这次继续讲上传,只不过服务器端用ColdFusion. 前台界面的FLEX程序跟上次一样,只不过把serverSideScript:String = "http://路径/uploadFile.php"换成了serverSideScript:String = "http://路径/uploadFile.cfm";
详细的FLEX代码:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init();" backgroundGradientColors="[#ffffff, #c0c0c0]">
<mx:Script>
<![CDATA[
private var urlRequest:URLRequest;
private var fileReferenceList:FileReferenceList;
//如果你是在本机上调试那么路径为:http://localhost:8500/文件夹/uploadFile.cfm;
private var serverSideScript:String = "http://路径/uploadFile.cfm";
private function init():void {
urlRequest = new URLRequest(serverSideScript);
fileReferenceList = new FileReferenceList();
fileReferenceList.addEventListener(Event.SELECT, fileSelectedHandler);
}
private function uploadFile():void {
fileReferenceList.browse();
}
private function fileSelectedHandler(event:Event):void {
var fileReference:FileReference;
var fileReferenceList:FileReferenceList = FileReferenceList(event.target);
var fileList:Array = fileReferenceList.fileList;
fileReference = FileReference(fileList[0]);
fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
fileReference.upload(urlRequest);
statusText.text = "上传中...";
}
private function uploadCompleteHandler(event:Event):void {
statusText.text = "上传成功的文件: " + event.target.name;
}
]]>
</mx:Script>
<mx:Label text="用FLEX上传文件到PHP服务器" fontSize="14" fontWeight="bold"/>
<mx:Label text="选择要上传的文件" id="statusText" fontSize="12"/>
<mx:Button click="uploadFile();" label="上传" fontSize="12"/>
</mx:Application>
现在就是服务器端的代码了,其实很简单,比PHP简单多了.注意:你需要先在C盘建立一个"uploadFile"文件夹,具体参数可以在代码里修改.
<cfprocessingdirective suppresswhitespace="true">
<cftry>
<cffile action="upload" fileField="filedata" destination="c:\uploadFile" nameconflict="overwrite">
<cfcatch>
</cfcatch>
</cftry>
</cfprocessingdirective>
