selenium登录百度

一、概述

由于百度页面经常更新，因此页面元素，比如class和id会做更新。因此网上大多数文章，直接拿来用，是无法实现登录的。

二、完整代码

# ！/usr/bin/python3
# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time
import random

USERNAME = 'xiao' # 输入账号
PASSWORD = '123456' # 输入密码

# 随机时间，防止过快被检测
seconds = random.randint(2, 5)
chrome_driver = r"E:virtualenvdjangochromedriver.exe"
driver = webdriver.Chrome(executable_path=chrome_driver)
driver.maximize_window()
wait = WebDriverWait(driver, 10)
driver.get('https://www.baidu.com')

# 打开登录界面
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#u1 > a.lb'))).click()
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#TANGRAM__PSP_11__footerULoginBtn'))).click()
time.sleep(seconds)
# 输入账号密码
wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '#TANGRAM__PSP_11__userName'))).send_keys(USERNAME)
time.sleep(seconds)
wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '#TANGRAM__PSP_11__password'))).send_keys(PASSWORD)
time.sleep(seconds)
# # 勾选下次自动登录
# wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '#TANGRAM__PSP_11__memberPassLabel'))).click()
# time.sleep(seconds)
# 点击登录按钮
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#TANGRAM__PSP_11__submit'))).click()

注意：请根据实际情况，修改账号和密码，页面元素的id。

最重要就是chrome_driver，必须要和你的谷歌浏览器版本一致
