Scrapy logger 在每个spider实例中提供了一个可以访问和使用的实例，方法如下：

import scrapy 

class MySpider(scrapy.Spider):

        name = 'myspider'

        start_url = ['https://www.baidu.com']

        def  parse(self,response):

                self.logger.info('Parse function called on %s',response.url)

方法二：

该记录器是使用spider的名称创建的，当然也可以应用到任意项目中

import logging

import scrapy 

logger = logging.getLogger('mycustomlogger')

#创建logger模块

class MySpider(scrapy.Spider):

        name = 'myspider'

        start_url = ['https://www.baidu.com']

#触发模块

        def  parse(self,response):

        logger.info('Parse function called on %s',response.url)

只需使用logging.getLogger函数获取其名称即可使用其记录器：

import logging

logger = logging.getLogger('mycustomlogger')

logger.warning('This  is a warning')

so anyway:我们也可以使用__name__变量填充当前模块的路径，确保正在处理的任何模块设置自定义记录器：

import logging

logger = logging.getLogger(__name__)

logger.warning('This  is a warning')

在scrapy项目的settings 文件中配置

LOG_ENABLED = True #是否启动日志记录，默认True

LOG_ENCODING = 'UTF-8'

LOG_FILE = 'TEST1.LOG'#日志输出文件，如果为NONE，就打印到控制台

LOG_LEVEL = 'INFO'#日志级别，默认debug
LOG_FORMAT #日志格式
LOG_DATEFORMAT#日志日期格式
LOG_STDOUT #日志标准输出，默认False，如果True所有标准输出都将写入日志中，比如代码中的print输出也会被写入到文件
LOG_SHORT_NAMES#短日志名，默认为false，如果为True将不输出组件名

日志如下
