LV 2011 , OSX 10.7.5.
So I've got a URL to fetch some json data, works with curl from a shell :
curl "http://mst-log.physics.wisc.edu/logbook.py/RPC?json=\{%22function%22:%22fetchTimeLogLatest%22,%22params%22:\{%22group%22:%22ops%22,% 20%22logName%22:%22tank_temps%22\}\}"
(returns a json structure you can parse as a string)
( wont' work for you, er , better not work for you, outside our firewall ! 😉 )
Just feeding the URL above from "mst-log..." ought to just work with GET.vi, no ? but Labview does strange things.
I can get to the remote server logs and see that labview converts some characters when I tried that:
[01/Nov/2012:11:31:50 -0500] "GET /logbook.py/RPC?json=%5c%7b%22function%22:%22fetchTimeLogLatest%22,%22params%22 :%5c%7b%22group%22:%22ops%22,%20%22logName%22:%22tank_temps%22%5c%7d%5c%7d HTTP/1.1" 500 1654 "-" "National Instruments LabVIEW"
Next, tried sending this to url-encode_string.vi but the vi only returns "mst-" and nothing else. the GET.vi then throws a "no network" error.
Couple more trials with substituting %xx equivalents into the original string , where the access.log showed LV changing things yields "interesting" results.
Can still do it calling curl externally, but surely this should work, no ?
