onvif开发之设备发现功能的实现--转

忙了一个多月，onvif总算告一段落了。这几个星期忙着其他的项目，也没有好好整理一下onvif的东西。接下来得好好整理一下自己的项目思路和项目经验，同时将自己的一些心得写出来，希望对人有所帮助。

        相信大多数兄弟和我一样，onvif开发，最开始做的就是发现功能。这两天登录onvif的官网看才发现，onvif版本在八月份有更新，已经更新到V2.4了，于是下载最新的版本来进行。代码的生成可以详见我的前一篇文章。V2.4版本新增了一个wsdl文件，现在用于生成源码的文件一共有18个。为了保证全功能，最好一次性生成包含所有功能的源码。然后根据最新生成的源码来实现onvif客户端和服务端的发现功能。

1. 创建onvif_test目录。以下这些源码由最新的gsoap（2.8.16）和最新的onvif的wsdl文件（2.4）生成。（截止2013.09.16）

onvif.h

soapClientLib.c

soapServerLib.c

soapC.c

soapClient.c

soapH.h

soapServer.c

soapStub.h

2.以下文件来自gsoap_2.8.16gsoap-2.8gsoap

stdsoap2.c

stdsoap2.h

3.以下文件来自gsoap_2.8.16gsoap-2.8gsoapcustom

duration.c

4.生成的soapClientLib.c和soapServerLib.c无实际作用，可直接删除。

5.增加自定义文件：

onvif_server.c   onvif服务端实现代码

onvif_client.c   onvif客户端实现代码

onvif_server_interface.c   onvif服务端接口实现

onvif_function.c  onvif实现函数，公用

onvif_function.h  onvif实现函数，公用

onvif_server.c为服务端的实现代码，主要是定义main函数，服务端主要是监听，并处理和应答消息。

Main函数定义如下：

int main(int argc,char ** argv)
{
    printf("[%s][%d][%s][%s] start 
", __FILE__, __LINE__, __TIME__, __func__);

    int count = 0;
    struct soap ServerSoap;
    struct ip_mreq mcast;

    soap_init1(&ServerSoap, SOAP_IO_UDP | SOAP_XML_IGNORENS);
    soap_set_namespaces(&ServerSoap,  namespaces);

    printf("[%s][%d][%s][%s] ServerSoap.version = %d 
", __FILE__, __LINE__, __TIME__, __func__, ServerSoap.version);

    if(!soap_valid_socket(soap_bind(&ServerSoap, NULL, ONVIF_LISTEN_PORT, 10)))
    {
        soap_print_fault(&ServerSoap, stderr);
        exit(1);
    }

    mcast.imr_multiaddr.s_addr = inet_addr("239.255.255.250");
    mcast.imr_interface.s_addr = htonl(INADDR_ANY);

    if(setsockopt(ServerSoap.master, IPPROTO_IP, IP_ADD_MEMBERSHIP, (char*)&mcast, sizeof(mcast)) < 0)
    {
            printf("setsockopt error! error code = %d,err string = %s
",errno,strerror(errno));
        return 0;
    }

    for(;;)
    {
        if(soap_serve(&ServerSoap))
        {
            soap_print_fault(&ServerSoap, stderr);
        }

        soap_destroy(&ServerSoap);
        soap_end(&ServerSoap);

        //客户端的IP地址
        printf("RECEIVE count %d, connection from IP = %lu.%lu.%lu.%lu socket = %d 
", count, ((ServerSoap.ip)>>24)&0xFF, ((ServerSoap.ip)>>16)&0xFF, ((ServerSoap.ip)>>8)&0xFF,(ServerSoap.ip)&0xFF, (ServerSoap.socket));
        count++;
    }

    //分离运行时的环境
    soap_done(&ServerSoap);

    return 0;
}

onvif_server_interface.c   此文件用来定义所有服务端需要填充的接口。这里我们填充__wsdd__Probe接口即可，其他赞不支持的接口可以用宏统一处理。

__wsdd__Probe的填充如下：

SOAP_FMAC5 int SOAP_FMAC6  __wsdd__Probe(struct soap* soap, struct wsdd__ProbeType *wsdd__Probe)
{

    #define MACH_ADDR_LENGTH 6
    #define INFO_LENGTH 512
    #define LARGE_INFO_LENGTH 1024
    #define SMALL_INFO_LENGTH 512

    printf("[%d] __wsdd__Probe start !
", __LINE__);

    unsigned char macaddr[6] = {0};
    char _IPAddr[INFO_LENGTH] = {0};
    char _HwId[1024] = {0};

    wsdd__ProbeMatchesType ProbeMatches;
    ProbeMatches.ProbeMatch = (struct wsdd__ProbeMatchType *)soap_malloc(soap, sizeof(struct wsdd__ProbeMatchType));
    ProbeMatches.ProbeMatch->XAddrs = (char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);
    ProbeMatches.ProbeMatch->Types = (char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);
    ProbeMatches.ProbeMatch->Scopes = (struct wsdd__ScopesType*)soap_malloc(soap,sizeof(struct wsdd__ScopesType));

