忙了一個多月,onvif總算告一段落了。這幾個星期忙着其他的項目,也沒有好好整理一下onvif的東西。接下來得好好整理一下自己的項目思路和項目經驗,同時将自己的一些心得寫出來,希望對人有所幫助。
相信大多數兄弟和我一樣,onvif開發,最開始做的就是發現功能。這兩天登入onvif的官網看才發現,onvif版本在八月份有更新,已經更新到V2.4了,于是下載下傳最新的版本來進行。代碼的生成可以詳見我的前一篇文章。V2.4版本新增了一個wsdl檔案,現在用于生成源碼的檔案一共有18個。為了保證全功能,最好一次性生成包含所有功能的源碼。然後根據最新生成的源碼來實作onvif用戶端和服務端的發現功能。
1. 建立onvif_test目錄。以下這些源碼由最新的gsoap(2.8.16)和最新的onvif的wsdl檔案(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.以下檔案來自gsoap_2.8.16\gsoap-2.8\gsoap
stdsoap2.c
stdsoap2.h
3.以下檔案來自gsoap_2.8.16\gsoap-2.8\gsoap\custom
duration.c
4.生成的soapClientLib.c和soapServerLib.c無實際作用,可直接删除。
5.增加自定義檔案:
onvif_server.c onvif服務端實作代碼
onvif_client.c onvif用戶端實作代碼
onvif_server_interface.c onvif服務端接口實作
onvif_function.c onvif實作函數,公用
onvif_function.h onvif實作函數,公用
onvif_server.c為服務端的實作代碼,主要是定義main函數,服務端主要是監聽,并處理和應答消息。
Main函數定義如下:
int main(int argc,char ** argv)
{
printf("[%s][%d][%s][%s] start \n", __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 \n", __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\n",errno,strerror(errno));
return 0;
for(;;)
if(soap_serve(&ServerSoap))
{
soap_print_fault(&ServerSoap, stderr);
}
soap_destroy(&ServerSoap);
soap_end(&ServerSoap);
//用戶端的IP位址
printf("RECEIVE count %d, connection from IP = %lu.%lu.%lu.%lu socket = %d \r\n", count, ((ServerSoap.ip)>>24)&0xFF, ((ServerSoap.ip)>>16)&0xFF, ((ServerSoap.ip)>>8)&0xFF,(ServerSoap.ip)&0xFF, (ServerSoap.socket));
count++;
//分離運作時的環境
soap_done(&ServerSoap);
return 0;
}
onvif_server_interface.c 此檔案用來定義所有服務端需要填充的接口。這裡我們填充__wsdd__Probe接口即可,其他贊不支援的接口可以用宏統一處理。
__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

netGetMac("eth4", macaddr); //eth0 根據實際情況填充

unsigned int localIp = 0;
netGetIp("eth4", &localIp); //eth0 根據實際情況填充
sprintf(_IPAddr, "http://%s/onvif/device_service", inet_ntoa(*((struct in_addr *)&localIp)));
printf("[%d] _IPAddr ==== %s\n", __LINE__, _IPAddr);
ProbeMatches.__sizeProbeMatch = 1;

strcpy(ProbeMatches.ProbeMatch->wsa__EndpointReference.Address, _HwId);
soap->header->wsa__To = "http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous";

printf("[%d] soap error: %d, %s, %s\n", __LINE__, soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
return soap->error;;
onvif_client.c onvif用戶端實作代碼,主要是定義用戶端的main函數:
Main定義如下:
int main()
{
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\r\n");
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\n", soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
result = soap->error;
}
else
printf("guog *********************************************\r\n");
if(soap->header->wsa__MessageID)
{
printf("MessageID : %s\r\n", soap->header->wsa__MessageID);
}
if(soap->header->wsa__RelatesTo && soap->header->wsa__RelatesTo->__item)
printf("RelatesTo : %s\r\n", soap->header->wsa__RelatesTo->__item);
if(soap->header->wsa__To)
printf("To : %s\r\n", soap->header->wsa__To);
if(soap->header->wsa__Action)
printf("Action : %s\r\n", soap->header->wsa__Action);
for(i = 0; i < resp.wsdd__ProbeMatches->__sizeProbeMatch; i++)
printf("__sizeProbeMatch : %d\r\n", resp.wsdd__ProbeMatches->__sizeProbeMatch);
printf("wsa__EndpointReference : %p\r\n", resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference);
printf("Target EP Address : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.Address);
printf("Target Type : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->Types);
printf("Target Service Address : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->XAddrs);
printf("Target Metadata Version : %d\r\n", resp.wsdd__ProbeMatches->ProbeMatch->MetadataVersion);
if(resp.wsdd__ProbeMatches->ProbeMatch->Scopes)
{
printf("Target Scopes Address : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item);
}
}
}
else if (soap->error)
printf("[%d] soap error 2: %d, %s, %s\n", __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 !\n", __LINE__);
return result;
}
6.将wsdd.nsmap改為nsmap.h,并删除其餘的*.nsmap(都一樣)
7.編寫makefile檔案。注意在makefile中打開開關DEBUG,以便跟蹤日志。
8.tcpdump為gcc環境的抓包工具,調試的時候用。
make編譯通過,運作,用戶端發現功能ok;
但是服務端的發現功能卻不行;别急,這是由于SOAP的版本問題;soap的版本是根據命名空間來自動确定的;在soap結構體的version字段表示soap版本;
以下命名空間表示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
以下命名空間表示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
注意确定自己目前的命名空間。我們用SOAP1.2版本才能被測試工具發現(ONVIF Device Test Tool version 13.06)。
不清楚可以檢視soap_set_namespaces接口和soap_set_local_namespaces接口;
于是将nsmap.h中的命名空間前兩行改為:
再編譯運作,發現功能ok。
最後,将所用的工具和源碼提供給大家,大家根據需要下載下傳。
