Flex使用AMFPHP下载文件

有人知道是否可以使用AMFPHP下载文件吗？我发现了一些使用php直接下载的示例。如果是，举例说明？我有一个使用AMFPHP上传文件的例程，但我没有在网上找到使用AMFPHP下载的示例

提前谢谢。

请用ByteArray试试。差不多 按数组返回新的Amfphp\u核心\u Amf\u类型（$data）

我找到了这篇文章：。基于此，我制作了自己的版本，因为我的服务是通过service-config.xml定义的，定义方式见amfphp文档第节

服务器端：

如果您已经知道如何配置网关以访问服务类和值对象类，那么以下是两个类：

ValueObject类：

<?php
class FileVO {

    public $filename;
    public $filedata;

    // explicit actionscript class
    var $_explicitType = "remoting.vo.FileVO";
}
?>

正在上载文件的组件：

对我来说很有效！至少在我的开发服务器上。注意这里的安全漏洞。你需要提供某种形式的保护，以防止任何滥用

package remoting.vo
{
import flash.utils.ByteArray;

  [RemoteClass(alias="FileVO")]
  public class FileVO{
    public var filename:String;
    public var filedata:ByteArray;

    public function FileVO(){
    }

  }
}
