1、把下面代码复制到一个.py文件中
#!/usr/bin/env python
# encoding: utf-8
import logging
# now we patch Python code to add color support to logging.StreamHandler
def add_coloring_to_emit_windows(fn):
# add methods we need to the class
def _out_handle(self):
import ctypes
return ctypes.windll.kernel32.GetStdHandle(self.STD_OUTPUT_HANDLE)
out_handle = property(_out_handle)
def _set_color(self, code):
import ctypes
# Constants from the Windows API
self.STD_OUTPUT_HANDLE = -11
hdl = ctypes.windll.kernel32.GetStdHandle(self.STD_OUTPUT_HANDLE)
ctypes.windll.kernel32.SetConsoleTextAttribute(hdl, code)
setattr(logging.StreamHandler, '_set_color', _set_color)
def new(*args):
FOREGROUND_BLUE = 0x0001 # text color contains blue.
FOREGROUND_GREEN = 0x0002 # text color contains green.
FOREGROUND_RED = 0x0004 # text color contains red.
FOREGROUND_INTENSITY = 0x0008 # text color is intensified.
FOREGROUND_WHITE = FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED
# winbase.h
STD_INPUT_HANDLE = -10
STD_OUTPUT_HANDLE = -11
STD_ERROR_HANDLE = -12
# wincon.h
FOREGROUND_BLACK = 0x0000
FOREGROUND_BLUE = 0x0001
FOREGROUND_GREEN = 0x0002
FOREGROUND_CYAN = 0x0003
FOREGROUND_RED = 0x0004
FOREGROUND_MAGENTA = 0x0005
FOREGROUND_YELLOW = 0x0006
FOREGROUND_GREY = 0x0007
FOREGROUND_INTENSITY = 0x0008 # foreground color is intensified.
BACKGROUND_BLACK = 0x0000
BACKGROUND_BLUE = 0x0010
BACKGROUND_GREEN = 0x0020
BACKGROUND_CYAN = 0x0030
BACKGROUND_RED = 0x0040
BACKGROUND_MAGENTA = 0x0050
BACKGROUND_YELLOW = 0x0060
BACKGROUND_GREY = 0x0070
BACKGROUND_INTENSITY = 0x0080 # background color is intensified.
levelno = args[1].levelno
if (levelno >= 50):
color = BACKGROUND_YELLOW | FOREGROUND_RED | FOREGROUND_INTENSITY | BACKGROUND_INTENSITY
elif (levelno >= 40):
color = FOREGROUND_RED | FOREGROUND_INTENSITY
elif (levelno >= 30):
color = FOREGROUND_YELLOW | FOREGROUND_INTENSITY
elif (levelno >= 20):
color = FOREGROUND_GREEN
elif (levelno >= 10):
color = FOREGROUND_MAGENTA
else:
color = FOREGROUND_WHITE
args[0]._set_color(color)
ret = fn(*args)
args[0]._set_color(FOREGROUND_WHITE)
# print "after"
return ret
return new
def add_coloring_to_emit_ansi(fn):
# add methods we need to the class
def new(*args):
levelno = args[1].levelno
if (levelno >= 50):
color = '\x1b[31m' # red
elif (levelno >= 40):
color = '\x1b[31m' # red
elif (levelno >= 30):
color = '\x1b[33m' # yellow
elif (levelno >= 20):
color = '\x1b[32m' # green
elif (levelno >= 10):
color = '\x1b[35m' # pink
else:
color = '\x1b[0m' # normal
try:
args[1].msg = color + args[1].msg + '\x1b[0m' # normal
except Exception as e:
pass
# print "after"
return fn(*args)
return new
import platform
if platform.system() == 'Windows':
# Windows does not support ANSI escapes and we are using API calls to set the console color
logging.StreamHandler.emit = add_coloring_to_emit_windows(logging.StreamHandler.emit)
else:
# all non-Windows platforms are supporting ANSI escapes so we use them
logging.StreamHandler.emit = add_coloring_to_emit_ansi(logging.StreamHandler.emit)
# log = logging.getLogger()
# log.addFilter(log_filter())
# //hdlr = logging.StreamHandler()
# //hdlr.setFormatter(formatter())
2、将文件放到项目的utils包中(或者项目其他路径)
3、在配置文件中导入这个py文件
比如在Django的setting.py文件中配置日志信息时,可以先导入这个文件
之后运行代码,控制台会根据日志等级显示不同的颜色
4、pycharm版本最好是17版本以上的
