Question

我有一个愚蠢的代码，带有一个称为日志记录的库。我想将调试模式的简历放在特定路径./logs/中的文件中。在代码的中间，我有要保存在.log文件中的INFO，但尚不能使用。我认为我在一个非常基本的问题上错了，但我没有看到。

# coding=utf-8
import re
import os
import csv
import datetime, timedelta
import logging
import logging.config


def configure_logging(logger):

    # Configure logger with custom formatter.
    logger.setLevel(logging.DEBUG)
    formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")

    # Create file handler which logs DEBUG messages.
    now = datetime.now().strftime('%Y%m%d-%Hh%M')
    logname = './logs/' + now + '.log'
    fh = logging.FileHandler(logname)
    fh.setLevel(logging.DEBUG)
    fh.setFormatter(formatter)

    # Create console handler with a higher log level.
    ch = logging.StreamHandler()
    ch.setLevel(logging.DEBUG)
    ch.setFormatter(formatter)

    # Add handlers to the logger
    logger.addHandler(fh)
    logger.addHandler(ch)

def between(value, a, b):
    pos_a = value.find(a)  # Find and validate before-part.
    if pos_a == -1: return ""  # Find and validate after part.
    pos_b = value.rfind(b)
    if pos_b == -1: return ""  # Return middle part.
    adjusted_pos_a = pos_a + len(a)
    if adjusted_pos_a >= pos_b: return ""
    return value[adjusted_pos_a:pos_b]

def main():
    logger = logging.getLogger('Main')
    configure_logging(logger)

    module_logger = logging.getLogger('Extract Information')

    def scan_folder():
        path = '/Users/anna/PycharmProjects/extractData/DiarioOficial'

        with open('All.csv', 'w') as csvFile:
            headers = ['COMPANY NAME', 'CVE']
            writer = csv.writer(csvFile, delimiter=';')
            writer.writerow(headers)
            for (path, dirnames, file_names) in os.walk(path):
                for file_name in file_names:
                    if file_name.endswith(".txt"):
                        file_path=os.path.join(path, file_name)
                        mensaje = open(file_path).read()

                        module_logger.info('File is opened correct')

                        # Company Name
                        keywords_cap = ['SpA', 'SPA', 'LIMITADA', 'LTDA', 'S.A.', 'E.I.R.L.', 'S.L.']
                        # re.escape to solve the problem with metacharacters in keyword_obj
                        keywords_cap = map(re.escape, keywords_cap)
                        # sorting the items by lengh in descending order
                        keywords_cap.sort(key=len, reverse=True)
                        obj = re.compile(r'[:,;.]\s*"?([^:,;.]*?(?<!\w)(?:{}))'.format('|'.join(keywords_cap)))
                        obj2 = obj.search(mensaje)
                        if obj2:
                            # To obtain the first match in group(1)
                            company_name = obj2.group(1)
                        else:
                            company_name = "None"

                        # CVE Number of the file
                        regex = r"\s*CVE\s+([^|]*)"
                        matches = re.search(regex, mensaje)
                        if matches:
                            company_cve = matches.group(1).strip()
                        else:

                            company_cve = "None"

                        csvData = [company_name, company_cve]
                        csvData = [str(data).replace('\n', '').replace('\r', '') for data in csvData]
                        writer = csv.writer(csvFile, delimiter=';')
                        writer.writerow(csvData)
    scan_folder()

if __name__ == '__main__':
    main()

可以看出，这是一个简单的代码，用于创建cvs，并在其中输入从.txt文件提取的数据。正则表达式已用于从文本文件中提取数据。

我调整了您的代码，使其仅专注于 logging 部分：

# coding=utf-8
import logging
from datetime import datetime  # You had a minor bug here, see https://stackoverflow.com/questions/415511/how-to-get-the-current-time-in-python


def configure_logging(logger):
    # Unchanged
    # ...

def main():
    logger = logging.getLogger('Main')
    configure_logging(logger)

    # Here, you need to use the configured logger, not another one
    logger.info("This is a test writing in log file")

if __name__ == '__main__':
    main()

请注意，在运行代码之前，您需要手动创建 logs 文件夹。运行此命令后，我在logs文件夹中有一个文件，内容如下：

2018-08-17 10:13:09,304 - Main - INFO - This is a test writing in log file