    ProbeMatches.ProbeMatch->wsa__EndpointReference.ReferenceParameters = (struct wsa__ReferenceParametersType*)soap_malloc(soap,sizeof(struct wsa__ReferenceParametersType));
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ServiceName = (struct wsa__ServiceNameType*)soap_malloc(soap,sizeof(struct wsa__ServiceNameType));
    ProbeMatches.ProbeMatch->wsa__EndpointReference.PortType = (char **)soap_malloc(soap, sizeof(char *) * SMALL_INFO_LENGTH);
    ProbeMatches.ProbeMatch->wsa__EndpointReference.__any = (char **)soap_malloc(soap, sizeof(char*) * SMALL_INFO_LENGTH);
    ProbeMatches.ProbeMatch->wsa__EndpointReference.__anyAttribute = (char *)soap_malloc(soap, sizeof(char) * SMALL_INFO_LENGTH);
    ProbeMatches.ProbeMatch->wsa__EndpointReference.Address = (char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);

    netGetMac("eth4", macaddr); //eth0  根据实际情况填充
    macaddr[0]=0x01;macaddr[1]=0x01;macaddr[2]=0x01;macaddr[3]=0x01;macaddr[4]=0x01;macaddr[5]=0x01;
    sprintf(_HwId,"urn:uuid:2419d68a-2dd2-21b2-a205-%02X%02X%02X%02X%02X%02X",macaddr[0], macaddr[1], macaddr[2], macaddr[3], macaddr[4], macaddr[5]);


    unsigned int localIp = 0;
    netGetIp("eth4", &localIp); //eth0 根据实际情况填充
    sprintf(_IPAddr, "http://%s/onvif/device_service", inet_ntoa(*((struct in_addr *)&localIp)));
    printf("[%d] _IPAddr ==== %s
", __LINE__, _IPAddr);

    ProbeMatches.__sizeProbeMatch = 1;
    ProbeMatches.ProbeMatch->Scopes->__item =(char *)soap_malloc(soap, 1024);
    memset(ProbeMatches.ProbeMatch->Scopes->__item,0,sizeof(ProbeMatches.ProbeMatch->Scopes->__item));

    //Scopes MUST BE
    strcat(ProbeMatches.ProbeMatch->Scopes->__item, "onvif://www.onvif.org/type/NetworkVideoTransmitter");

    ProbeMatches.ProbeMatch->Scopes->MatchBy = NULL;
    strcpy(ProbeMatches.ProbeMatch->XAddrs, _IPAddr);
    strcpy(ProbeMatches.ProbeMatch->Types, wsdd__Probe->Types);
    printf("wsdd__Probe->Types=%s
",wsdd__Probe->Types);
    ProbeMatches.ProbeMatch->MetadataVersion = 1;

    //ws-discovery规定 为可选项
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ReferenceProperties->__size = 0;
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ReferenceProperties->__any = NULL;
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ReferenceParameters->__size = 0;
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ReferenceParameters->__any = NULL;

    ProbeMatches.ProbeMatch->wsa__EndpointReference.PortType[0] = (char *)soap_malloc(soap, sizeof(char) * SMALL_INFO_LENGTH);
    //ws-discovery规定 为可选项
    strcpy(ProbeMatches.ProbeMatch->wsa__EndpointReference.PortType[0], "ttl");
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ServiceName->__item = NULL;
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ServiceName->PortName = NULL;
    ProbeMatches.ProbeMatch->wsa__EndpointReference.ServiceName->__anyAttribute = NULL;
    ProbeMatches.ProbeMatch->wsa__EndpointReference.__any[0] = (char *)soap_malloc(soap, sizeof(char) * SMALL_INFO_LENGTH);
    strcpy(ProbeMatches.ProbeMatch->wsa__EndpointReference.__any[0], "Any");
    strcpy(ProbeMatches.ProbeMatch->wsa__EndpointReference.__anyAttribute, "Attribute");
    ProbeMatches.ProbeMatch->wsa__EndpointReference.__size = 0;
    strcpy(ProbeMatches.ProbeMatch->wsa__EndpointReference.Address, _HwId);

    soap->header->wsa__To = "http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous";
    soap->header->wsa__Action = "http://schemas.xmlsoap.org/ws/2005/04/discovery/ProbeMatches";

        if (SOAP_OK == soap_send___wsdd__ProbeMatches(soap, "http://", NULL, &ProbeMatches))
        {
        printf("send ProbeMatches success !
");
        return SOAP_OK;
    }

    printf("[%d] soap error: %d, %s, %s
", __LINE__, soap->error, *soap_faultcode(soap), *soap_faultstring(soap));

    return soap->error;;

