Linux下onvif客户端获取ipc摄像头 GetServices：获取媒体地址（有的h265摄像头必须要这个接口）...

GetServices：获取媒体地址（有些h265的摄像头必须用到这个接口，得到获取能力时没获取到的另一个媒体地址）

鉴权：但是在使用这个接口之前是需要鉴权的。ONVIF协议规定，部分接口需要鉴权，部分接口不需要鉴权，在调用需要鉴权的接口时不使用鉴权，会导致接口调用失败。实现鉴权的方式之一可以调用gSOAP源码中的 soap_wsse_add_UsernameTokenDigest()函数。要安装依赖库OpenSSL

 

实现代码：

#include 
#include <string.h>
#include 

#include "soapH.h"
#include "stdsoap2.h"
#include "soapStub.h"
#include "wsseapi.h"

#include "wsdd.nsmap" //命名空间

static struct soap* ONVIF_Initsoap(struct SOAP_ENV__Header *header, const char *was_To, const char *was_Action, int timeout)
{
    struct soap *soap = NULL;    // soap环境变量
    unsigned char macaddr[6];
    char _HwId[1024];
    unsigned int Flagrand;

    soap = soap_new();
    if(soap == NULL)
    {
        printf("[%d]soap = NULL\n", __LINE__);
        return NULL;
    }

    soap_set_namespaces(soap, namespaces);   // 设置soap的namespaces，即设置命名空间

    // 设置超时（超过指定时间没有数据就退出）
    if(timeout > 0)
    {
        soap->recv_timeout = timeout;
        soap->send_timeout = timeout;
        soap->connect_timeout = timeout;
    }
    else
    {
        //Maximum waittime : 20s
        soap->recv_timeout  = 20;
        soap->send_timeout  = 20;
        soap->connect_timeout = 20;
    }

    soap_default_SOAP_ENV__Header(soap, header);

    //Create SessionID randomly,生成uuid(windows下叫guid，linux下叫uuid)，格式为urn:uuid:8-4-4-4-12，由系统随机产生

    sprintf(_HwId, "urn:uuid:%ud68a-1dd2-11b2-a105-%02X%02X%02X%02X%02X%02X", Flagrand, macaddr[0], macaddr[1], macaddr[2],macaddr[3],macaddr[4],macaddr[5]);
    header->wsa__MessageID = (char *)malloc(100);  
    memset(header->wsa__MessageID, 0, 100);
    strncpy(header->wsa__MessageID, _HwId, strlen(_HwId));    //wsa__MessageID存放的是uuid

    if(was_Action != NULL)
    {
        header->wsa__Action = (char*)malloc(1024);
        memset(header->wsa__Action, '\0', 1024);
        strncpy(header->wsa__Action, was_Action, 1024); //
    }
    if(was_To != NULL)
    {
        header->wsa__To = (char *)malloc(1024);
        memset(header->wsa__To, '\0', 1024);

    }

    return soap;
}


//释放函数
