Ionic 架構介紹

  Ionic是一個基於Angularjs、可以使用HTML5構建混合行動裝置 App的使用者介面架構,它自稱為是“本地與HTML5的結合”。該架構提供了很多基本的移動使用者介面範例,例如像列表(lists)、標籤頁欄(tab bars)和觸發開關(toggle switches)這樣的簡單條目。它還提供了更加複雜的可視化布局樣本,例如在下面顯示內容的滑出式菜單。
Ionic 自動升級APP

一、準備工作

  1.Cordova外掛程式:

    cordova plugin add https://github.com/whiteoctober/cordova-plugin-app-version.git  // 擷取APP版本
    cordova plugin add org.apache.cordova.file // 檔案系統
    cordova plugin add org.apache.cordova.file-transfer //檔案傳輸系統
    cordova plugin add https://github.com/pwlin/cordova-plugin-file-opener2 //檔案開啟系統

  2.AngularJS Cordova外掛程式

    ngCordova

二、相關代碼,app.js
複製代碼

.run([‘$ionicPlatform‘, ‘$rootScope‘,‘$ionicActionSheet‘, ‘$timeout‘,‘$cordovaAppVersion‘, ‘$ionicPopup‘, ‘$ionicLoading‘,‘$cordovaFileTransfer‘, ‘$cordovaFile‘, ‘$cordovaFileOpener2‘, function ($ionicPlatform, $rootScope,$ionicActionSheet, $timeout,  $cordovaAppVersion, $ionicPopup, $ionicLoading, $cordovaFileTransfer, $cordovaFile, $cordovaFileOpener2) {
        $ionicPlatform.ready(function ($rootScope) {
            // 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) {
                // org.apache.cordova.statusbar required
                StatusBar.styleDefault();
            }

            //檢測更新
            checkUpdate();

            document.addEventListener("menubutton", onHardwareMenuKeyDown, false);
        });


        // 菜單鍵
        function onHardwareMenuKeyDown() {
            $ionicActionSheet.show({
                titleText: ‘檢查更新‘,
                buttons: [
                    { text: ‘關於‘ }
                ],
                destructiveText: ‘檢查更新‘,
                cancelText: ‘取消‘,
                cancel: function () {
                    // add cancel code..
                },
                destructiveButtonClicked: function () {
                    //檢查更新
                    checkUpdate();
                },
                buttonClicked: function (index) {

                }
            });
            $timeout(function () {
                hideSheet();
            }, 2000);
        };

        // 檢查更新
        function checkUpdate() {
            var serverAppVersion = "1.0.0"; //從服務端擷取最新版本
            //擷取版本
            $cordovaAppVersion.getAppVersion().then(function (version) {
                //如果本地與服務端的APP版本不符合
                if (version != serverAppVersion) {
                    showUpdateConfirm();
                }
            });
        }

        // 顯示是否更新對話方塊
        function showUpdateConfirm() {
            var confirmPopup = $ionicPopup.confirm({
                title: ‘版本升級‘,
                template: ‘1.xxxx;</br>2.xxxxxx;</br>3.xxxxxx;</br>4.xxxxxx‘, //從服務端擷取更新的內容
                cancelText: ‘取消‘,
                okText: ‘升級‘
            });
            confirmPopup.then(function (res) {
                if (res) {
                    $ionicLoading.show({
                        template: "已經下載:0%"
                    });
                    var url = "http://192.168.1.50/1.apk"; //可以從服務端擷取更新APP的路徑
                    var targetPath = "file:///storage/sdcard0/Download/1.apk"; //APP下載存放的路徑,可以使用cordova file外掛程式進行相關配置
                    var trustHosts = true
                    var options = {};
                    $cordovaFileTransfer.download(url, targetPath, options, trustHosts).then(function (result) {
                        // 開啟下載下來的APP
                        $cordovaFileOpener2.open(targetPath, ‘application/vnd.android.package-archive‘
                        ).then(function () {
                                // 成功
                            }, function (err) {
                                // 錯誤
                            });
                        $ionicLoading.hide();
                    }, function (err) {
                        alert(‘下載失敗‘);
                    }, function (progress) {
                        //進度,這裡使用文字顯示下載百分比
                        $timeout(function () {
                            var downloadProgress = (progress.loaded / progress.total) * 100;
                            $ionicLoading.show({
                                template: "已經下載:" + Math.floor(downloadProgress) + "%"
                            });
                            if (downloadProgress > 99) {
                                $ionicLoading.hide();
                            }
                        })
                    });
                } else {
                    // 取消更新
                }
            });
        }
    }])

  上面是一個簡單實現方式,一些資料都在這裡寫死了,你可以將一些資料從服務端擷取,比如最新版本號碼,最新版的下載路徑,這裡提供一個思路。
