【已解决】Flask中logging的单例初始化出错:AttributeError: ‘Formatter’ object has no attribute find

折腾:

【已解决】把Flask中的app的logger改造成单例以避免循环引用和多次初始化Flask的实例

期间,之前是Flask的app.logger的初始化:

def create_log(app):

    print("create_log: before init log: app.logger=%s" % app.logger)

    logFormatter = logging.Formatter(settings.LOG_FORMAT)

    fileHandler = RotatingFileHandler(

        settings.LOG_FILE_FILENAME,

        maxBytes=settings.LOG_FILE_MAX_BYTES,

        backupCount=settings.LOG_FILE_BACKUP_COUNT,

        encoding="UTF-8")

    fileHandler.setLevel(settings.LOG_LEVEL)

    fileHandler.setFormatter(logFormatter)

    app.logger.addHandler(fileHandler)

    # Note: should NOT set StreamHandler here, otherwise will duplicate debug log

    app.logger.setLevel(settings.LOG_LEVEL)  # set root log level

    log = app.logger

    log.info("app=%s", app)

    # log.debug("app.config=%s", app.config)

    print("create_log: after init log: app.logger=%s" % app.logger)

    return log

是没问题的:

log尽可以输出到file文件,也可以输出到console中

现在去改为:

common/FlaskLogSingleton.py

import logging

from logging.handlers import RotatingFileHandler

from conf.app import settings

from common.ThreadSafeSingleton import ThreadSafeSingleton

def init_logger(flask_settings, enableConsole=True):

    print("init_logger")

    flaskAppLogger = logging.getLogger(flask_settings.FLASK_APP_NAME) # <Logger RobotQA (WARNING)>

    print("flaskAppLogger=%s" % flaskAppLogger)

    logFormatter = logging.Formatter(flask_settings.LOG_FORMAT)

    fileHandler = RotatingFileHandler(

        flask_settings.LOG_FILE_FILENAME,

        maxBytes=flask_settings.LOG_FILE_MAX_BYTES,

        backupCount=flask_settings.LOG_FILE_BACKUP_COUNT,

        encoding="UTF-8")

    fileHandler.setLevel(flask_settings.LOG_LEVEL_FILE)

    fileHandler.setFormatter(logFormatter)

    flaskAppLogger.addHandler(fileHandler)

    # Note: should NOT set StreamHandler here, otherwise will duplicate debug log

    flaskAppLogger.setLevel(flask_settings.LOG_LEVEL_FILE)  # set root log level

    if enableConsole :

        # define a Handler which writes INFO messages or higher to the sys.stderr

        console = logging.StreamHandler()

        console.setLevel(flask_settings.LOG_LEVEL_CONSOLE)

        # set a format which is simpler for console use

        formatter = logging.Formatter(

            # fmt=logFormatter)

            fmt=logFormatter,

            datefmt=flask_settings.LOG_CONSOLE_DATA_FORMAT)

        # tell the handler to use this format

        console.setFormatter(formatter)

        flaskAppLogger.addHandler(console)

    print("init_logger: after init flaskAppLogger%s" % flaskAppLogger)

    return flaskAppLogger

class LoggerSingleton(metaclass=ThreadSafeSingleton):

    curLog = ""

    def __init__(self):

        self.curLog = init_logger(settings)

        # Note: during __init__, AVOID use log, otherwise will deadlock

        # log.info("LoggerSingleton __init__: curLog=%s", self.curLog)

        print("LoggerSingleton __init__: curLog=%s" % self.curLog)

logSingleton = LoggerSingleton()

log = logSingleton.curLog

log.info("LoggerSingleton inited, logSingleton=%s", logSingleton) # <factory.LoggerSingleton object at 0x10cbcafd0>

log.info("log=%s", log) # <Logger RobotQA (DEBUG)>

# # debug for singleton log

# log2 = LoggerSingleton()

# print("log2=%s" % log2)

其中配置是:

conf/app/settings.py

# Flask app name

FLASK_APP_NAME = "RobotQA"

