This article mainly introduces the relevant knowledge of "Python+selenium how to crack the jigsaw verification code". The editor shows you the operation process through the actual case, the operation method is simple and fast, and the practicality is strong. I hope this article "how to crack the jigsaw verification code by Python+selenium" can help you solve the problem.

Realization idea

Many websites have jigsaw verification codes.

1. First of all, it is necessary to understand the generation principle of jigsaw verification code.

two。 Make a cracking plan and consider its possibility and success rate.

3. Write a script

The puzzle verification codes of many websites are directly with the help of third-party plug-ins, that is, a kind of solution.

This kind of jigsaw verification code encountered by the author is actually a whole after a number of small fragments have been reassembled. First of all, we have to grab this small fragment image on the website and download it to the local.

Let's first sort out the general idea:

Take pictures of all the fragments-find out their order logic-find the sequence number of the small piece in which they contain the true position of the dark color-calculate the distance based on the width and the sequence number of each piece and the dark piece-move the slider to the right with selenium to this distance.

Core code

Import the necessary packages first:

#-*-coding:utf-8-*-import colorsysimport urllib,os,uuid,re,timefrom PIL import Imagefrom selenium.webdriver.common.action_chains import ActionChainsfrom selenium import webdriver

Capture it and download it locally.

Def create (locapath,fileName): filePath=locapath+'/'+fileName if not os.path.exists (filePath): file=open (filePath,'a+') file.close () return filePathdef downloadImg (): list = openBrowser () for i in range (2): fileName = str (I) +'_ test.jpg' urllib.urlretrieve (list [I], create ('/ Users/zijiawang/Downloads/') FileName)) # download to local time.sleep (3) def openBrowser (): global wzj wzj = webdriver.Firefox () wzj.get ('https://.') Image1_url= wzj.find_elements_by_class_name ('gt_cut_bg_slice') [0] .get _ attribute (' style') image1_url=image1_ url [23:-38] image2_url= wzj.find_elements_by_class_name ('gt_cut_fullbg_slice') [0] .get _ attribute (' style') image2_url=image2_ url [23:-38] return [image1_url,image2_url]

Split and get rgb color

Ef getcolor (image): list = [[XMagne y] for x in range (26) for y in range (2)] listt = [] colors = [] for i in range (len (list)): l = list [I] [0] * 12 weeks = list [I] [1] * 58 listt.append ([12*0.25+i/2*12, 58 girls 0.25 + ((item10)% 2) * 58]) listt.append ([12*0.25+i/2*12) 58% 0.75 + ((item10)% 2) * 58]) listt.append ([12*0.75+i/2*12, 58% 0.25 + ((item10)% 2) * 58]) listt.append ([12*0.75+i/2*12, 58% 0.75 + ((ionization 10)% 2) * 58]) for i in range (len (listt)): colors.append (imageList [I] [0], listt [I] [1]) return colors

Find out the serial numbers of different small fragments.

Def getDeferent (): deferent = [] for i in range [2]: if abs (Color1 [I] [2]-color2 [I]] > 20: print ubib difference:', color1 [I] [2]-color2 [I] [2] deferent.append (I) # print ([idome abs (color1 [0]-color2 [I] [0]), abs (color1 [I] [1]-color2 [I] [1])) Abs (Color1 [I] [2]-color2 [I] [2]) return deferentdef getUPDOWN (): deferent = getDeferent () xlist = [] ylist = [] for i in deferent: if (I / 4)% 2 = = 0: xlist.append (I) else: ylist.append (I) uplist = [] downlist = [] for i in xlist: uplist.append (I / 4) for i in ylist: Downlist.append (I / 4) for i in range (len (uplist)): uplist [I] / = 2 for i in range (len (downlist)): downlist [I] / = 2 func = lambda x Y: x if y in x else x + [y] up = reduce (func, [[],] + uplist) func = lambda x, y: x if y in x else x + [y] down = reduce (func, [[],] + downlist) return up,down

If you write the arrangement method, you will use it.

Def bubble (l): for index in range (len (l)-1,0,-1): for two_index in range (index): if 1 [two _ index] > 1 [two _ index + 1]: 1 [two _ index], 1 [two _ index + 1] = 1 [two _ index + 1], 1 [two _ index] return l

Finally, analyze and assemble the source code.

Def end (): orders = getUPDOWN () orderx = orders [0] ordery = orders [1] orderx print'y Vega Magazine orderX = [145,157,277,265,169,181,253,241,97,109,301,289,73, 85,37,25,1,133,121,49,61,229,217,193,241,255,265,277,181,169,241,253,109,97,289,301,85] orderY = [157,145,265,277,181,169,241,157,253,109,97,109,301,85] 73, 25, 37, 13, 1, 121,133, 61, 49, 217,229,205,193] print upright Xpurs author orderX print upright Ypurs' OrderY for x in range (26): orderX [x]-= 1 orderX [x] / = 12 for y in range (26): orderY [y]-= 1 orderY [y] / = 12 endX = [] endY = [] for i in range (len (orderX)): for j in range (len (orderx)): if orderx [j] = orderX [I]: endX.append (I) break for i In range (len (orderY)): for j in range (len (ordery)): if ordery [j] = = orderY [I]: endY.append (I) break print 'endx:' EndX print 'endy:',endY os.remove (' / Users/zijiawang/Downloads/0_test.jpg') os.remove ('/ Users/zijiawang/Downloads/1_test.jpg') all = [] all = endX+endY # print 'all:',all # system can be tested up to 5 times func = lambda x, y: x if y in x else x + [y] all_old = reduce (func, [[],] + all) # print' all_old:' All_old all_end = bubble (all_old) print 'all_end:',all_end duandata = 1000 for i in range (1 in all_end (all_end)): if all_ end [I]-1 in all_end: pass else: duandata = all_ end [I] print u' breakpoint is:' Duandata guess = [] if duandata! = 1000: if endX! = [] and endY breakpoint = []: print u' breakpoint 1' guess = [duandata,all_end [0]] elif endX = = []: print u' breakpoint 2' guess = [duandata, endY [0]] elif endY = = []: print u' breakpoint 3' guess = [duandata EndX [0]] else: print u'no breakpoint 'guess = [all_end [0]] end_guess = [] print u' guess point:' Guess for i in guess: end_guess.append (I * 12-38) end_guess.append (I * 12-28) end_guess.append (I * 12-20) end_guess.append (I * 12-17) end_guess.append (I * 12-15) print u 'guessed displacement:', end_guess return end_guess
