1控制浏览器窗口的大小

driver.set_window_size(480,480)
代码：

from selenium import webdriver
from time import *
driver = webdriver.Chrome()
url = "http://www.baidu.com"
driver.get(url)
print("设置浏览器的宽和高")
driver.set_window_size(480,480)
sleep(3)
print("设置窗口最大化")
driver.maximize_window()
sleep(3)
driver.quit()

2.控制浏览器后退、前进back和forward方法

from selenium import webdriver
from time import *
driver = webdriver.Chrome()

url = "http://www.baidu.com"
print('new access %s' %(url))
driver.get(url)

url2 = 'http://news.baidui.com'
print('new access %s' %(url2))
driver.get(url2)
sleep(3)
print("back to %s" %(url))
driver.back()
sleep(3)
print("forword to %s" %(url2))
driver.forward()
sleep(3)
driver.quit()

3.模拟浏览器的刷新

手动刷新（F5）页面:driver.refresh()

from selenium import webdriver

from time import *

driver = webdriver.Chrome()

url = "http://www.baidu.com"

print('new access %s' %(url))

driver.get(url)

sleep(3)

driver.refresh()

sleep(3)

driver.quit()
