gSoap实现ONVIF的设备发现(windows下)

一、要准备的文件：

1.ONVIF相关的WSDL文件，对于设备发现，只需要用到RemoteDiscovery.wsdl一个即可，

2.gSoap的压缩包，找到/gsoap/bin/win32文件夹中的soapcpp2.exe以及wsdl2h.exe，以及在/gSoap目录下的typemap.dat文件,将这些文件放到一个文件夹下。

二、对typemap.bat进行修改，

tds	= "http://www.onvif.org/ver10/device/wsdl"
tev	= "http://www.onvif.org/ver10/events/wsdl"
tls	= "http://www.onvif.org/ver10/display/wsdl"
tmd	= "http://www.onvif.org/ver10/deviceIO/wsdl"
timg	= "http://www.onvif.org/ver20/imaging/wsdl"
trt	= "http://www.onvif.org/ver10/media/wsdl"
tptz	= "http://www.onvif.org/ver20/ptz/wsdl"
trv	= "http://www.onvif.org/ver10/receiver/wsdl"
trc	= "http://www.onvif.org/ver10/recording/wsdl"
tse	= "http://www.onvif.org/ver10/search/wsdl"
trp	= "http://www.onvif.org/ver10/replay/wsdl"
tan	= "http://www.onvif.org/ver20/analytics/wsdl"
tad	= "http://www.onvif.org/ver10/analyticsdevice/wsdl"
tdn	= "http://www.onvif.org/ver10/network/wsdl"
tt	= "http://www.onvif.org/ver10/schema"

wsntw	= "http://docs.oasis-open.org/wsn/bw-2"
wsrfbf	= "http://docs.oasis-open.org/wsrf/bf-2"

#   WS-Discovery 1.0 remapping  
wsdd10__HelloType       = | wsdd__HelloType  
wsdd10__ByeType         = | wsdd__ByeType  
wsdd10__ProbeType       = | wsdd__ProbeType  
wsdd10__ProbeMatchesType    = | wsdd__ProbeMatchesType  
wsdd10__ProbeMatchType      = | wsdd__ProbeMatchType  
wsdd10__ResolveType     = | wsdd__ResolveType  
wsdd10__ResolveMatchesType  = | wsdd__ResolveMatchesType  
wsdd10__ResolveMatchType    = | wsdd__ResolveMatchType  
#   SOAP-ENV mapping  
SOAP_ENV__Envelope  = struct SOAP_ENV__Envelope { struct SOAP_ENV__Header *SOAP_ENV__Header; _XML SOAP_ENV__Body; }; | struct SOAP_ENV__Envelope  
SOAP_ENV__Header    = | struct SOAP_ENV__Header  
SOAP_ENV__Fault     = | struct SOAP_ENV__Fault  
SOAP_ENV__Detail    = | struct SOAP_ENV__Detail  
SOAP_ENV__Code      = | struct SOAP_ENV__Code  
SOAP_ENV__Subcode   = | struct SOAP_ENV__Subcode  
SOAP_ENV__Reason    = | struct SOAP_ENV__Reason

其中加色部分是添加的内容，用于对内容加上ONVIF的相关前缀，在通过soapcpp2.exe生成相关源文件之后，查看源代码可发现在代码上对这些改动的体现。

三、根据RemoteDiscovery.wsdl的到onvif.h文件

ONVIF官方文档，主要包含了函数的描述，SOAP Action，函数输入、输出接口等

Wsdl的资料在Onvif官方Wsdl文档中的ONVIF WSDL and XML Schemas Specifications一节，虽然可以全部下载为wsdl文件，但是wsdl文件中存在相互依赖的关系，并且是带有存储的依赖，所以一般最好直接使用url来产生头文件，不要下载下来。

官方2.0文档:   http://www.onvif.org/onvif/ver20/util/operationIndex.html  官方wsdl文档： http://www.onvif.org/Documents/Specifications.aspx

1.使用URL产生onvif.h：wsdl2h.exe -o onvif.h -c -s -t typemap.dat http://www.onvif.org/onvif/ver10/network/wsdl/remotediscovery.wsdl

2.使用本地文件产生onvif.h：wsdl2h.exe  -o  onvif.h  -s -t typemap.dat  remotediscovery.wsdl

其中-c为产生纯c代码，不然为c++代码；-s为不使用STL库，-t为typemap.dat的标识

四、根据onvif来产生相关源文件

soapcpp2.exe onvif.h -x -I E:\gsoap\import -I E:\gsoap

由于客户端主动发起Probe探针，所以只需产生客户端C代码，其中-x表示不产生xml文件，-I表示指定import路径。特别注意需要指定两个gsoap的两个目录，当中有产生源文件时所需的相关文件，如果不添加目录，也可在使用下面

soapcpp2.exe -x onvif.h

然后按照提示找到缺少的文件后添加到目录下。

五、完成main函数

#include <iostream>
#include "wsdd.nsmap"
#include "soapH.h"
using namespace std;
int main()
{
    struct soap *soap;
    struct wsdd__ProbeType req;
    struct __wsdd__ProbeMatches resp;
    struct wsdd__ScopesType sScope;
    struct SOAP_ENV__Header header;
    int count = 0;
    int result = 0; 

    char guid_string[100];

     soap = soap_new(); 
    if(soap==NULL)
    {
        return -1;
    }
 
    soap_set_namespaces(soap, namespaces); 

    soap->recv_timeout = 5;		//超过5秒钟没有数据就退出
    soap_default_SOAP_ENV__Header(soap, &header);
 
    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 = "";

    result = soap_send___wsdd__Probe(soap, "soap.udp://239.255.255.250:3702", NULL, &req);

    do{
         result = soap_recv___wsdd__ProbeMatches(soap, &resp); 
         if (soap->error) 
         { 
             cout<<"soap error:"<<soap->error<<soap_faultcode(soap)<<"---"<<soap_faultstring(soap)<<endl; 
             result = soap->error; 
             break;
         } 
         else
         {
            cout<<"========================================="<<endl;
 
            cout<<"Match size:"<<resp.wsdd__ProbeMatches->__sizeProbeMatch<<endl;
            cout<<"xsd-unsignedInt:"<<resp.wsdd__ProbeMatches->ProbeMatch->MetadataVersion<<endl;
            cout<<"scopes item:"<<resp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item<<endl;
            //cout<<"scopes matchby:"<<resp.wsdd__ProbeMatches->ProbeMatch->Scopes->MatchBy<<endl;
            cout<<"QName:"<<resp.wsdd__ProbeMatches->ProbeMatch->Types<<endl;
            cout<<"xsd:string:"<<resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.Address<<endl;
            cout<<"xsd:QName:"<<resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.PortType<<endl;
            cout<<"wsa:ServiceNameType:"<<resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.ServiceName<<endl;
            cout<<"sequence of elements:"<<resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.__size<<endl;
            cout<<"xsd:anyType:"<<resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.__anyAttribute<<endl;
            cout<<"endpoint any:"<<resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.__any<<endl;
            cout<<"wsdd:UriListType:"<<resp.wsdd__ProbeMatches->ProbeMatch->XAddrs<<endl;
         }
     }while(1);

    soap_destroy(soap); // remove deserialized class instances (C++ only) 
    soap_end(soap);		// clean up and remove deserialized data
    soap_done(soap);

    return result;
} 

六、结果

启动onvif的测试工具，点开Discovery，点击Discovery Device
