This article introduces example code and sample log content for enabling the Python SDK.
Log Format
The Python SDK logging feature collects various operation logs for TOS and stores them locally as files. The log format is as follows.
<time><python file name><level><threadId><message>
Enable Python SDK Logging
The following code demonstrates how to enable logging for the Python SDK.
# -*- coding: utf-8 -*-
import logging
import os
import tos
# The following code demonstrates the enablement of logging feature in Python SDK.
# The complete file path for the log, for example /usr/local/TosClient.log
log_file_path = 'your fog file path'
# Set the log level and log file storage address for the TOS Python SDK using tos.set_logger.
# file_path is the complete file path of the log file.
# format_string is the defined log format.
# level is the log level, with the default being INFO.
# During development and testing, the log level can be set to logging.DEBUG.
tos.set_logger(file_path=log_file_path, level=logging.INFO)
# Get AK and SK information from environment variables.
ak = os.getenv('TOS_ACCESS_KEY')
sk = os.getenv('TOS_SECRET_KEY')
endpoint = 'your endpoint'
region = 'your region'
bucket_name = 'your bucket name'
object_key = 'your object key'
# Create a TosClientV2 object to perform operations on buckets and objects.
client = tos.TosClientV2(ak, sk, endpoint, region)
# Create bucket
client.create_bucket(bucket_name)
# Add an object to the bucket.
client.put_object(bucket_name, object_key, content='测试一下')
Log Content Example
When using the default log format, the log content is as follows.
