HTTPService AsyncToken和AsyncResponder示例

Question

我在哪裏可以找到Flex應用程序的示例，該應用程序實現由AsyncToken和AsyncResponder異步調用的HTTPService？ 在此先感謝

HTTPService在發送一個字符串像這樣具有一定頻率：

行號列＃號＃行號列＃號＃行號列＃號＃....

Answer 1

我不知道你真正尋找之後，但here或here例如，有辦法使用AsyncToken和AsyncResponder

編輯：

1. 您dataList必須Bindable
2. 不要設置dataList在每次循環迭代
3. 你要叫你在某個時刻發揮作用getResults當你的結果準備就緒
4. event in result function is a Event but also a ResultEvent whe再有一個包含數據

這可能看起來這（另）一個result場：

[Bindable] 
public var dataList:ArrayCollection; 

public function getResults(source:String) : ArrayCollection { 
    var ac:ArrayCollection = new ArrayCollection(); 
    var data:Array = source.split('#'); 
    for (var i:int = 0; i < data.length; i += 3) { 
    ac.addItem({row: data[i], column: data[i+1], value: data[i+2]}); 
    } 
    return ac; 
} 

private function result(event:ResultEvent) : void { 
dataList = getResults(String(event.result)); 
} 

EDIT2：

這是一個使用簡單的PHP文件的工作示例獲取在本地Web服務器上運行的數據。

Answer 2

private function onCreationComplete():void 
{ 
    var service:HTTPService = new HTTPService(); 
    service.url = "http://www.google.com"; 
    service.resultFormat = "text"; 
    var token:AsyncToken = service.send(); 
    token.addResponder(new mx.rpc.Responder(result, fault)); 
} 

private function result(event:Event):void 
{ 
    trace(1, event); 
} 

private function fault(event:Event):void 
{ 
    trace(2, event); 
} 

here實測值。
