Detailed explanation of ticket brushing function realized by python applet

Brush tickets 1 to break through the following restrictions:

1. Verification code identification

2. Discontinuous voting with 1ip

Solution

1. With tesseract tool, the link is here https://code.google.com/p/tesseract-ocr/(everyone still can't add https link)

2. Using proxies, domestic proxy servers can find http://cn-proxy.com/here

Of course, the programming language is python

The browser voting process is as follows

1. Send a request to the server, and the server returns the verification code and form

2. Fill out the form and send it to the server

You can use the firefox+httpfox plug-in to view the entire event process, as well as the POST and GET data formats in which the request was sent

Use the urllib2 library of python to implement the above process

1. Request the verification code from the server

Can be used

import urllib
urllib.urlretrieve(imgurl,imgfile)#imgurl You can find it from the page source code 

However, since the verification code will be regenerated every time the server is requested, even if the verification code of the requested channel is recognized, an error will be prompted when POST goes in. Use cookie for solution

import cookie
import urllib2
cookiejar=cookielib.MozillaCookieJar(cookieFilename)
opener=urllib2.build_opener(urllib2.HTTPCookieProcessor(cookiejar))
response=opener.open(imgurl)

If you need to use a proxy server, you can write

import cookie
import urllib2
proxy_line='127.0.0.1:8087'
cookieFilename='cookie.txt'
cookiejar=cookielib.MozillaCookieJar(cookieFilename)
opener=urllib2.build_opener(urllib2.ProxyHandler({'http':proxy_line}),urllib2.HTTPCookieProcessor(cookieFileJar))
response=opener.open(imgurl,timeout=2)# Set timeout time 

This is to access the server with cookie authentication on port 8087 of this machine, identify the verification code in the next step, and still bring cookie POST into the server.

2. Save the verification code locally

The above response returns the binary flow of verification code, and writes the file with the following code

content=response.read()
fp=file(imgfile,'wb')# Will 2 Binary picture saving 
fp.write(content)
fp.close()

3. Verification code identification

tesseract is used for verification code identification. Because tesseract does not provide python interface, external commands are called by system here

Usage is

import os
imgfile='img.jpg'
out
