记录从logs.txt到exceptions.txt的多行错误

问：

'我目前正在尝试使用 VSCode 中的 python 仅记录logs.txt文件到exceptions.txt文件的单行和多行错误。我正在编写解析器代码的所有三个文件（即 logs.txt、exceptions.txt 和 log_parser.py）都存在于我在 VS Code 上打开的同一文件夹中。

我在 logs.txt 文件上有各种多行异常，还有一些单行异常，我需要以一种方式登录exceptions.txt文件—— 错误编号。例外： 异常类型：__ 时间戳：__ 详：__

我也不希望exceptions.txt文件中有任何重复。

我正在使用 loguru 做同样的事情。 现在，我可以成功地将所有单行错误记录在exceptions.txt文件中，但无法正确执行多行错误，因为它们也被记录为单行错误。

这是我的代码：'

from loguru import logger
import re

logger.add("exceptions.txt", format="{message}", level="ERROR")

def log_exceptions():
    with open("logs.txt", "r", encoding="utf-8") as file:
        logs = file.read()

    pattern = r"\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d{3}.*? E (.*?): (.*?)(?=\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d{3}.*? E .*?:|$)"
    errors = re.finditer(pattern, logs, flags=re.DOTALL)

    error_set = set()
    error_number = 1
    multiline_exception = False
    multiline_exception_type = ""
    multiline_exception_details = ""

    for match in errors:
        exception_line = match.group(1).strip()
        exception_details = match.group(2).strip()

        if multiline_exception:
            if exception_line.startswith("java.lang.") or exception_line.startswith("at "):
                multiline_exception_details += f"\n{exception_line}"
            else:
                logger.error(f"{error_number}. {multiline_exception_type}")
                logger.error(f"Exception Type: {multiline_exception_type}")
                logger.error(f"Details:\n{multiline_exception_details}")
                error_set.add(multiline_exception_details)
                error_number += 1
                multiline_exception = False

        exception_type_match = re.search(r"java\.lang\.(.*?)\b", exception_line)
        if exception_type_match:
            exception_type = exception_type_match.group(1)
            multiline_exception = True
            multiline_exception_type = exception_type
            multiline_exception_details = exception_details
        else:
            exception_type = exception_line.split(".")[-1]

            if exception_details not in error_set:
                logger.error(f"{error_number}. {exception_type}")
                logger.error(f"Exception Type: {exception_type}")
                logger.error(f"Details:\n{exception_details}")
                error_set.add(exception_details)
                error_number += 1

    # Additional handling for the last multi-line exception in the logs
    if multiline_exception:
        logger.error(f"{error_number}. {multiline_exception_type}")
        logger.error(f"Exception Type: {multiline_exception_type}")
        logger.error(f"Details:\n{multiline_exception_details}")

# Usage
log_exceptions()

“看看这个，请试着帮助我。谢谢！

我期待这样的多行异常： `
