scrapy发送邮件

scrapy发送邮件

1. 首先在settings同级的目录下创建extendions(扩展)文件夹，

   代码如下：

   import logging
   
   from scrapy import signals
   
   from scrapy.exceptions import NotConfigured
   
   from scrapy.mail import MailSender
   
   logger = logging.getLogger(__name__)
   
   class SendEmail(object):
   
       def __init__(self,sender,crawler):
   
           self.sender = sender
   
           crawler.signals.connect(self.spider_idle, signal=signals.spider_idle)
   
           crawler.signals.connect(self.spider_closed, signal=signals.spider_closed)
   
       @classmethod
   
       def from_crawler(cls,crawler):
   
           if not crawler.settings.getbool('MYEXT_ENABLED'):
   
               raise NotConfigured
   
           mail_host = crawler.settings.get('MAIL_HOST') # 发送邮件的服务器
   
           mail_port = crawler.settings.get('MAIL_PORT') # 邮件发送者
   
           mail_user = crawler.settings.get('MAIL_USER') # 邮件发送者
   
           mail_pass = crawler.settings.get('MAIL_PASS') # 发送邮箱的密码不是你注册时的密码，而是授权码！！！切记！
   
           sender = MailSender(mail_host,mail_user,mail_user,mail_pass,mail_port) #由于这里邮件的发送者和邮件账户是同一个就都写了mail_user了
   
           h = cls(sender,crawler)
   
           return h
   
       def spider_idle(self,spider):
   
           logger.info('idle spider %s' % spider.name)
   
       def spider_closed(self, spider):
   
           logger.info("closed spider %s", spider.name)
   
           body = 'spider[%s] is closed' %spider.name
   
           subject = '[%s] good!!!' %spider.name
   
           # self.sender.send(to={'[email protected]'}, subject=subject, body=body)
   
           return self.sender.send(to={'[email protected]'}, subject=subject, body=body)
   
   

2. 在扩展中写好代码后，需要在settings中启用

EXTENSIONS = {

    # 'scrapy.extensions.telnet.TelnetConsole': 300,

    'bukalapak.extendions.sendmail.SendEmail': 300,

}

MYEXT_ENABLED = True
