我真的不知道出了什么问题。
我将 JSON 从 AS3 发送到 PHP：
var sendToPHPJson:String = com.adobe.serialization.json.JSON.encode(sqlResult);
myRequest = new URLRequest("http://xxx.pl/FlashFiles/Winebook/uploadToServer.php");
myLoader = new URLLoader;
myVariables = new URLVariables;
myVariables.firstProperty = sendToPHPJson;
myLoader.addEventListener(flash.events.Event.COMPLETE,onUploadingComplete);
myLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
myRequest.method = URLRequestMethod.POST;
myRequest.data = myVariables;
myLoader.load(myRequest);
我的 PHP 正在接收：
<?php
include "XXX.php";
$json=$_POST['firstProperty'];
$data = json_decode($json);
$answe=$data[0]->wineName;
echo "answer='".$answe."'";
?>
我收到答案=''。但是当我将 sendToPHPJson 硬编码为 PHP 时，答案具有很好的价值。
有什么问题？要改变什么？
*编辑：我做了一些搜索和重建代码：
AS3：
var url:String = "http://adres/uploadToServer.php";
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;
var requestVars:URLVariables = new URLVariables();
requestVars.myObject = sendToPHPJson;
request.data = requestVars;
var loader:URLLoader = new URLLoader();
loader.addEventListener(flash.events.Event.COMPLETE,onUploadingComplete);
loader.load(request);
PHP：
<?php
include "XXX.php";
ob_start();
var_dump($_POST['myObject']);
print_r($_POST);
$content = ob_get_contents();
ob_end_clean();
$wynik = json_decode($content);
echo $wynik;
?>
而且我仍然没有得到任何数据：
private function onUploadingComplete(e:flash.events.Event):void
{
trace("upload complete");
trace(e.target.data);
txtField.text = String(e.target.data);
this.touchable = true;
}
