onvif的openssl和gsoap的环境搭建可以参考上一篇
海思[Hi3531]onvif协议实现基于gsoap和openssl

编写代码

直接附上main函数代码

int result = 0;
struct soap soap;
soap_init(&soap);
enum xsd__boolean ForceStorage;
//******************************************************************
char * ip;
char Mediaddr[256] = "";
char profile[256] = "";
struct _tds__GetCapabilities            	req;
struct _tds__GetCapabilitiesResponse    	rep;

req.Category = (enum tt__CapabilityCategory *)soap_malloc(&soap, sizeof(int));
//申请4个字节内存
req.__sizeCategory = 1;//元素序列的类型
*(req.Category) = (enum tt__CapabilityCategory)0;//0意味着要获取全部类型信息的枚举


char endpoint[255];
memset(endpoint, '\0', 255);
if (argc > 1)
{
    
	ip = argv[1];
}
else
{
    
	ip = "192.168.1.18";
}
sprintf(endpoint, "http://%s/onvif/device_service", ip);
//这里输入想要获取信息的模块的地址
soap_call___tds__GetCapabilities(&soap, endpoint, NULL, &req, &rep);
if (soap.error)
{
    
	printf("[%s][%d]--->>> soap result: %d, %s, %s\n", __func__, __LINE__,
		soap.error, *soap_faultcode(&soap),
		*soap_faultstring(&soap));
}
else
{
    
	printf("get capability success\n");
	printf("Mediaddr_XAddr====%s\n", rep.Capabilities->Media->XAddr);
	strcpy(Mediaddr, rep.Capabilities->Media->XAddr);
}
printf("\n");
return result;

Makefile文件编写

Makefile.inc文件内容：

烧录程序

编译完成后会生成如图执行文件

如果有网口你可以用nfs文件系统或者tftp传输程序，没的话就用SecureCRT串口传输
