首先介绍下自己的思路:现在air都分模块化的,所以也是分模块进行更新,外加程序进行更新,
就是从远程download下载swf然后替换本地的,程序更新是先down下来,然后使用自带的updater进行更新
说实在的我的flex有时候也弄不懂,有时候改了一个地方,不知道编译器会更改哪里,更新要先测试,是不是指更改了这一个模块;
好了上代码,首先是模块更新
package com.fileOperations
{
public class FileModuleUpdate extends Sprite
{
public function FileModuleUpdate()
{
}
/**
* 需要更新的数量
* */
private var swfCount:Number = 0;
/**
* 已经更新的数量
* */
private var updatedCount:Number = 0;
private var newVersionXML:XML;
/**
* 获取新的配置文件
* */
public function getNewFileVersionConfigXMl(url:String):void{
swfCount = 0;
updatedCount = 0;
var loadUrl:URLLoader = new URLLoader();
loadUrl.load(new URLRequest(url));
loadUrl.addEventListener(Event.COMPLETE,checkIsUpdated);
}
private var url:String;//地址
private var _description:String;//升级描述
/**
* 检查这个文件是不是需要更新,由总的文件版本号确定
* */
private function checkIsUpdated(event:Event):void{
var loader:URLLoader = URLLoader(event.target);
var xml:XML = XML(loader.data);
newVersionXML = xml;
var object:XML;
for(var i:int = 0;i<xml.children().length();i++){
object = xml.children()[i] as XML;
var id:String = object.attribute("id");
if(id == "v_main"){
var version:String = (object.children()[0] as XML).@['value'];
var dic :Dictionary = IocAppFacade.getInstance().getObject("v_main") as Dictionary;
if(getIsHideVersion(dic,version)){
url = (object.children()[1] as XML).@['value'];
description = (object.children()[2] as XML).@['value'];
dispatchEvent(new FileUpdateEvent(FileUpdateEvent.FILE_HAVE_UPDATE,xml));
}else{
dispatchEvent(new FileUpdateEvent(FileUpdateEvent.NOT_FILE_HAVE_UPDATE));
}
break;
}
}
loader.close();
}
public function updateFileMoudle(xml:XML):void{
updateThisSystem(xml);
}
/**
* 判断版本号的大小
* */
private function getIsHideVersion(dic:Dictionary,version:String):Boolean{
if(dic==null||version.length==0){return false;}
var local:Number = Number((dic['version'] as String).replace(".",""));
var online:Number = Number(version.replace(".",""));
return online>local;
}
/**
* 检查这个文件是不是需要更新
* */
private function updateThisSystem(xml:XML):void{
var object:XML;
var id:String;
var version:String;
var palce:String;
for(var i:int = 2;i<xml.children().length();i++){
object = xml.children()[i] as XML;
id = object.attribute("id");
version= (object.children()[0] as XML).@['value'];
palce= (object.children()[1] as XML).@['value'];
var dic :Dictionary = IocAppFacade.getInstance().getObject(id) as Dictionary;
if(dic==null||getIsHideVersion(dic,version)){
swfCount++;
if(palce.lastIndexOf("swf")!=-1){
updateThisModule(palce);
}else{
updateThisConfig(palce);
}
}
}
}
private function updateThisConfig(path:String):void{
var loadUrl:URLLoader = new URLLoader();
loadUrl.load(new URLRequest(url+path));
loadUrl.addEventListener(Event.COMPLETE,function():void{
var xml:XML = XML(loadUrl.data);
saveXML(xml,path);
swfUpdateSuccess(null);
loadUrl.close();
});
}
/**
* 更新这个,模块
* */
private function updateThisModule(path:String):void{
var loadUrl:URLLoader = new URLLoader();
loadUrl.dataFormat = URLLoaderDataFormat.BINARY;
loadUrl.load(new URLRequest(url+path));
loadUrl.addEventListener(Event.COMPLETE,function():void{
var stream:FileStream = new FileStream();
var fileName:String = getFileName(path);
var file:File = new File(fileName);
stream.openAsync(file, FileMode.UPDATE);
stream.addEventListener(IOErrorEvent.IO_ERROR,function(e:IOErrorEvent):void{
swfUpdateSuccess(null);
stream.close(); //这个是用来放置用户磁盘保护这样就会报错,所以会监视,关闭
});
stream.addEventListener(Event.CLOSE,swfUpdateSuccess);
stream.writeBytes(loadUrl.data);
stream.close();
loadUrl.close();
});
loadUrl.addEventListener(IOErrorEvent.IO_ERROR,function(e:IOErrorEvent):void{
swfUpdateSuccess(null);
trace(e.toString()+"--------------流错误");
loadUrl.close();
});
}
private function swfUpdateSuccess(e:Event):void{
updatedCount++;
var percentage:Number = Math.floor(updatedCount*100/swfCount);
dispatchEvent(new FileUpdateEvent(FileUpdateEvent.UPDATE_PERCENTAGE,percentage));
if(updatedCount == swfCount){
dispatchEvent(new FileUpdateEvent(FileUpdateEvent.UPDATE_COMPLETE));
saveXML(newVersionXML,"更新文件XML名");
}
}
/**
* 对xml文件进行存储
* */
