Python:尝试通过电子邮件发送 href

Question

下面的代码从 ESPN/college-football 中提取头条新闻。我可以捕获文章的标题和链接。我可以打印这两份文件，但我也想通过电子邮件发送它们。我可以获取电子邮件的标题，但不能获取 href 属性。知道发生了什么吗？

from urllib import urlopen
from BeautifulSoup import BeautifulSoup
import smtplib

# Copy all of the content from the provided web page
webpage = urlopen('http://espn.go.com/college-football').read()
soup = BeautifulSoup(webpage)    

# to get the contents of <ul> tags w/ attribute class="headlines":
for i in soup.findAll('ul', {'class': 'headlines'}):
    for tag in i.findAll('li'):
        for a in tag.findAll({'a' : True, 'title' : False}):            
            print a.text
            print a['href']                                
            print "\n"

            url = str(a.get('href'))
            fromaddr = 'FROM@from.com'
            toaddrs  = 'TO@to.com'            


            # Credentials (if needed)
            username = 'username'
            password = 'password'

            # The actual mail send
            server = smtplib.SMTP('smtp.gmail.com', 587)
            server.set_debuglevel(1)
            server.ehlo()
            server.starttls()
            server.login(username,password)
            server.sendmail(fromaddr, toaddrs, url)
            server.quit()

Eclipse 中的控制台显示:

但它从未在电子邮件中出现。

Answer 1

尝试 email 包来格式化电子邮件:

# -*- coding: utf-8 -*-
from email.header    import Header
from email.mime.text import MIMEText

msg = MIMEText('put message body here…', 'plain', 'utf-8')
msg['Subject'] = Header('here goes subject…', 'utf-8')
msg['From'] = 'from@gmail.com'
msg['To'] = 'to@example.com'
print(msg.as_string())

输出:

Content-Type: text/plain; charset="utf-8"MIME-Version: 1.0Content-Transfer-Encoding: base64Subject: =?utf-8?q?here_goes_subject=E2=80=A6?=From: from@gmail.comTo: to@example.comcHV0IG1lc3NhZ2UgYm9keSBoZXJl4oCm

To send it via gmail:

from smtplib import SMTP_SSL

s = SMTP_SSL('smtp.gmail.com')
s.set_debuglevel(1)
try:
    s.login(login, password)
    s.sendmail(msg['From'], msg['To'], msg.as_string())
finally:
    s.quit()
