如何抓取一个使用Python (BeautifulSoap，Requests)登录的BankID网站？

我想用BankID登录，然后用python创建一个网站。如何登录到使用BankID登录的网站？

常规方法不起作用：

from bs4 import BeautifulSoup

import requests

source = requests.get('https://example.com').text

soup = BeautifulSoup(source, 'lxml')

print(soup)

最好的方法是使用selenium。下面是使用selenium的方法：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

driver = webdriver.Chrome() #Opens the chromedriver. If u don't have a chromedriver, u can download it from https://chromedriver.chromium.org/downloads 

driver.get('Url of the banking website') #Opens the specified url

bank_id = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, 'Textbox xpath'))) #Finds the bank_id textbox 

bank_id.click() #Clicks it

bank_id.send_keys('Your username') #Enters ur username in the textbox
 
pswrd = driver.find_element_by_xpath('Xpath of textbox') #Does the same for the password.

pswrd.click()

pswrd.send_keys('Your password')

login_btn = driver.find_element_by_xpath('Xpath of submit button') #Finds the login button

login_btn.click() #Clicks the login button

就这样!您已登录网站！希望这能对你有所帮助！
