注：uploadURL.url = "http://localhost:80/ShowProduct-debug/uploadFile.php";路径一定要写对，否则回报Error #2044: 未处理的 IOErrorEvent:。 text=Error #2038: 文件 I/O 错误。
2. php代码

// Flash 传递的文件表单 name 属性为 Filedata   
$fileName = $_FILES["Filedata"]["name"]; 
$file = $_FILES["Filedata"]["tmp_name"];   
$path = "uploadFiles/";
if(!is_dir("./uploadFiles")){
  @mkdir("./uploadFiles");
}  
if (move_uploaded_file($file, $path . $fileName)){   
  echo Success;   
}else{   
  echo Fail;   
} 
?>

注：php文件一定要放到Apache运行的目录里，例如：把php文件放到C:\xampp\htdocs\ShowProduct-debug目录下
