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()
答案 0 :(得分:5)
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)

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())

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()
