使用python单击按钮后获取值

Question

我试图在单击按钮后获取网站给出的值。

这里是网站：CPF generator website

可以看到有一个按钮叫做“Gerar CPF”，这个按钮提供了一个点击后出现的数字。

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，所以该值为空。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.net.br/gerador-cpf"

def open_browser():
    driver = webdriver.Chrome("/home/willi/Documents/chromedriver")
    driver.get(url)
    driver.find_element_by_class('btn m-1 btn-primary btn-sm').click()

def get_cpf():
    response = get(url)

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

    cpf = page_with_cpf.find("input", {"id": "__BVID__61"}).text

    print("The value is: " + cpf)


open_browser()
get_cpf()

Answer 1

您可以简单地添加一个while 循环，以便在您希望的时间更新该值。例如：

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

url = "https://www.4devs.net.br/gerador-cpf"

def open_browser():
  driver = webdriver.Chrome("/home/willi/Documents/chromedriver")
  driver.get(url)
  driver.find_element_by_class('btn m-1 btn-primary btn-sm').click()

def get_cpf():
  response = get(url)

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

  cpf = page_with_cpf.find("input", {"id": "__BVID__61"}).text

  print("The value is: " + cpf)

while True:
   open_browser()
   get_cpf()
   time.sleep(your_time_in_s)

以下代码使用 Ruggero 的部分解决方案和 pyperclip 工作：

import time
import pyperclip
from selenium import webdriver
from selenium.webdriver.common.by import By
from bs4 import BeautifulSoup
from requests import get
import chromedriver_binary  # Adds chromedriver binary to path

url = "https://www.4devs.net.br/gerador-cpf"
your_time_in_s=2

def open_browser():
    driver = webdriver.Chrome()
    driver.get(url)
    driver.find_element(By.XPATH, '//*[@id="app"]/div/div[2]/div/div/div[3]/div/div[3]/div[1]/div/button[2]').click()
    time.sleep(your_time_in_s)
    driver.find_element(By.XPATH, '//*[@id="__BVID__60"]/div/div/div/button').click()
    print("The value is: " + pyperclip.paste())

while True:
    open_browser()
