selenium爬取页面基本使用

#encoding=utf-8
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.PhantomJS()   #获取浏览器
driver.get('http://top.zhan.com/') #打开要爬取的页面
time.sleep(3)                          #等待3s,让页面加载完全
with open('liulong.html','w') as file:     #将爬取的代码储存到本地
    file.write(driver.page_source.encode('utf-8'))
# print type(driver.page_source.encode('utf-8'))
driver.quit()                                #关闭浏览器