}

onvif_client.c   onvif客户端实现代码，主要是定义客户端的main函数：

Main定义如下：

int main()
{
    printf("[%s][%d][%s][%s] start 
", __FILE__, __LINE__, __TIME__, __func__);

    int result = 0;
    wsdd__ProbeType req;
    struct __wsdd__ProbeMatches resp;
    wsdd__ScopesType sScope;
    struct SOAP_ENV__Header header;

    struct soap *soap;
    soap = soap_new();
    if(NULL == soap )
    {
        printf("sopa new error
");
        return -1;
    }

    soap->recv_timeout = 10;
    soap_set_namespaces(soap, namespaces);
    soap_default_SOAP_ENV__Header(soap, &header);

    uuid_t uuid;
    char guid_string[100];
    uuid_generate(uuid);
    uuid_unparse(uuid, guid_string);

    header.wsa__MessageID = guid_string;
    header.wsa__To = "urn:schemas-xmlsoap-org:ws:2005:04:discovery";
    header.wsa__Action = "http://schemas.xmlsoap.org/ws/2005/04/discovery/Probe";
    soap->header = &header;

    soap_default_wsdd__ScopesType(soap, &sScope);
    sScope.__item = "";
    soap_default_wsdd__ProbeType(soap, &req);
    req.Scopes = &sScope;
    req.Types = ""; //"dn:NetworkVideoTransmitter";

    int i = 0;
       result = soap_send___wsdd__Probe(soap, MULTICAST_ADDRESS, NULL, &req);
       while(result == SOAP_OK)
       {
        result = soap_recv___wsdd__ProbeMatches(soap, &resp);
        if(result == SOAP_OK)
        {
            if(soap->error)
            {
                printf("soap error 1: %d, %s, %s
", soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
                result = soap->error;
            }
            else
            {
                printf("guog *********************************************
");
                if(soap->header->wsa__MessageID)
                {
                    printf("MessageID   : %s
", soap->header->wsa__MessageID);
                }
                if(soap->header->wsa__RelatesTo && soap->header->wsa__RelatesTo->__item)
                {
                    printf("RelatesTo   : %s
", soap->header->wsa__RelatesTo->__item);
                }
                if(soap->header->wsa__To)
                {
                    printf("To          : %s
", soap->header->wsa__To);
                }
                if(soap->header->wsa__Action)
                {
                    printf("Action      : %s
", soap->header->wsa__Action);
                }

                for(i = 0; i < resp.wsdd__ProbeMatches->__sizeProbeMatch; i++)
                {
                    printf("__sizeProbeMatch        : %d
", resp.wsdd__ProbeMatches->__sizeProbeMatch);
                    printf("wsa__EndpointReference       : %p
", resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference);
                    printf("Target EP Address       : %s
", resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.Address);
                    printf("Target Type             : %s
", resp.wsdd__ProbeMatches->ProbeMatch->Types);
                    printf("Target Service Address  : %s
", resp.wsdd__ProbeMatches->ProbeMatch->XAddrs);
                    printf("Target Metadata Version : %d
", resp.wsdd__ProbeMatches->ProbeMatch->MetadataVersion);
                    if(resp.wsdd__ProbeMatches->ProbeMatch->Scopes)
                    {
                        printf("Target Scopes Address   : %s
", resp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item);
                    }
                }
            }
        }
        else if (soap->error)
        {
            printf("[%d] soap error 2: %d, %s, %s
", __LINE__, soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
            result = soap->error;
        }
       }

    soap_destroy(soap);
    soap_end(soap);
    soap_free(soap);

    printf("[%d] guog discover over !
", __LINE__);

    return result;
}

6.将wsdd.nsmap改为nsmap.h，并删除其余的*.nsmap(都一样)

7.编写makefile文件。注意在makefile中打开开关DEBUG，以便跟踪日志。

8.tcpdump为gcc环境的抓包工具，调试的时候用。

make编译通过，运行，客户端发现功能ok；

    但是服务端的发现功能却不行；别急，这是由于SOAP的版本问题；soap的版本是根据命名空间来自动确定的；在soap结构体的version字段表示soap版本；

以下命名空间表示SOAP1.1版本：

{"SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/", "http://www.w3.org/*/soap-envelope", NULL},

{"SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/", "http://www.w3.org/*/soap-encoding", NULL}, //1.1

以下命名空间表示SOAP1.2版本：

{"SOAP-ENV", "http://www.w3.org/2003/05/soap-envelope", "http://schemas.xmlsoap.org/soap/envelope/", NULL},

{"SOAP-ENC", "http://www.w3.org/2003/05/soap-encoding", "http://schemas.xmlsoap.org/soap/encoding/", NULL},  //1.2

    注意确定自己当前的命名空间。我们用SOAP1.2版本才能被测试工具发现(ONVIF Device Test Tool version 13.06)。

不清楚可以查看soap_set_namespaces接口和soap_set_local_namespaces接口；

于是将nsmap.h中的命名空间前两行改为：

{"SOAP-ENV", "http://www.w3.org/2003/05/soap-envelope", "http://schemas.xmlsoap.org/soap/envelope/", NULL},

{"SOAP-ENC", "http://www.w3.org/2003/05/soap-encoding", "http://schemas.xmlsoap.org/soap/encoding/", NULL},  //1.2

再编译运行，发现功能ok。
