1. 第一种方法

第一种方法是通过device name来确定我们要模拟的手机样式，示例代码如下：

# -*- coding: utf-8 -*-

from selenium import webdriver

from time import sleep

mobileEmulation = {'deviceName': 'Apple iPhone 4'}

options = webdriver.ChromeOptions()

options.add_experimental_option('mobileEmulation', mobileEmulation)

driver = webdriver.Chrome(executable_path='chromedriver.exe', chrome_options=options)

driver.get('http://m.baidu.com')

sleep(3)

driver.close()

如上，可直接指定deviceName，具体deviceName应该怎么写，可以调出开发者工具，看看Device下拉框中的选项内容。

2. 第二种方法

或者你可以直接指定分辨率以及UA标识，如下：

# -*- coding: utf-8 -*-

from selenium import webdriver

from time import sleep

WIDTH = 320

HEIGHT = 640

PIXEL_RATIO = 3.0

UA = 'Mozilla/5.0 (Linux; Android 4.1.1; GT-N7100 Build/JRO03C) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/35.0.1916.138 Mobile Safari/537.36 T7/6.3'

mobileEmulation = {"deviceMetrics": {"width": WIDTH, "height": HEIGHT, "pixelRatio": PIXEL_RATIO}, "userAgent": UA}

options = webdriver.ChromeOptions()

options.add_experimental_option('mobileEmulation', mobileEmulation)

driver = webdriver.Chrome(executable_path='chromedriver.exe', chrome_options=options)

driver.get('http://m.baidu.com')

sleep(3)

driver.close()

上面这种方法直接指定了宽度、高度、分辨率以及ua标识，全部可以自定义。

你也可以配合 driver.set_window_size(width,height) 来将浏览器窗口设置为相同大小，这样看起来更舒服一些。

现在，你可以用chrome来模拟手机浏览器测试手机网页了。用touch_actions来模拟手指操作吧！
