在scrapy中抓取后发送电子邮件

pipeline.py代码

class Examplepipeline(object):

    def __init__(self):
        dispatcher.connect(self.spider_opened, signal=signals.spider_opened)
        dispatcher.connect(self.spider_closed, signal=signals.spider_closed)

    def spider_opened(self, spider):
        log.msg("opened spider  %s at time %s" % (spider.name,datetime.now().strftime('%H-%M-%S')))

    def process_item(self, item, spider):
            log.msg("Processsing item " + item['title'], level=log.DEBUG)


    def spider_closed(self, spider):
        log.msg("closed spider %s at %s" % (spider.name,datetime.now().strftime('%H-%M-%S')))

在上面的spider代码中，它会显示spider的开始时间和结束时间，但是现在spider完成后，我想收到来自scrapy的“抓取已完成”的邮件。是否有可能做到这一点。如果可能的话，我们可以在Spider_Closed方法中编写该代码，任何人都可以分享一些关于如何执行此操作的示例代码。

您是否查看过文档：

http://doc.scrapy.org/en/latest/topics/email.html

文档中的基本用法

from scrapy.mail import MailSender

mailer = MailSender()
mailer.send(to=["[email protected]"], subject="Some subject", body="Some body", cc=["[email protected]"])

您也可以自己实现一些自定义的东西。例如，如果您想使用 Gmail：

def send_mail(self, message, title):
    print "Sending mail..........."
    import smtplib
    from email.MIMEMultipart import MIMEMultipart
    from email.MIMEText import MIMEText
    gmailUser = '[email protected]'
    gmailPassword = 'password'
    recipient = 'mail_to_send_to'

    msg = MIMEMultipart()
    msg['From'] = gmailUser
    msg['To'] = recipient
    msg['Subject'] = title
    msg.attach(MIMEText(message))

    mailServer = smtplib.SMTP('smtp.gmail.com', 587)
    mailServer.ehlo()
    mailServer.starttls()
    mailServer.ehlo()
    mailServer.login(gmailUser, gmailPassword)
    mailServer.sendmail(gmailUser, recipient, msg.as_string())
    mailServer.close()
    print "Mail sent"

并像这样称呼它：

send_mail("some message", "Scraper Report")
