控制台日志按日志级别区分颜色 #80
Description
稍微修改下代码可以恢复正常显示
# server/logging.py
class ColorHandler(logging.StreamHandler):
WHITE = "0"
RED = "31"
GREEN = "32"
YELLOW = "33"
BLUE = "34"
PURPLE = "35"
def emit(self, record):
try:
msg = self.format(record)
level_color_map = {
logging.DEBUG: self.BLUE,
logging.INFO: self.GREEN,
logging.WARNING: self.YELLOW,
logging.ERROR: self.RED,
logging.CRITICAL: self.PURPLE
}
csi = f"{chr(27)}[" # 控制序列引入符
color = level_color_map.get(record.levelno, self.WHITE)
self.stream.write(f"{csi}{color}m{msg}{csi}m\n")
self.flush()
except RecursionError:
raise
except Exception:
self.handleError(record)对应修改console的输出为server.logging.ColorHandler
