我正在使用网络服务。我使用 eclipse 编写了一个轴 1.4 的客户端。我可以通过 ssl vpn 访问网络服务。我的轴客户端代码工作正常。但是，代码必须在 android 设备上运行。我不能在 android 上使用轴代码，因为 android 不支持 java rmi。我正在尝试通过使用 apache httpclient 库制作 httppost 来使用服务。为了查看轴请求值，我使用了 tcpmon。它帮助我轻松编写 httppost 代码。问题是，当我不使用 tcpmon 直接运行代码时，它会给我以下错误：
Exception in thread "main" java.net.SocketException: Invalid argument: setsockopt

如果我通过 tcpmon 发送请求，它可以工作。我得到了回应。我在下面给你 tcpmon 输出：

通常我希望 tcpmon 行为必须与我的本地行为相同，但 tcpmon 会改变结果。可能是什么原因？
