Python如何使用logging為Flask增加logid

import threading
 
from blueprint.hooks import hooks
 
thread_local = threading.local()
app = Flask()
app.thread_local = thread_local

import uuid
 
from flask import Blueprint
from flask import current_app as app
 
hooks = Blueprint('hooks', __name__)
 
@hooks.before_app_request
def before_request():
    """
    處理請求之前的鉤子
    :return:
    """
    # 生成logid
    app.thread_local.logid = uuid.uuid1().time

import logging
 
# https://docs.python.org/3/library/logging.html#logrecord-attributes
log_format = "%(asctime)s %(levelname)s [%(threadName)s-%(thread)d] %(logid)s %(filename)s:%(lineno)d %(message)s"
file_handler = logging.FileHandler(file_name)
logger = logging.getLogger()
logid_filter = ContextFilter()
file_handler.addFilter(logid_filter)
file_handler.setFormatter(logging.Formatter(log_format))
logger.addHandler(file_handler)
 
class ContextFilter(logging.Filter):
    """
    logging Filter
    """
 
    def filter(self, record):
        """
        threading local 獲取logid
        :param record:
        :return:
        """
        log_id = thread_local.logid if hasattr(thread_local, 'logid') else '-'
        record.logid = log_id
 
        return True
