Exception Handling
Last Updated：2020-07-20
BMR provides the following ways of exception attention as follows:
| Exceptional Method | Description |
|---|---|
| BceHttpClientError | Exception occurred in retry |
| last_error | Exception occurred in last retry |
| BceClientError | BMR client exception |
| BceInvalidArgumentError | Exception occurred in passing parameters |
| BceServerError | BMR server exception |
You can use “try” to obtain the event exception:
from baidubce.exception import BceHttpClientError
from baidubce.exception import BceServerError
try:
response = bmr_client.get_step(new_cluster_id, step_id)
LOG.debug('describe steps response: %s' % response)
except BceHttpClientError as e:
if isinstance(e.last_error, BceServerError):
LOG.error('get_step failed. Response %s, code: %s, msg: %s'
% (e.last_error.status_code, e.last_error.code, e.last_error.message))
else:
LOG.error('get_step failed. Unknown exception: %s' % e)
