Authentication example
|
|
|
|
To authenticate you must have the environment variables set or use the
|
|
command line options. This is a good example to start wtih because once
|
|
you know you can authenticate, you can perform other operations that
|
|
require authentication. Refer to the example common.py for the environment
|
|
variables or command line options to use.
|
|
|
|
If you use the environment variables, authenticate with:
|
|
|
|
python -m examples.authenticate
|
|
