login: Function to login to a specific backend

In flahn/openeo-r-client: openEO client interface

Description

Retrieves the bearer-token from the backend by sending user name and password to the backend. This step is usually also performed in the 'connect' step. But if you only connected to a back-end in order to explore the functionalities and want to compute something, then you need to log in afterwards.

Usage

login(
  user = NULL,
  password = NULL,
  login_type = NULL,
  provider = NULL,
  config = NULL,
  con = NULL
)

Arguments

user	the user name
password	the password
login_type	either NULL, 'basic' or 'oidc'. This refers to the login mechanism that shall be used. NULL disables authentication.
provider	provider object as obtained by 'list_oidc_providers()'
config	named list containing 'client_id' and 'sercret' or a path to the configuration file (type JSON)
con	connected back-end connection (optional) otherwise active_connection is used.

Value

a connected and authenticated back-end connection

Examples
