How to use json to get data from MPBM.It would have saved me quite a few hours if an example of this type had been available, so, here it is for anyone else who might be looking.
The 'magic' involved is having to set the headers on the request in order to receive a non-null response.
E.g.,
curl <url> -d "1" -H "DNT: 1" -H "If-Modified-Since:Sat, 1 Jan 2000 00:00:00 GMT" -H "Content-Type:application/json"
You can find examples of required <url> in the Python example below.
This gives a quick test to ensure the web-server / mpbm is working before you get bogged down in "why is urllib3 throwing that exception?".
(BTW, "requests" is a third party library. Free to use it seems. You can find it if you need it.)
