[Ovmsdev] Historical data download tool

[Michael Balzer]

Users are having issues downloading CSV telemetry data from the 
openvehicles.com server.

On my server, CSV tables can be downloaded directly from the vehicle 
page. Unfortunately I cannot provide a similar feature for the Drupal 
module, as I've never used Drupal.

As a workaround I have implemented a simple download tool for other servers:

https://dexters-web.de/downloadtool

The tool uses the HTTP(S) API, and adds known headers automatically.

Forum thread: https://www.openvehicles.com/node/2832

FYI: the JSON to CSV step is done using "jq":

curl -s -X GET -b $(_tmpdir)/.cookiejar 
"$(_server2)/api/historical/$(URL:_vehicleid)/$(URL:_type)" \
  | jq -r 'map([(.h_timestamp|tostring), (.h_recordnumber|tostring), 
(.h_data|tostring)] | join(",")) | join("\n")'

Regards,
Michael