# Log File

LOG_LEVEL_FILE = logging.DEBUG

LOG_FILE_FILENAME = "logs/" + FLASK_APP_NAME + ".log"

LOG_FORMAT = "[%(asctime)s %(levelname)s %(filename)s:%(lineno)d %(funcName)s] %(message)s"

LOG_FILE_MAX_BYTES = 2 * 1024 * 1024

LOG_FILE_BACKUP_COUNT = 10

# Log Console

LOG_LEVEL_CONSOLE = logging.INFO

LOG_CONSOLE_DATA_FORMAT = ‘%Y%m%d %I:%M:%S’

结果是可以输出到文件的,但是输出到console时出错:

去搜:

python logging console AttributeError: ‘Formatter’ object has no attribute ‘find’

Python logging module having a formatter causes AttributeError – Stack Overflow

去加上:

from sys import stdout

试试:

from sys import stdout

console = logging.StreamHandler(stdout)

调试:

结果:问题依旧。

另外,上面代码是参考自己之前的代码:

难道只是此处的LoggerSingleton是特殊的单例,而导致无法正常在console中输出?

看看后续普通的变量能否正常输出

问题依旧:

pycharm console StreamHandler  AttributeError: ‘Formatter’

python self._fmt.find(self.asctime_search)

再去看代码,感觉是代码搞错了,改为:

# fmt=logFormatter,

fmt=flask_settings.LOG_FORMAT,

变成:

LOG_FORMAT = "[%(asctime)s %(levelname)s %(filename)s:%(lineno)d %(funcName)s] %(message)s"

def init_logger(flask_settings, enableConsole=True):

    print("init_logger")

    flaskAppLogger = logging.getLogger(flask_settings.FLASK_APP_NAME) # <Logger RobotQA (WARNING)>

    print("flaskAppLogger=%s" % flaskAppLogger)

    flaskAppLogger.setLevel(flask_settings.LOG_LEVEL_FILE)

    logFormatter = logging.Formatter(flask_settings.LOG_FORMAT)

    fileHandler = RotatingFileHandler(

        flask_settings.LOG_FILE_FILENAME,

        maxBytes=flask_settings.LOG_FILE_MAX_BYTES,

        backupCount=flask_settings.LOG_FILE_BACKUP_COUNT,

        encoding="UTF-8")

    fileHandler.setLevel(flask_settings.LOG_LEVEL_FILE)

    fileHandler.setFormatter(logFormatter)

    flaskAppLogger.addHandler(fileHandler)

    if enableConsole :

        # define a Handler which writes INFO messages or higher to the sys.stderr

        console = logging.StreamHandler()

        # console = logging.StreamHandler(stdout)

        console.setLevel(flask_settings.LOG_LEVEL_CONSOLE)

        # set a format which is simpler for console use

        formatter = logging.Formatter(

            # fmt=logFormatter)

            # fmt=logFormatter,

            fmt=flask_settings.LOG_FORMAT,

            datefmt=flask_settings.LOG_CONSOLE_DATA_FORMAT)

        # tell the handler to use this format

        console.setFormatter(formatter)

        flaskAppLogger.addHandler(console)

    print("init_logger: after init flaskAppLogger%s" % flaskAppLogger)

    return flaskAppLogger

结果:

终于可以正常输出了:

【总结】

此处是不小心把:

logging.Formatter返回的变量logFormatter,类型是class Formatter(object)

传递给了console初始化时候的:

formatter = logging.Formatter(

    fmt=logFormatter,

    datefmt=flask_settings.LOG_CONSOLE_DATA_FORMAT)

导致后续console的log打印日志出错。

改为正常的,传递普通的字符串:

LOG_FORMAT = "[%(asctime)s %(levelname)s %(filename)s:%(lineno)d %(funcName)s] %(message)s"

formatter = logging.Formatter(

    # fmt=logFormatter,

    fmt=LOG_FORMAT,

    datefmt=flask_settings.LOG_CONSOLE_DATA_FORMAT)

就可以正常初始化file和console的log了。

正常在console和file中都能看到自己想要的日志了。

相关配置:
