win7下vs中实现onvif discovery(客户端、服务端)

本文介绍了如何在 Windows 7 上的 Visual Studio 中使用 gSOAP 库实现 ONVIF 设备的发现功能。通过提供服务端和客户端的代码示例，演示了如何编写 Probe、Hello 和 Bye 消息。服务端代码包括对这些消息的定义以及 main 函数的实现。客户端代码则需要生成相应代码。通过 ONVIF Device Test Tool 测试，服务端可以被成功发现。然而，要搜索特定设备，可能需要进一步修改 soap_call___dndl__Probe 函数及 printf 输出结构体的指针，同时考虑网络环境。

用gosap生成C代码框架在这里忽略。

1.服务端需要添加的代码：首先对Probe、Hello、Bye进行了定义，然后对编写main函数。
