Linux下onvif客户端获取ipc摄像头 GetProfiles：获取h265媒体信息文件

GetProfiles：获取媒体信息文件

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 <stdlib.h>
#include <string.h>
#include <assert.h>

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

#include "wsdd.nsmap" //命名空间

    char _HwId[];
    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 > )
    {
        soap->recv_timeout = timeout;
        soap->send_timeout = timeout;

    }

//释放函数
