Azure Functions本地运行时无法禁用SDK HTTP日志，如何解决？

问题 #

本地运行Azure Functions时，会输出大量不需要的HTTP请求与响应日志，示例如下：

已尝试通过客户端初始化参数禁用日志，但无效：

client = SecretClient(vault_url=KVUri, credential=credential, logging=False)
....
# upload file to share
file_client = ShareFileClient.from_connection_string(
    conn_str='xxx',
    share_name=container_name,
    file_path=file_name,
    logging_enable=False,
)

需求：保留应用内自定义日志（如logging.info('example message')），禁用上述HTTP请求/响应日志。

解决方案 #

这些HTTP日志来自Azure Python SDK的底层日志器，需通过Python标准logging模块调整特定日志器的级别来禁用：

• 针对Azure Key Vault SDK：调整azure.keyvault.secrets和azure.core.pipeline.policies.http_logging_policy的日志级别至WARNING或更高
• 针对Azure Storage SDK：调整azure.storage.fileshare和azure.core.pipeline.policies.http_logging_policy的日志级别至WARNING或更高

在Function的初始化代码（如__init__.py或函数文件开头）添加以下配置：

import logging

# 禁用Azure SDK的HTTP详细日志
logging.getLogger("azure.keyvault.secrets").setLevel(logging.WARNING)
logging.getLogger("azure.storage.fileshare").setLevel(logging.WARNING)
logging.getLogger("azure.core.pipeline.policies.http_logging_policy").setLevel(logging.WARNING)

# 确保自定义日志正常输出（可根据需求调整级别）
logging.basicConfig(level=logging.INFO)

说明 #

• 上述配置仅限制Azure SDK的HTTP请求/响应日志输出，不影响自定义的logging.info/debug等日志
• 如果还有其他Azure服务的HTTP日志，可对应添加该服务的日志器（如azure.cosmos、azure.eventhub等）并设置级别为WARNING