private function saveXML(xml:XML,name:String):void{
var xmlOperation:ConfigXmlOperation = new ConfigXmlOperation();
xmlOperation.fileName = File.applicationDirectory.resolvePath(name).nativePath;
xmlOperation.writeConfigXml(xml);
}
/**
* 获取文件的真是路径
* */
private function getFileName(path:String):String{
var fileName:String = File.applicationDirectory.resolvePath("根目录的一个文件名").nativePath;
fileName = fileName.substring(0,fileName.indexOf("根目录的一个文件名"));
return fileName += path;
}
public function get description():String{
return _description;
}
public function set description(value:String):void{
_description = value;
}
}
}
然后是air文件更新代码:
package com.copote.fileOperations
{
public class AirFileUpdate extends Sprite
{
public function AirFileUpdate()
{
}
/**
* 文件的地址
* */
private var url:String;
/**
* 文件的版本号
* */
private var newVersion:String;
public function checkMainAirIsNeedUpdate(xml:XML):void{
var object:XML;
for(var i:int = 0;i<xml.children().length();i++){
object = xml.children()[i] as XML;
var id:String = object.attribute("id");
if(id == "文件名"){
newVersion = (object.children()[0] as XML).@['value'];
var dic:Dictionary = IocAppFacade.getInstance().getObject("文件名") as Dictionary;
url = dic['palce'];
dispatchEvent(new FileUpdateEvent(FileUpdateEvent.AIR_HAVE_UPDATE,getIsHideVersion(dic,newVersion)));
break;
}
}
}
/**
* 判断版本号的大小
* */
private function getIsHideVersion(dic:Dictionary,version:String):Boolean{
var local:Number = Number((dic['version'] as String).replace(".",""));
var online:Number = Number(version.replace(".",""));
return online>local;
}
public function updateAIR():void{
var file:File = new File(fileName);
var loadUrl:URLLoader = new URLLoader();
loadUrl.dataFormat = URLLoaderDataFormat.BINARY;
loadUrl.load(new URLRequest(url));
loadUrl.addEventListener(ProgressEvent.PROGRESS,getLoadProgress);
loadUrl.addEventListener(Event.COMPLETE,function():void{
var stream:FileStream = new FileStream();
var file:File = new File(fileName);
stream.openAsync(file, FileMode.UPDATE);
stream.addEventListener(IOErrorEvent.IO_ERROR,function(e:IOErrorEvent):void{
stream.close(); //这个是用来放置用户磁盘保护这样就会报错,所以会监视,关闭
});
stream.addEventListener(Event.CLOSE,updateFile);
stream.writeBytes(loadUrl.data);
stream.close();
});
loadUrl.addEventListener(IOErrorEvent.IO_ERROR,function(e:IOErrorEvent):void{
trace(e.toString()+"--------------流错误");
loadUrl.close();
});
}
private function get fileName():String{
var fileName:String = File.applicationDirectory.resolvePath("根目录的一个文件名").nativePath;
fileName = fileName.substring(0,fileName.indexOf("根目录的一个文件名"));
return fileName+"文件名";
}
private function updateFile(event:Event):void{
var updater:Updater=new Updater ;
var airFile:File= File.applicationDirectory.resolvePath("文件名");
updater.update(airFile,newVersion);
}
private function getLoadProgress(e:ProgressEvent):void{
var percentage:Number = Math.floor(e.bytesLoaded*100/e.bytesTotal);
dispatchEvent(new FileUpdateEvent(FileUpdateEvent.UPDATE_PERCENTAGE,percentage));
}
}
}
更新中的事件
package com.copote.fileOperations.event
{
import flash.events.Event;
public class FileUpdateEvent extends Event
{
/**
* 文件升级
* */
public static const FILE_HAVE_UPDATE:String = "fileHaveUpdate";
/**
* 文件升级
* */
public static const NOT_FILE_HAVE_UPDATE:String = "notFileHaveUpdate";
/**
* 主程序升级
* */
public static const AIR_HAVE_UPDATE:String = "airFileHaveUpdate";
/**
* 以加载的百分比
* */
public static const UPDATE_PERCENTAGE:String = "updatePercentage";
/**
* 更新完成
* */
public static const UPDATE_COMPLETE:String = "updateComplete";
public var data:Object;
public function FileUpdateEvent(type:String, mydata:Object =null, bubbles:Boolean = false, cancelable:Boolean = false)
{
super(type, bubbles,cancelable);
data = mydata;
}
}
}
界面就不写了,这里自己接触了流和文件读写,学习了下,配置文件时读取的xml
像这样子:
<object id="v_main" class="flash.utils.Dictionary"> <property name="version" value="0.3.6"></property> <property name="palce" value="连接文件的目录"></property> <property name="description" value="增加了一部分功能,修改了部分bug,对一些界面做了美化"></property> </object>
本地配置文件使用spring来读取的
存在的问题是,如果要更新就要对每一个模块写配置,比较麻烦
