示例1: inject_assume_role_provider_cache
# 需要导入模块: from botocore import credentials [as 别名]
# 或者: from botocore.credentials import JSONFileCache [as 别名]
def inject_assume_role_provider_cache(session, **kwargs):
try:
cred_chain = session.get_component('credential_provider')
except ProfileNotFound:
# If a user has provided a profile that does not exist,
# trying to retrieve components/config on the session
# will raise ProfileNotFound. Sometimes this is invalid:
#
# "ec2 describe-instances --profile unknown"
#
# and sometimes this is perfectly valid:
#
# "configure set region us-west-2 --profile brand-new-profile"
#
# Because we can't know (and don't want to know) whether
# the customer is trying to do something valid, we just
# immediately return. If it's invalid something else
# up the stack will raise ProfileNotFound, otherwise
# the configure (and other) commands will work as expected.
