刮擦后发送电子邮件 [英] Sending e-mail after scrape in scrapy

问题描述

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')))

在上面的蜘蛛代码中，它将显示蜘蛛的开始时间和结束时间，但是现在蜘蛛完成之后，我想收到来自scrapy的抓取已完成邮件。是否有可能做到这一点。如果可能的话，我们可以使用spider_closed方法编写该代码，任何人都可以分享一些示例代码以了解如何执行此操作。

In the above spider code , it will display the starting time and ending time of the spider, but now after the completion of the spider, i want to receive a mail that "Scraping has been completed" from scrapy. Is it possible to do this. If possible can we write that code in spider_closed method, can anyone please share some example code on how to do this.

推荐答案

您是否研究过文档：

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=["[e-mail]"], subject="Some subject", body="Some body", cc=["[e-mail]"])

您还可以自行实现一些自定义功能。例如，如果您要使用gmail：

Also you could implement something custom on your own. For example if you want to use gmail:

def send_mail(self, message, title):
    print "Sending mail..........."
    import smtplib
    from email.MIMEMultipart import MIMEMultipart
    from email.MIMEText import MIMEText
    gmailUser = '[e-mail]'
    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"

，然后像这样称呼它：

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