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字符串，其中包含转换为链接的电子邮件地址。

示例：

>>>s = 'blah blah blah a@at.com blah blah blah'
>>>link(s)
'blah blah blah <a href="mailto:a@at.com">a@at.com</a> blah blah blah'

Answer 1

这样的东西？

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: bob@example.com, and another: joe@example.com")

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 a@at.com blah blah blah'
>>> convert_emails(s)
'blah blah blah <a href="mailto:a@at.com">a@at.com</a> blah blah blah'
>>>

不是非常强大，但适用于非常基本的情况。

Answer 3

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