from selenium import webdriver

mobile_emulation = { "deviceName": "Nexus 5" }

chrome_options = webdriver.ChromeOptions()

chrome_options.add_experimental_option("mobileEmulation", mobile_emulation) # 这里看清楚了，不是add_argument

driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',desired_capabilities = chrome_options.to_capabilities())

#====

from selenium import webdriver

from selenium.webdriver.chrome.options import Options

mobile_emulation = {

   "deviceMetrics": { "width": 360, "height": 640, "pixelRatio": 3.0 },

   "userAgent": "Mozilla/5.0 (Linux; Android 4.2.1; en-us; Nexus 5 Build/JOP40D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19" }

chrome_options = Options()

chrome_options.add_experimental_option("mobileEmulation", mobile_emulation) # 这里看清楚了，不是add_argument

driver = webdriver.Chrome(chrome_options = chrome_options) # 这里的chrome_options 建议都使用 desired_capabilities ，应为在Grid分布式中比较方便

2.取消显示 收到自动化软件的控制 / 静默方式运行

from selenium import webdriver

# 加启动配置

option = webdriver.ChromeOptions()

option.add_argument('disable-infobars')

#return webdriver.Chrome(chrome_options = option,desired_capabilities = None)

# 打开chrome浏览器

driver = webdriver.Chrome(chrome_options=option)

driver.get("https://www.baidu.com") 

from selenium import webdriver

# 加启动配置

option = webdriver.ChromeOptions()

option.add_argument('headless')

# 打开chrome浏览器

driver = webdriver.Chrome(chrome_options=option)

driver.get("https://www.baidu.com")
