实训day05 selenium基本使用

from selenium import webdriver
#导入键盘Keys
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.Chrome()
 #检测代码块
try:
    #隐式等待，等待标签加载
    driver.implicitly_wait(10)
    #往京东主页发送请求
    driver.get('https://www.jd.com/')
    #通过id查找input输入框
    input_tag = driver.find_element_by_id('key')
    #send_keys为当前标签传值
    input_tag.send_keys('中华字典')
    #按键盘的回车键
    input_tag.send_keys(Keys.ENTER)
    time.sleep(10)
#捕获异常
except Exception as e:
    print(e)
#最后都会把驱动浏览器关闭掉
finally:
    driver.close()
