使用BeautifulSoup Python点击按钮后获取价值

Question

我试图通过点击按钮获得网站给出的值.

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

您可以看到有一个名为"Gerar CPF"的按钮,此按钮提供单击后显示的数字.

我当前的脚本打开浏览器并获取值,但是我在点击之前从页面获取值,因此值为空.我想知道点击按钮后是否可以获取值.

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

您不需要使用 requests 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()

Answer 2

open_browser和get_cpf绝对没有关系......

其实你根本不需要get_cpf.单击按钮后等待文本:

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

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)
