'''
    什么是phantomJs:无界面的浏览器
'''
from selenium import webdriver
from time import sleep
bro = webdriver.PhantomJS(executable_path='./phantomjs-2.1.1-windows/bin/phantomjs.exe')
sleep(2)
bro.get(url='https://www.baidu.com/')
sleep(3)
text_input = bro.find_element_by_id('kw')
text_input.send_keys('周杰伦')
sleep(2)
btn = bro.find_element_by_id('su')
btn.click()
sleep(3)

#浏览器执行js代码
js = 'window.scrollTo(0,document.body.scrollHeight)'
bro.execute_script(js)
sleep(3)
#截屏
bro.save_screenshot('./ppppppp.png')
#获取当前浏览器显示的页面数据
page_text = bro.page_source #页面数据也包含动态加载出来的数据
print(page_text)

bro.quit()
