python_scrapy_log日志

执行自动化操作时，如果出错，需要通过日志功能保存错误信息，这里写下从网上找到的相关配置资料 

# 日志
to_day = datetime.datetime.now() # 每日日志分类
LOG_ENABLED = True # 启用日志，默认不启用
LOG_ENCODING = 'utf-8'
LOG_FILE = "E:SpiderFrameworklogscrapy_{}_{}_{}.log".format(to_day.year,to_day.month,to_day.day)
LOG_LEVEL = 'WARNING' # 级别
LOG_STDOUT = True # 输出重定向至log日志，比如print
'''
严重程度由低到高排序：DEBUG < INFO < WARNING < ERROR < CRITICAL
