Python：将电子邮件地址转换为 HTML 链接

Question

我正在寻找一个独立的 python 函数，它将接收一个字符串并返回一个将电子邮件地址转换为链接的字符串。

例子：

>>>s = 'blah blah blah [email protected] blah blah blah'
>>>link(s)
'blah blah blah <a href="mailto:[email protected]">[email protected]</a> blah blah blah'

Answer 1

像这样的东西吗？

import re
import xml.sax.saxutils

def anchor_from_email_address_match(match):
    address = match.group(0)
    return "<a href=%s>%s</a>" % (
        xml.sax.saxutils.quoteattr("mailto:" + address),
        xml.sax.saxutils.escape(address))

def replace_email_addresses_with_anchors(text):
    return re.sub("\w+@(?:\w|\.)+", anchor_from_email_address_match, text)

print replace_email_addresses_with_anchors(
    "An address: [email protected], and another: [email protected]")

Answer 2

>>> def convert_emails(s):
...     words =  [ word if '@' not in word else '<a href="mailto:{0}">{0}</a>'.format(word) for word in s.split(" ") ]
...     return " ".join(words)
... 
>>> s = 'blah blah blah [email protected] blah blah blah'
>>> convert_emails(s)
'blah blah blah <a href="mailto:[email protected]">[email protected]</a> blah blah blah'
>>> 

不是超级强大，但适用于非常基本的情况。

def link(s):
    return '<a href="mailto:{0}">{0}</a>'.format(s)
