我们有支持ONVIF协议的网络IP摄像机。当我试图获得它的PTZ配置时,它会给出Auth错误。我正在C中执行此操作。以下是请求和响应。如何在ONVIF中验证用户?

请求:

"<?xml version=\"1.0\" encoding=\"UTF-8\"?>" 
    "<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\"" 
    "xmlns:tds=\"http://www.onvif.org/ver20/ptz/wsdl\">" 
    "<soap:Body>" 
    "<tds:GetNodes/>" 
    "</soap:Body>" 
    "</soap:Envelope>"

我如何验证用户?由于

问:你是否手工编写你的SOAP?问:相机型号和制造商是什么?他们是否支持一个接口库?或者任何规格(除了WSDL)?你有没有尝试联系他们(至少对于示例代码)? – paulsm4

它是佳能相机,VB-M40。这种认证方法在ONVIF程序员指南中给出。 “http://www.onvif.org/Portals/0/documents/WhitePapers/ONVIF_WG-APG-Application_Programmer%27s_Guide.pdf” –

需要认证的那些命令。他们的验证头可以像这样添加。

snprintf(postData, sizeof(postData), 
      "<?xml version=\"1.0\" encoding=\"utf-8\"?>" 
      "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://www.w3.org/2003/05/soap-envelope\"" 
      "xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401" 
      "-wss-wssecurity-secext-1.0.xsd\"" 
      "xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-" 
      "200401-wss-wssecurity-utility-1.0.xsd\"" 
      "xmlns:tds=\"http://www.onvif.org/ver20/ptz/wsdl\">" 
      "<SOAP-ENV:Header><wsse:Security><wsse:UsernameToken>" 
      "<wsse:Username>%s</wsse:Username>" 
      "<wsse:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-" 
      "200401-wss-username-token-profile-1.0#PasswordDigest\">" 
       "%s</wsse:Password><wsse:Nonce>%s</wsse:Nonce>" 
      "<wsu:Created>%s</wsu:Created></wsse:UsernameToken>" 
      "</wsse:Security></SOAP-ENV:Header><SOAP-ENV:Body>" 
      "<tds:GetNodes>" 
      "</SOAP-ENV:Body></SOAP-ENV:Envelope>", 
      username, base64EncDigest, nonce_char, time_char);

如何生成密码摘要?我正在浏览ONVIF程序员API,它看起来像是通过执行'Digest = B64ENCODE(SHA1(B64DECODE(Nonce)+ Date + Password))'生成的,但日期和密码都是已转换为二进制文件。将字符串转换为二进制文件意味着什么?你是如何生成摘要的? – CadentOrange

nonce_char应该是base64编码的?什么是time_char?是时间戳还是现在时间,比如2014-01-02T12:47:08Z – kashifmehmood

您可以使用gSOAP的与WSSE插件生成的,你需要ONVIF WDSL C++客户端代理。

这样做是否大大简化了我的工作。以下是调用GetVideoEncoderConfiguration并读取响应的示例。

_media__GetVideoEncoderConfigurations query; 
_media__GetVideoEncoderConfigurationsResponse response; 

soap_wsse_add_Security(&mediaProxy); 
soap_wsse_add_UsernameTokenDigest(&mediaProxy, NULL, m_username.c_str(), m_password.c_str()); 

if(mediaProxy.GetVideoEncoderConfigurations(&query, &response) == SOAP_OK) 
{ 
    LogSuccess("GetVideoEncoderConfigurations"); 
    for(auto it = response.Configurations.begin(); it != response.Configurations.end(); ++it) 
    { 
     onvif__VideoEncoderConfiguration* videoConf = *it; 
     log(I3) << "Name= " << videoConf->Name << ", Encoding=" << videoConf->Encoding << ", Resolution=" << videoConf->Resolution->Width << "x" << videoConf->Resolution->Height; 
    } 
} 
else 
    LogError("GetVideoEncoderConfigurations", soap_faultdetail(&mediaProxy)); 

所以没有手动创建肥皂消息。 gSOAP生成的代码会在较低层处理此问题。当然,需要2天才能生成wsse支持的工作代码,但仍然可以快10倍。如果您有兴趣了解更多信息,请联系我。
