Python+selenium破解拼图验证码的脚本

第Python+selenium破解拼图验证码的脚本目录实现思路核心代码

实现思路

很多网站都有拼图验证码

1.首先要了解拼图验证码的生成原理

2.制定破解计划，考虑其可能性和成功率。

3.编写脚本

很多网站的拼图验证码都是直接借助第三方插件，也就是一类一种解法。

笔者遇到的这种拼图验证码实际上是多个小碎片经过重新组合成的一张整体，首先要在网站上抓取这种小碎片图片并下载到本地

我们先捋一捋大体思路：

获取所有碎片图片----找出他们的排列顺序逻辑-----找出他们中含有颜色深的真正位置的那个小碎块的序号-----根据每块碎片的宽度和上下和这个深色小块的序号算出距离----用selenium向右移动滑块到这个距离

核心代码

先导入必要的包：

#-*-coding:utf-8-*-

importcolorsys

importurllib,os,uuid,re,time

fromPILimportImage

frommon.action_chainsimportActionChains

fromseleniumimportwebdriver

抓到并下载到本地

defcreate(locapath,fileName):

filePath=locapath+'/'+fileName

ifnotos.path.exists(filePath):

file=open(filePath,'a+')

file.close()

returnfilePath

defdownloadImg():

list=openBrowser()

foriinrange(2):

fileName=str(i)+'_test.jpg'

urllib.urlretrieve(list[i],create('/Users/zijiawang/Downloads/',fileName))#下载到本地

time.sleep(3)

defopenBrowser():

globalwzj

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]

分割并获取rgb颜色

efgetcolor(image):

list=[[x,y]forxinrange(26)foryinrange(2)]

listt=[]

colors=[]

foriinrange(len(list)):

l=list[i][0]*12+12

w=list[i][1]*58+58

listt.append([12*0.25+i/2*12,58*0.25+((i+10)%2)*58])

listt.append([12*0.25+i/2*12,58*0.75+((i+10)%2)*58])

listt.append([12*0.75+i/2*12,58*0.25+((i+10)%2)*58])

listt.append([12*0.75+i/2*12,58*0.75+((i+10)%2)*58])

foriinrange(len(listt)):

colors.append(image[listt[i][0],listt[i][1]])

returncolors

找出不同的小碎片序号

defgetDeferent():

deferent=[]

foriinrange(208):

ifabs(color1[i][2]-color2[i][2])20:

printu'B差值:',color1[i][2]-color2[i][2]

deferent.append(i)

#print([i,abs(color1[i][0]-color2[i][0]),abs(color1[i][1]-color2[i][1]),abs(color1[i][2]-color2[i][2])])

returndeferent

defgetUPDOWN():

deferent=getDeferent()

xlist=[]

ylist=[]

foriindeferent:

if(i/4)%2==0:

xlist.append(i)

else:

ylist.append(i)

uplist=[]

downlist=[]

foriinxlist:

uplist.append(i/4)

foriinylist:

downlist.append(i/4)

foriinrange(len(uplist)):

uplist[i]/=2

foriinrange(len(downlist)):

downlist[i]/=2

func=lambdax,y:xifyinxelsex+[y]

up=reduce(func,[[],]+uplist)

func=lambdax,y:xifyinxelsex+[y]

down=reduce(func,[[],]+downlist)

returnup,down

编写好排列方法，会用的

defbubble(l):

forindexinrange(len(l)-1,0,-1):

fortwo_indexinrange(index):

ifl[two_index]l[two_index+1]:

l[two_index],l[two_index+1]=l[two_index+1],l[two_index]

returnl

最后的进行解析，拼装源码
