selenium启动chrome模拟器模拟手机

一、如果chrome选项里边有这个模拟设备（比如iPhone 6 Plus）：

1、先启动Selenium Grid， 比如命令：java -jar selenium-server-standalone-XXX.jar。

2、代码如下：

#coding=utf-8
from selenium import webdriver

mobile_emulation = { "deviceName": "iPhone 6 Plus" }
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',
                          desired_capabilities = chrome_options.to_capabilities())

二、如果chrome选项里边没有预置这个模拟设备，也可以自己配置，代码如下：

#coding=utf-8
from selenium import webdriver

mobile_emulation = {
    "deviceMetrics": { "width": 414, "height": 736, "pixelRatio": 3.0 },
    "userAgent": "Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1" }
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
driver = webdriver.Chrome(chrome_options = chrome_options)

三、修改浏览器的User-Agent来伪装你的浏览器访问手机m站，代码如下：

#coding=utf-8
from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--user-agent=Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1') 
driver = webdriver.Chrome(chrome_options = chrome_options)
