贴一篇自己写的刷问卷星的脚本

• 形势与政策要做调查问卷,正好之前爬虫学了selenium,就写了个自动刷的脚本,目前仅可刷单选,但是可以单独设定每题每个选项的概率

代码实现

• 如果直接拿selenium写,问卷星就会弹验证🐎,因为问卷星有做对selenium的检测,使用下面的代码可以简单过一部分检测

options = webdriver.ChromeOptions()
options.add_argument("--disable-blink-features=AutomationControlled")
driver = webdriver.Chrome(chrome_options=options)

• 这里使用了网上的一份p_random函数,传入两个list,第一个作为被选择的元素,第二个作为每个元素被选中的概率

def p_random(arr1,arr2):
    assert len(arr1) == len(arr2), "Length does not match."
    #assert sum(arr2) == 1 , "Total rate is not 1."

    sup_list = [len(str(i).split(".")[-1]) for i in arr2]
    top = 10 ** max(sup_list)
    new_rate = [int(i*top) for i in arr2]
    rate_arr = []
    for i in range(1,len(new_rate)+1):
        rate_arr.append(sum(new_rate[:i]))
    rand = random.randint(1,top)
    data = None
    for i in range(len(rate_arr)):
        if rand <= rate_arr[i]:
            data = arr1[i]
            break
    return data

• 完整脚本如下,现在设置的11个问题(单选),可以自己按照格式添加或者删除元素,p_random第一个传入的每个选项的序号,第二个传入的每个选项的概率

from selenium import webdriver
import time
import random
def p_random(arr1,arr2):
    assert len(arr1) == len(arr2), "Length does not match."
    #assert sum(arr2) == 1 , "Total rate is not 1."

    sup_list = [len(str(i).split(".")[-1]) for i in arr2]
    top = 10 ** max(sup_list)
    new_rate = [int(i*top) for i in arr2]
    rate_arr = []
    for i in range(1,len(new_rate)+1):
        rate_arr.append(sum(new_rate[:i]))
    rand = random.randint(1,top)
    data = None
    for i in range(len(rate_arr)):
        if rand <= rate_arr[i]:
            data = arr1[i]
            break
    return data
i=1
