本文实例讲述了Python实现将绝对URL替换成相对URL的方法。分享给大家供大家参考。具体分析如下：
一、问题：
公司一个项目需要上传图片,一开始同事将图片上传后结合当前主机拼成了一个绝对的URL(http://192.168.1.1:888/m/getimg"htmlcode">
#!/usr/bin/env python
#-*- coding:utf-8 -*-

import pymongo
import re
from StringIO import StringIO
conn = pymongo.Connection()
db = conn.test
def replace_url():
regex = re.compile(r'([href¦src])=["¦\']http://.*"¦\']')
results = db['test'].find()
db_coll = db['test']
def replace(r):
content = r.get('content')
if not content: return
content = StringIO(content)
content.seek(0)
result = StringIO()
for line in content.readlines():
t = regex.sub(r'\1="\2"', line)
result.write(t)
result.seek(0)
content = result.read()
if content:
r['content'] = content
_id = r.get('_id')
db_coll.update({'_id':_id}, r)
results = [replace(i) for i in results]
if __name__=="__main__":replace_url()
希望本文所述对大家的Python程序设计有所帮助。
