Zend_Amf Channel.Connect.Failed错误NetConnection.Call.BadVersion

Question

我目前正在使用PHP后端构建Flex应用程序。 flex应用程序应该使用Zend_AMF与后端通信。

我已将Zend_AMF端点实现为控制器，因此可以通过http://localhost/myapp/amf访问它。

我正在尝试使用名为ZamfBrowser的服务浏览器测试服务。

连接时，我收到此错误：

我已经尝试使用Google搜索解决方案，但似乎无法找到导致该错误的任何原因。我已经检查了启用了display_errors的php代码，并且没有错误。

如果我在浏览器中访问我的端点，则会收到保存应用程序/ amf文件的提示。打开它显示了Zend Amf Endpoint。

我很遗憾还有什么可能导致错误。

任何想法都赞赏。

编辑：一些PHP代码。我只是在控制器中实现Zend_AMF

class AmfController extends BaseController{

   public function __construct(){
      $server = new Zend_Amf_Server();
      $server->setProduction(false);

      $server->setClass( 'ZendAmfServiceBrowser' );
      ZendAmfServiceBrowser::setAmfServer($server);
      echo($server->handle());
   }

}

编辑：查尔斯。我尝试使用Charles打开windows代理，但它似乎没有从ZamfBrowser捕获任何内容。

如果我从rowser访问端点，系统会提示我保存文件（amf消息）。以下是查尔斯的输出：

Answer 1

对于Zend_AMF用户，NetConnection.Call.BadVersion几乎总是意味着您没有发回AMF。有时这是因为你在输出AMF之前有一个错误的echo，有时候是因为你的PHP代码中出现错误并且它正在吐出回溯，或者有时它根本没有发回任何东西。在这些情况下，我将在Windows上使用Packetyzer之类的数据包嗅探器或在Mac OS X上使用Cocoa Packet Analyzer来查看正在发回的内容。您还可以使用PHP输出缓冲区来收集所有输出并将其保存到文件中进行检查，而不是使用数据包嗅探器。

Answer 2

没有看到任何代码，我不确定，但我想知道你的网络连接的对象编码？

    import flash.net.NetConnection;
    import flash.net.ObjectEncoding;

    // Set AMF version for AMFPHP
    var netConnection:NetConnection;
    netConnection.objectEncoding = ObjectEncoding.AMF0; // instead of AMF3

Answer 3

我对ZendAMF一无所知，但在BlazeDS中，当您尝试混合'{'BadVersion和http时，您会收到https错误。
