Question

ionic怎么获得当前应用的版本号插件

Answer 1

1、准备工作，添加插件

[java] view plain copy print?在CODE上查看代码片派生到我的代码片
如果cordova 未添加请先执行以下命令
1、npm install bower -g //安装bower
2、bower install ngCordova //安装cordova

1.1、添加获取APP版本信息插件
[java] view plain copy print?在CODE上查看代码片派生到我的代码片
ionic plugin add cordova-plugin-app-version

2.2、添加APP自动更新相关插件
[java] view plain copy print?在CODE上查看代码片派生到我的代码片
ionic plugin add cordova-plugin-file
ionic plugin add cordova-plugin-file-transfer
ionic plugin add cordova-plugin-file-opener2

2、在APP一运行的时候就进行检查版本信息(在run方法添加如下代码)

.run(function($ionicPlatform, $http, $rootScope, $ionicActionSheet, $timeout, $cordovaAppVersion,
$ionicPopup, $ionicLoading, $cordovaFileTransfer, $cordovaFile, $cordovaFileOpener2) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if (window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
};
if (window.StatusBar) {
StatusBar.styleDefault();
};
//服务器上保存版本信息
$http.get('http://localhost/app/ver.json')
.then(function(data){
var serverAppVersion = data.data.verInfo;//服务器 版本
console.log("====>>服务器"+serverAppVersion);
$cordovaAppVersion.getVersionNumber().then(function(version) {
console.log("version=====本机>>>"+version+"====>>服务器"+serverAppVersion);
if (version != serverAppVersion) {
$ionicLoading.show({
template: "已经下载：0%"
});
var url = "http://192.168.1.77:8080/app/android-debug.apk";
var targetPath = "file:///mnt/sdcard/Download/android-debug.apk";
var trustHosts = true
var options = {};
$cordovaFileTransfer.download(url, targetPath, options, trustHosts).then(function (result) {
$cordovaFileOpener2.open(targetPath, 'application/vnd.android.package-archive'
).then(function () {
}, function (err) {
});
$ionicLoading.hide();
}, function (err) {
alert('下载失败');
}, function (progress) {
$timeout(function () {
var downloadProgress = (progress.loaded / progress.total) * 100;
$ionicLoading.show({
template: "已经下载：" + Math.floor(downloadProgress) + "%"
});
if (downloadProgress > 99) {
$ionicLoading.hide();
}
})
});
}
});
});

});

})

3、在服务端webapp下添加以下两个文件

1、ver.json
2、Android-debug.apk
