Python implements a method of replacing an absolute URL with a relative URL

This example describes a Python implementation method that replaces an absolute URL with a relative URL. Share to everyone for your reference. The specific analysis is as follows:

First, the question:

Company a project needs to upload pictures, the first colleague will upload pictures after the combination of the current host to spell an absolute URL (http://192.168.1.1:888/m/getimg?filename=xxx.jpg) because at the same time to provide the interface to the mobile phone terminal, In the mobile phone terminal will cause some bugs, change the code after the request to replace the previous URI to a relative URL (/m/getimg?filename=xxx.jpg), because the image is embedded in the contents of the IMG tag with a tag to display a large image, So you need to read the database and replace the content

Second, the solution:

#!/usr/bin/env python#-*-coding:utf-8-*-### author:cold night# email  : wh_linux@126.com#import pymongoimport refr Om stringio Import stringioconn = Pymongo. Connection () db = Conn.testdef 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 ()
