loguru基本使用方法请参考：https://blog.csdn.net/weixin_35757704/article/details/123047652

将日志序列化的方法是：

from loguru import loggerlogger.add("my_log_debug.log", level="DEBUG",format="{time:YYYY-MM-DD HH:mm:ss.SSS} {level} {message}", enqueue=True, serialize=True)

即可将所有使用logger写入的日志转变为json格式，方便进行解析

完整示例

from loguru import logger
import jsondef generate_log():logger.add("my_log_debug.log", level="DEBUG",format="{time:YYYY-MM-DD HH:mm:ss.SSS} {level} {message}", enqueue=True, serialize=True)logger.debug("debug_a")logger.debug("debug_b")logger.info("info_a")logger.success("success_a")logger.error("error_a")def analyze_file(file_name):with open(file_name, 'r', encoding="utf-8") as fp:for line in fp:json_info = json.loads(line)print({"TIME": json_info['record']["time"]['repr'],"MESSAGE": json_info['record']['message'],})if __name__ == '__main__':generate_log()analyze_file("my_log_debug.log")

结果：
