django中添加日志功能

#LOGGING_DIR 日志文件存放目录
LOGGING_DIR = "logs"   # 日志存放路径
if not os.path.exists(LOGGING_DIR):
    os.mkdir(LOGGING_DIR)

import logging

LOGGING = {
    ‘version‘: 1,
    ‘disable_existing_loggers‘: False,
    ‘formatters‘: {  #格式化器
        ‘standard‘: {
            ‘format‘: ‘[%(levelname)s][%(asctime)s][%(filename)s][%(funcName)s][%(lineno)d] > %(message)s‘
        },
        ‘simple‘: {
            ‘format‘: ‘[%(levelname)s]> %(message)s‘
        },
    },
    ‘filters‘: {
        ‘require_debug_true‘: {
            ‘()‘: ‘django.utils.log.RequireDebugTrue‘,
        },
    },
    ‘handlers‘: {
        ‘console‘: {
            ‘level‘: ‘DEBUG‘,
            ‘filters‘: [‘require_debug_true‘],
            ‘class‘: ‘logging.StreamHandler‘,
            ‘formatter‘: ‘simple‘
        },
        ‘file_handler‘: {
             ‘level‘: ‘INFO‘,
             ‘class‘: ‘logging.handlers.TimedRotatingFileHandler‘,
             ‘filename‘: ‘%s/django.log‘ % LOGGING_DIR,  #具体日志文件的名字
             ‘formatter‘:‘standard‘
        }, # 用于文件输出
        ‘mail_admins‘: {
            ‘level‘: ‘ERROR‘,
            ‘class‘: ‘django.utils.log.AdminEmailHandler‘,
             ‘formatter‘:‘standard‘
        },
    },
    ‘loggers‘: {   #日志分配到哪个handlers中
        ‘mydjango‘: {
            ‘handlers‘: [‘console‘,‘file_handler‘],
            ‘level‘:‘DEBUG‘,  
            ‘propagate‘: True,
        },
        ‘django.request‘: {
            ‘handlers‘: [‘mail_admins‘],
            ‘level‘: ‘ERROR‘,
            ‘propagate‘: False,
        },
　　　　####如果要将get,post请求同样写入到日志文件中，则这个触发器的名字必须交django,然后写到handler中
    }
}

#这里我们模拟一个登陆来写

log = logging.getLogger(‘mydjango‘)  #这里的mydjango是settings中loggers里面对应的名字


class Login(View):
    def get(self,request):
        return render(request,‘login.html‘)
    def post(self,request):
        user = request.POST.get(‘username‘)
        pwd = request.POST.get(‘password‘)
        try:
            s = 1/0
        except Exception as e:
            log.error(e)
