Question

我正在尝试单击按钮后获得网站提供的值。

这是网站：https://www.4devs.com.br/gerador_de_cpf

您会看到有一个名为“ Gerar CPF”的按钮，该按钮提供了单击后显示的数字。

我当前的脚本打开浏览器并获取值，但是我是在单击之前从页面获取值的，所以该值为空。我想知道单击按钮后是否可以获得该值。

from selenium import webdriver
from bs4 import BeautifulSoup
from requests import get

url = "https://www.4devs.com.br/gerador_de_cpf"

def open_browser():
    driver = webdriver.Chrome("/home/felipe/Downloads/chromedriver")
    driver.get(url)
    driver.find_element_by_id('bt_gerar_cpf').click()

def get_cpf():
    response = get(url)

    page_with_cpf = BeautifulSoup(response.text, 'html.parser')

    cpf = page_with_cpf.find("div", {"id": "texto_cpf"}).text

    print("The value is: " + cpf)


open_browser()
get_cpf()

Answer 1

open_browser和get_cpf绝对不相关...

实际上，您根本不需要get_cpf。单击按钮后只需等待文本：

from selenium.webdriver.support.ui import WebDriverWait as wait

def open_browser():
    driver = webdriver.Chrome("/home/felipe/Downloads/chromedriver")
    driver.get(url)
    driver.find_element_by_id('bt_gerar_cpf').click()
    text_field = driver.find_element_by_id('texto_cpf')
    text = wait(driver, 10).until(lambda driver: not text_field.text == 'Gerando...' and text_field.text)
    return text

print(open_browser())

更新

与请求相同：

import requests

url = 'https://www.4devs.com.br/ferramentas_online.php'
data = {'acao': 'gerar_cpf', 'pontuacao': 'S'}
response = requests.post(url, data=data)
print(response.text)

Answer 2

您可以使用While循环直到文本更改吗？

from selenium import webdriver

url = "https://www.4devs.com.br/gerador_de_cpf"

def get_value():
    driver = webdriver.Chrome()
    driver.get(url)
    driver.find_element_by_id('bt_gerar_cpf').click()
    while driver.find_element_by_id('texto_cpf').text == 'Gerando...':
        continue
    val = driver.find_element_by_id('texto_cpf').text
    driver.quit()
    return val

print(get_value())

Answer 3

您不需要使用请求和BeautifulSoup。

from selenium import webdriver
from time import sleep

url = "https://www.4devs.com.br/gerador_de_cpf"

def get_cpf():
    driver = webdriver.Chrome("/home/felipe/Downloads/chromedriver")
    driver.get(url)
    driver.find_element_by_id('bt_gerar_cpf').click()
    sleep(10)
    text=driver.find_element_by_id('texto_cpf').text
    print(text)
get_cpf()

单击按钮后使用BeautifulSoup Python获得价值
