onvif開發之裝置發現功能的實作--轉

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:

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:

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;

onvif開發之裝置發現功能的實作--轉

    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。
