我目前正在使用 ActionScript 3 试验 AMFPHP，一切正常，但是当我将数据插入数据库时​​出现以下错误，但数据将插入我的数据库。

下面是PHP中的代码：

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

现在忽略安全问题我是最新的 SQL 注入，但现在这并不重要。

我的 AS3 代码如下所示：

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;

我收到此错误：

ReferenceError：错误＃1069：serverInfo找不到属性String并且没有默认值。在 test2_fla::MainTimeline/onResult()

我不明白错误的重点，这就是我无法调试代码的原因。

显然，您在响应中收到了一个未分类的字符串。对您在 onResult() 函数中传递的对象类型进行调试，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]);
    }
}
