as3錯誤屬性serverInfo找不到字符串，並且沒有默認值

Question

我目前正在用ActionScript 3試驗AMFPHP，並且一切都很好，但是當我將數據插入到數據庫時出現以下錯誤，但是數據將插入到我的數據庫。

下面的PHP代碼第一：

<?php 
public function setColor($kleur){ 
    mysql_query("INSERT INTO kleuren (kleuren) VALUES ("'.$kleuren."')"); 
    return $kleur; 
?> 

忽略安全問題，現在我是最新的SQL注入，但是這並不重要，現在。

我的AS3代碼如下所示：

import fl.controls.Button; 
import fl.events.ComponentEvent; 
import flash.display.Stage; 
import flash.display.Sprite; 
import flash.events.MouseEvent; 
import flash.net.NetConnection; 
import flash.net.Responder; 
import flash.text.TextField; 
import flash.text.TextFormat; 
import flash.text.TextFieldAutoSize;

我得到這個錯誤：

ReferenceError: Error #1069: Property serverInfo not found on String and there is no default value. at test2_fla::MainTimeline/onResult()

我沒有得到錯誤的點，這是我不能調試的原因，我的碼。

很明顯，您會在回覆中收到未分類的字符串。在你的onResult（）函數中通過什麼類型的對象進行調試，如下所示：

function onResult(responds:Object):void 
{ 
    if (responds is Array) { 
     trace('Array has been received:',responds); 
     // do something with that array 
    } else if (responds is String) { 
     trace('String has been received:',responds); 
     // do something with that string 
    } else { 
     trace('An object of unknown type has been received:',responds); 
     for (var i:String in responds) trace('['+i+']',responds[i]); 
    } 
}
