禁用查询记录 - Google Appengine SDK Python

Question

我遇到的情况是我有一个调用logging.debug(xxx)的包.我想通过此包禁用所有日志记录语句.有没有办法通过配置来做到这一点？

例如,我运行的每个查询都在dev服务器的控制台中打印出来:

DEBUG:root:SELECT实体.path,Entities.entity FROM"dev~xxxx !! Entities"AS实体INNER JOIN"dev~xxxx !! EntitiesByProperty"AS ebp_0 ON实体.path = ebp_0.路径 INNER JOIN"dev~xxxx !! EntitiesByProperty"AS ebp_1 ON实体.path = ebp_1.路径 INNER JOIN"dev~xxxx !! EntitiesByProperty"AS ebp_2 ON实体.path = ebp_2.path WHERE ebp_0.kind =:1 AND ebp_0.name =:2 AND ebp_0.value =:3 AND ebp_1.kind =:4 AND ebp_1.name =:5 AND ebp_1.value =:6 AND ebp_2.kind =:7 AND ebp_2.name =:8 AND ebp_2.value =:9 ORDER BY实体.路径 ASC

所以我知道如何通过修改sdk源来禁用它,基本上注释掉日志语句 __StarSchemaQueryPlan

logging.debug(query)

有没有办法在不触及SDK代码的情况下禁用日志记录？我们目前没有定义任何loggingConfigurations,并且正在使用basicConfiguror.

最后的解决方案谢谢@lucemia:

class Filter(object):
    def filter(self, record):
        if record.funcName=='__StarSchemaQueryPlan' and record.module=='datastore_sqlite_stub':
            return 0
        else:
            return 1

Answer 1

您可以尝试修改日志级别.

由于该模块使用默认记录器.以下代码将禁用所有级别小于严重级别的日志.

import logging
logger = logging.getLogger() # get the default logger
logger.setLevel(50) # set the skip all log which is smaller than critical (50)

测试用例

a_lib.py

import logging

def main():
    logging.error("test")
    logging.critical('c')

a_test_case.py

import a_lib
import logging

logger = logging.getLogger()
logger.setLevel(50)
a_lib.main()

结果

> python a_test.py
CRITICAL:root:c

另一种方法是使用过滤器

import logging

# define a new filter
class Filter():
    def filter(self, record):
        # extract property of record such as record.funcName, record.module
        # http://docs.python.org/2/library/logging.html#logrecord-attributes


        if record.module == "a_lib":
            # if the record is from a module you don't want to log
            return 0
        else:
           # for record you want to log
            return 1



 # apply this filter

 filter = Filter()
 logger= logging.getLogger()
 logger.addFilter(filter)
