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!
