3、运行结果

Build并运行上述程序，从Memo1里可以看到整个工作过程，可以看出，搜索设备、取控制页URL、增加端口映射项、查看映射项参数、删除映射项等关键步骤均符合我们预期的设想。因此，完全可以在您的应用中把本程序的有关内容集成进去。

--------------------------------------------------------------------------

（1）、以下是“搜索设备”的工作过程信息：

--------------------------------------------------------------------------

发出了如下命令：
M-SEARCH * HTTP/1.1
HOST: 239.255.255.250:1900
MAN: "ssdp:discover"
MX: 3
ST: upnp:rootdevice

从192.168.0.1:1900收到289个字节的数据！
收到的信息如下：
HTTP/1.1 200 OK
Cache-Control: max-age=1800

--------------------------------------------------------------------------

（2）、以下是“获取控制页URL”的工作过程信息：

--------------------------------------------------------------------------

向192.168.0.1:1780设备发起连接...

与192.168.0.1:1780设备成功连接

向192.168.0.1:1780提交如下查询请求：
GET /InternetGatewayDevice.xml HTTP/1.1
Host: 192.168.0.1:1780

从192.168.0.1:1780收到如下应答数据：
HTTP/1.1 200 OK
