + ',  是否立即更新？', '发现最新版本', btnArray, function(z) {
							if(z.index == 0) {
								console.log('确定');
								installApk(BASEINFO.maxsvc + appInfo.version_apk);
							} else {
								console.log('不确定');
								return;
							}
						});
					}
				});
			});
		}
	});
}

2.其中需要用到application.js中声明的函数

3.application.js中的函数

var BASEINFO={
    //接口url
	maxsvc:"http://*.*.*.*:port/appUpdate",
	maxbiz:"http://*.*.*.*:port/maxbiz",
	download:"http://*.*.*.*:port/whatsup/releaseapk.jsp"
}

function getWinWH() {
	var temp = {};
	var winWidth = "0";
	var winHeight = "0";
	if(window.innerWidth) {
		winWidth = window.innerWidth;
	} else if((document.body) && (document.body.clientWidth)) {
		winWidth = document.body.clientWidth;
	}
	if(window.innerHeight) {
		winHeight = window.innerHeight;
	} else if((document.body) && (document.body.clientHeight)) {
		winHeight = document.body.clientHeight;
	}
	if(document.documentElement && document.documentElement.clientHeight && document.documentElement.clientWidth) {
		winHeight = document.documentElement.clientHeight;
		winWidth = document.documentElement.clientWidth;
	}
	temp.winWidth = winWidth;
	temp.winHeight = winHeight;

	return temp;
}

4.服务器端添加配置信息

1.主要添加json（新版本信息），apk（新版本安装包），desc（描述文件）
