php - 使用 Flex 移动设备登录系统

Question

我遵循了一个关于如何在 Flex 中制作登录系统的示例。此示例不是为 Flex 移动项目制作的，而是为在浏览器中运行的桌面制作的。据我了解，我可以使用相同的代码但具有不同的组件。我不断收到错误。我的代码在下面。

连接和查询数据库的PHP代码，并用xml返回结果

<?php

echo "<?xml version="\"1.0\" ?>\n";

$con = mysql_connect("HOST","USER","PASS");
if (!$con)
{
  die('Could not connect: ' . mysql_error());
}

mysql_select_db("DatabaseName here"); 

//Variables that I wil retrieve from the flex application

$user = $_POST['user']; 
$pass = $_POST['pass'];


//mySQL query 
$result = mysql_query("SELECT * FROM `brukere` WHERE 1");

//not logged in so it's false
$loged = false; 

//Comparing the text i retrieved from the flex app and the rows in my database. 

while($row = mysql_fetch_assoc($result))
{
   if(strtolower($user) == strtolower($row['brukernavn']) &&
   strtolower($pass) == strtolower($row['passord']))   
   {
         $loged = true: 
       }
} 

//so if loged is true, pass true in xml to my flex application. 
if($loged == true) 
echo "<status>true</status>"; 
else
echo "<status>false</status>"; 
?>

Flex 代码中的我的 HTTPService

    <fx:Declarations>

    <mx:HTTPService id="loginService" result="onResult(event)"  method="POST" url="URL TO THE PHP SCRIPT">

        <mx:request xmlns="">

            <user>{username.text}</user>

            <pass>{pass.text}</pass>

        </mx:request>

    </mx:HTTPService>
        </fx:Declarations>

然后是我的 ActionScript

<fx:Script>
    <![CDATA[
        import mx.rpc.events.ResultEvent;
        import mx.controls.Alert; 

        private function login():void 
        {
            loginService.send();    
        }

        private function onResult(e:ResultEvent):void
        {

            if(e.result.status == true) {

                Alert.show("Succesful"); 

            }

            else {

                Alert.show("Wrong"); 
            }
        }
    ]]>
</fx:Script>

最后是图形用户界面:

<s:VGroup includeIn="notLoggedIn" x="286" y="164" width="45%" height="200">
    <s:HGroup includeIn="notLoggedIn" width="100%" height="38" verticalAlign="middle">
        <s:Label width="30%" height="31" text="Brukernavn: " verticalAlign="middle"/>
        <s:TextInput id="username" width="70%"/>
    </s:HGroup>
    <s:Spacer width="459" height="10"/>
    <s:HGroup includeIn="notLoggedIn" width="100%" height="40" verticalAlign="middle">
        <s:Label width="30%" height="34" text="Passord:" verticalAlign="middle"/>
        <s:TextInput id="pass" width="70%"/>
    </s:HGroup>
    <s:Spacer width="458" height="10"/>
    <s:HGroup width="462" height="65">
        <s:Spacer width="70%" height="64"/>
        <s:Button width="30%" label="Logg inn" click="login()"/>
    </s:HGroup>
</s:VGroup>

这是我调试应用程序时的所有输出:

我的第一个想法是我不能使用 <mx:HTTPService>以及我的移动 Flex 应用程序中的其他基于 mx 的服务。有人知道我应该寻找什么吗？

很抱歉这篇文章很长，但至少它足够非正式:)

提前致谢
