Automatic refresh a Bearer ACCESS TOKEN in inputs.http

[JornDL]

Feature Request

Make it possible to refresh a Bearer ACCESS TOKEN in inputs.http

Opening a feature request kicks off a discussion.

Proposal:

To make this possible in inputs.http:

Current behavior:

[[inputs.http]]
urls = ["https://api.netatmo.com/api/gethomecoachsdata?device_id=MAC-ADDRESS"]
headers = {"accept" = "application/json"}
headers = {"Authorization" = "Bearer ACCESS TOKEN"}

This works fine as long as the Bearer ACCESS TOKEN has not expired

Desired behavior:

Automatic refresh of the Bearer ACCESS TOKEN so it does not expire

Use case:

All cases where the Bearer ACCESS TOKEN expires.

Example from Netatmo:

Hi @JornDL the bearer_token is read from file at every gather interval. So if you make sure that file is updated on time, telegraf will continue to work.

Hi @Hipska

Can you help me on how to do that, please.

Updating a file?

It seems like it isn't even needed when I look at your initial description. It appears that You want to use an Oauth2 service:

  ## OAuth2 Client Credentials. The options 'client_id', 'client_secret', and 'token_url' are required to use OAuth2.
  client_id = "clientid"
  client_secret = "secret"
  token_url = "https://api.netatmo.com/oauth2/token"
  # scopes = ["urn:opc:idm:__myscopes__"]

Hi @Hipska

I don't think that you read all my first mail, because

To get access the user has to do a POST to receive an access token and refresh token from Netatmo.

As they they are only valid for a certain time period, the user has to renew them from time to time.

To gather data the user has to do a GET with just the device_id and the access token.

I had to write my own bash script to receive and renew my access tokens, as Telegraf inputs.http can't do it.
I found inspiration from this guy: https://mike-greene.com/blog/2019/1/21/analyzing-fitbit-data-with-telegraf-grafana

This issue merits revisit, as there are other REST API's out there that expire tokens at regular intervals. Telegraf should have a mechanism for renewing the bearer token.

[PaJaSoft]

There are more APIs (e.g. WeatherXM) which work similarly and can't be used in HTTP input plugin by convenient way when Bearer token refreshing isn't supported...

Can't reopen this issue, so create a new one here, feel free to jump-in and help me to convince developers that this is an important part of the HTTP plugin features set.
