這篇博客對于考公人或者其他用華圖或者粉筆做題的人比較友好，通過輸入網址可以自動化獲取華圖以及粉筆練習的錯題。

粉筆網站

我們從做過的題目組中獲取錯題

打開某一次做題組，我們首先進行抓包看看數據在哪里

我們發現現在數據已經被隱藏，事實上數據在這兩個包中：

https://tiku.fenbi.com/api/xingce/questions

https://tiku.fenbi.com/api/xingce/solutions

一個為題目的一個為解析的。此url要通過傳入一個題目組參數才能獲取到當前題目數據，而題目組參數在這個包中

以網址的倒數第二個數字串有關

url的規則為'https://tiku.fenbi.com/api/xingce/exercises/'+str(id_)+'?app=web&kav=12&version=3.0.0.0'，id_即為下劃線數字

通過請求這個包獲取到參數然后通過參數請求上面兩個包(

https://tiku.fenbi.com/api/xingce/questions

https://tiku.fenbi.com/api/xingce/solutions

不過粉筆的題目數據有些是圖片，而且圖片在題目中，選項中，這里以word文檔存儲操作docx庫有些吃力，于是我想到了直接構造HTML代碼，然后通過pdfkit轉為pdf(具體如何下載可以參考百度，要下載wkhtmltopdf.exe)即可變為錯題集在平板或者其他設備中看。

(請求時一定要攜帶完整的headers，否則很可能獲取不到數據)

具體操作看代碼解析

###此函數用于解析題目和每道題的答案

def jiexi(liebiao):

new = []

timu_last = []

for each in liebiao:

new.append(re.sub(r'flag=\\"tex\\" ','',each))

for each in new:

timu_last.append(re.sub(r'\\','',each))

return timu_last

###此函數用于解析選項

def xuanxiang(liebiao):

xuanxiang_v2 = []

xuanxiang_v3 = []

for each in liebiao:

a = re.sub('

','',each)

a = re.sub('

','',a)

xuanxiang_v2.append(a)

for each in xuanxiang_v2:

each = each+'

'

xuanxiang_v3.append(each)

return xuanxiang_v3

import requests

import re

import pdfkit

import os

url = str(input("請輸入練習的網址："))

###獲取本節練習id

id_ = re.findall(r'https://www.fenbi.com/spa/tiku.*?/xingce/xingce/(.*?)/',url,re.S)[0]

mid_url = 'https://tiku.fenbi.com/api/xingce/exercises/'+str(id_)+'?app=web&kav=12&version=3.0.0.0'

headers = {

#####完整的headers，自己添加

}

response = requests.get(url=mid_url,headers=headers)

response.encoding = 'utf-8'

page_text = response.text

###獲取題目組參數

id_list = re.findall('\"questionIds\"\:\[(.*?)\]\,',page_text,re.S)

###獲取自己的答案

your_answer = re.findall(r'"answer":{"choice":"(.*?)",',page_text,re.S)

###此練習名稱

name = re.findall(r'"name":"(.*?)",',page_text,re.S)[0]

###真正存儲數據的包

timu_url = 'https://tiku.fenbi.com/api/xingce/questions'

params = {

'ids': id_list

}

response = requests.get(url=timu_url,headers=headers,params=params)

response.encoding = 'utf-8'

page_text = response.text

###獲取正確答案

true_answer = re.findall('"correctAnswer":{"choice":"(.*?)"',page_text,re.S)

###真正存儲數據的包

solution_url = 'https://tiku.fenbi.com/api/xingce/solutions'

response = requests.get(url=solution_url,headers=headers,params=params)

response.encoding = 'utf-8'

page_text = response.text

###獲取解析

solution_list = re.findall(r'"solution":"(.*?)","userAnswer"',page_text,re.S)

solution_last = jiexi(solution_list)

cailiao = []

timu = []

###獲取單選題題目和復合題的題目

for each in response.json():

timu.append(each['content'])

try:

cailiao.append(each['material']['content'])

except:

cailiao.append('none')

###獲取選項信息

A_option = re.findall('\"options\"\:\[\"(.*?)\"\,\".*?\"\,\".*?\"\,\".*?\"\]',page_text,re.S)

B_option = re.findall('\"options\"\:\[\".*?\"\,\"(.*?)\"\,\".*?\"\,\".*?\"\]',page_text,re.S)

C_option = re.findall('\"options\"\:\[\".*?\"\,\".*?\"\,\"(.*?)\"\,\".*?\"\]',page_text,re.S)

D_option = re.findall('\"options\"\:\[\".*?\"\,\".*?\"\,\".*?\"\,\"(.*?)\"\]',page_text,re.S)

A_option = xuanxiang(A_option)

B_option = xuanxiang(B_option)

C_option = xuanxiang(C_option)

D_option = xuanxiang(D_option)

A_option = jiexi(A_option)

B_option = jiexi(B_option)

C_option = jiexi(C_option)

D_option = jiexi(D_option)

###構造HTML代碼

count = 0

all_content = "\n\n"

for each in true_answer:

if each != your_answer[count]:

###處理復合題

if cailiao[count] != 'none' and cailiao[count] not in all_content:

all_content += cailiao[count]

all_content += str(count+1)

all_content += '、'

all_content += timu[count][3:]

all_content += 'A、'

all_content += A_option[count]

all_content += 'B、'

all_content += B_option[count]

all_content += 'C、'

all_content += C_option[count]

all_content += 'D、'

all_content += D_option[count]

all_content += '
'

count += 1

count = 0

all_content += '
'

for each in true_answer:

if each != your_answer[count]:

temp = '第'+str(count+1)+'題的正確答案為'

all_content += temp

if true_answer[count]=='0':

all_content += 'A'

elif true_answer[count]=='1':

all_content += 'B'

elif true_answer[count]=='2':

all_content += 'C'

elif true_answer[count]=='3':

all_content += 'D'

all_content += solution_last[count]

all_content += '
'

count += 1

all_content += ''

path_name = name + '.html'

###保存為HTML文件

with open(path_name,'w',encoding='utf-8') as fp:

fp.write(all_content)

confg = pdfkit.configuration(wkhtmltopdf=r'wkhtmltopdf.exe保存的路徑')

pdfkit.from_url(path_name, name+'.pdf',configuration=confg)###把HTML文件轉為pdf

print('錯題PDF保存成功')

###刪除HTML文件

os.remove(path_name)

華圖網站

也是答題記錄中自己做過的題目

華圖網站稍微不一樣，他的數據直接抓包就可看到

通過請求這個包即可獲取到數據，接下來就是解析的事情了，這次我用word文檔進行存儲，如果覺得不方便也可以像上文一樣構造HTML

##導包

import requests

import lxml.etree

import re

import time

import os

from docx import Document

from docx.shared import Inches

from docx.shared import Pt

from docx.shared import Inches

from docx.oxml.ns import qn

from docx.enum.text import WD_ALIGN_PARAGRAPH

url = str(input("請輸入練習的網址："))

headers={

###完整的headers，否則獲取不到數據

}

response = requests.get(url = url,headers = headers)

response.encoding='utf-8'

reptext = response.text

tree = lxml.etree.HTML(reptext) #解析網站獲取源碼

dirName="考公圖片"

if not os.path.exists(dirName):

os.mkdir(dirName) #網站圖片保存路徑

jiexi = re.findall(r'

解析.*?。 .*? ', reptext,re.S) #獲取題目解析
