添加相关信息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" # OASISrecommendedprefixeswsnt  ="http://docs.oasis-open.org/wsn/b-2"wsntw ="http://docs.oasis-open.org/wsn/bw-2"wsrfbf="http://docs.oasis-open.org/wsrf/bf-2"wsrfr ="http://docs.oasis-open.org/wsrf/r-2"wsrfrw ="http://docs.oasis-open.org/wsrf/rw-2"wstop ="http://docs.oasis-open.org/wsn/t-1" #  WS-Discovery1.0remapping 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-ENVmapping SOAP_ENV__Envelope =structSOAP_ENV__Envelope{structSOAP_ENV__Header*SOAP_ENV__Header;_XMLSOAP_ENV__Body;};|structSOAP_ENV__Envelope SOAP_ENV__Header   =|structSOAP_ENV__Header SOAP_ENV__Fault    =|structSOAP_ENV__Fault SOAP_ENV__Detail   =|structSOAP_ENV__Detail SOAP_ENV__Code     =|structSOAP_ENV__Code SOAP_ENV__Subcode  =|structSOAP_ENV__Subcode SOAP_ENV__Reason   =|structSOAP_ENV__Reason 2)        wsa5.h中无SOAP_ENV__Fault函数由于wsa5.h中没有SOAP_ENV__Fault因此不会产生代码重复，因此不用注释。 二、新建工程,调试代码1.        新建一个项目将上面生成的soapH.h、soapStub.h、wsdd.nsmap、soapC.c、soapClient.c，还有位于gsoap-2.8\gsoap的:stdsoap2.c、stdsoap2.h和位于\custom中的:duration.c放入工程中，然后编写main函数,调试代码。2.        文件主要功能说明wsdd.nsmap    名空间定义，服务器端与客户端都要包含它,里面有很多,都是      相同的,只需导入一个进入工程就行stdsoap2.h       Header_leofstdsoap2.cppruntimelibrarystdsoap2.c      RuntimeClibrarywithXMLparserandrun-timesupportroutinessoapStub.h      soapH.h        //MainheaderfiletobeincludedbyallclientandservicesourcessoapC.c       //SerializersanddeserializersforthespecfieddatastructuressoapClient.c   //Clientstubroutinesforremoteoperations  soapStub.h      Amodi_edandannotatedheaderfileproducedfromtheinputheaderfile 三、设备发现main函数说明#include<iostream>#include"wsdd.nsmap"#include"soapH.h"usingnamespacestd;int main(){   /*****声明变量***********/     structsoap*soap;              //soap环境变量     structwsdd__ProbeTypereq;      //客户端发送的Probe     struct__wsdd__ProbeMatchesresp; //服务端回的Probematchs     structwsdd__ScopesTypesScope;   //Probe里面的范围     structSOAP_ENV__Headerheader;   //SOAP的头     intresult=0;                   //返回值             int count=0;                   //获得的设信息备个数        /**获取guid(windows下叫guid,linux下叫uuid),为urn:uuid:8-4-4-4-12,由系统随机产生**/    staticcharbuf[64]={0};  //用来保存guid号       GUIDguid;     /*声明guid为GUID结构体变量,包含4个变量,分别是                   unsignedlongData1;                 unsignedshortData2;                 unsignedshortData3;                 unsignedchar Data4[8];                     */if (S_OK==CoCreateGuid(&guid))    //如果guid生成成功,则将其转为字符串,保存在buf中{     _snprintf(buf,sizeof(buf)     ,"urn:uuid:%08X-%04X-%04x-%02X%02X-%02X%02X%02X%02X%02X%02X"     ,guid.Data1     ,guid.Data2     ,guid.Data3     ,guid.Data4[0],guid.Data4[1]     ,guid.Data4[2],guid.Data4[3],guid.Data4[4],guid.Data4[5]     ,guid.Data4[6],guid.Data4[7]     );    }soap=soap_new(); //初始化soap    if(soap==NULL)    {        return -1;    }      soap_set_namespaces(soap,namespaces);    //设置命名空间    soap->recv_timeout=5;     //设置接收Probematchs时间,超过5秒钟没有数据就退出soap_default_SOAP_ENV__Header(soap,&header);   //将header设置为soap消息的头属性/*****给头赋值******/    header.wsa__MessageID=buf;                         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;     /*设置所需寻找设备的类型和范围,二者至少设定一个,否则可能收到非ONVIF设备,出现异常*/    soap_default_wsdd__ScopesType(soap,&sScope);    sScope.__item="onvif://www.onvif.org";     //设置所需设备的sScope    soap_default_wsdd__ProbeType(soap,&req);         req.Scopes=&sScope;    req.Types="tdn:NetworkVideoTransmitter";    /*设置所需设备的类型,tdn为命名空间前缀,为wsdd.nsmap文件中{"tdn","http://www.onvif.org/ver10/network/wsdl"}的tdn,如过不是tdn,而是其它,如ns1这里也要随之改为ns1*/      //通过组播发送Probe探针,发送成功返回0,否则-1result=soap_send___wsdd__Probe(soap,"soap.udp://239.255.255.250:3702",NULL,&req);     if(result==-1)    {  cout<<"soaperror:"<<soap->error<<soap_faultcode(soap)<<"---"<<soap_faultstring(soap)<<endl;     }else                   {        do{              result=soap_recv___wsdd__ProbeMatches(soap,&resp);//接收ProbeMatches,成功返回0,否则-1              if (r
