Http Kerberos authentication

Recommended Posts

Does LabVIEW support kerberos authentication? If someone has worked in this, a snippet on how to do authentication would be of very much help. Any help in this regard is appreciated.

LabView doesn't have built in VI's for Kerberos authentication. What platform do you use?

      Hello
       
      I have a problem with http VI’s and external web services (RESTful) and I’m using LabVIEW 2013.
       
      In NetBeans I create a project with a GET web service from a table in MySQL, so I use http VI’s for accessing the service (blog diagram .png), receiving the information in JSON (front panel.png) and took the information I needed (in this case the “slActualValue†value).
       
      I have a program that inserts new values in the database and in chrome the service works fine but if a want to do the Vi in a while loop to update or receive new values, the the next JSON data form the web service is the same as the first call, but if I go to the NetBeans project and do the deploy again the JSON data changes.
       
      I ask about this problem from the experts in web services (RESTful) and they say that is the cookies in the LabVIEW program, so I create add a cookie file .txt but im not confident about the format of the file(the example is in this post) or if there something amiss in the LabVIEW VI’s
       
      Cookie.txt file
      # Netscape HTTP Cookie File
      # http://curl.haxx.se/rfc/cookie_spec.html
      # This file was generated by libcurl! Edit at your own risk.

      Hi Guys,
       
      It has been a while but I'm back :-)
       
      I'm having some 'problems' with http requests ....
       
      Project summary:
      LabVIEW 2010 Application that reads sensor logs from a database.
       
      The application gets its data via http requests: --> architecture of the project --> data must be accessible via web-service 
       
      Example: http://localhost:8085/sensorservice/sensor/test/temperature..... (and some paramaters about the amount of data to return.) is entered in the LabVIEWHTTPClient.lvlib:GET.vi and I receive my data in the body and header controls.
       
      So far so good.
       
      Every data request takes about 0.3 s Not bad .... but .... all sensors that are read in the application are handled sequentially in a FOR loop.  So 60 sensors *0.3s == 18s update rate.
      Not fast enough for my customer.
       
      The LabVIEWHTTPClient.lvlib:GET.vi is reentrant and it allocates an instance for each clone.  
       
      So i quickly made an active object for each sensor and call the LabVIEWHTTPClient.lvlib:GET.vi by ref with x08 as option when i open the vi ref.
       
      It returns the data BUT ... requests are still sequential and not parallel :-(  
       
      LabVIEWHTTPClient.lvlib:GET.vi blockdiagram is protected with a password, but I assume it still blocks because of a dll call.
       
      Did anyone make an application with parallel http requests ?
       
      Thx.
       
      Wim
