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?filename=xxx.jpg由于同时给手机终端提供接口,在手机终端会引起一些bug,改完代码后要求将以前的uri替换成相对的URL(/m/getimg?filename=xxx.jpg),由于图片是用img标签嵌入到内容同时用a标签括起显示大图的,所以需要读取数据库并对内容进行替换,

脚本内容如下:

#!/usr/bin/env python #-*- coding:utf-8 -*- # # # author : cold night # email : wh_linux@126.com # import pymongo import re from StringIO import StringIO conn = pymongo.Connection() db = conn.test def replace_url(): regex = re.compile(r'([href|src])=["|']http://.*?(/m/getimg"|']') 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()
