01 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(r'D:\python36\Scripts\chromedriver.exe')

# 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('http://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)

# 铺货异常
except Exception as e:
    print(e)

# 最后都会把驱动浏览器关闭掉
finally:
    driver.close()
