selenium+python配置chrome浏览器的选项的实现

# .\Lib\site-packages\selenium\webdriver\chrome\options.py
class Options(object):

  def __init__(self):
    # 设置 chrome 二进制文件位置
    self._binary_location = ''
    # 添加启动参数
    self._arguments = []
    # 添加扩展应用
    self._extension_files = []
    self._extensions = []
    # 添加实验性质的设置参数
    self._experimental_options = {}
    # 设置调试器地址
    self._debugger_address = None

# 设置默认编码为 utf-8，也就是中文

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('lang=zh_CN.UTF-8')
driver = webdriver.Chrome(chrome_options = options)

# 设置默认编码为 utf-8，也就是中文

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('lang=zh_CN.UTF-8')
driver = webdriver.Chrome(chrome_options = options)

# 通过设置user-agent，用来模拟移动设备
# 比如模拟 android QQ浏览器
options.add_argument('user-agent="MQQBrowser/26 Mozilla/5.0 (Linux; U; Android 2.3.7; zh-cn; MB200 Build/GRJ22; CyanogenMod-7) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1"')

# 模拟iPhone 6
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"')

# 禁止图片的加载
from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
prefs = {"profile.managed_default_content_settings.images": 2}
chrome_options.add_experimental_option("prefs", prefs)

# 启动浏览器，并设置好wait
browser = webdriver.Chrome(chrome_options=chrome_options)
browser.set_window_size(configure.windowHeight, configure.windowWidth)  # 根据桌面分辨率来定，主要是为了抓到验证码的截屏
wait = WebDriverWait(browser, timeout = configure.timeoutMain)

from selenium import webdriver
# 静态IP：102.23.1.105：2005
# 阿布云动态IP：http://D37EPSERV96VT4W2:CERU56DAEB345HU90@proxy.abuyun.com:9020

# 添加xpath helper应用

from selenium import webdriver
chrome_options = webdriver.ChromeOptions()

# 设置好应用扩展
extension_path = 'D:/extension/XPath-Helper_v2.0.2.crx'
chrome_options.add_extension(extension_path)

# 启动浏览器，并设置好wait
browser = webdriver.Chrome(chrome_options=chrome_options)

# 第一种方式
# chrome浏览器的扩展程序都在：C:\Users\Administrator\AppData\Local\Google\Chrome\User Data\Profile 2\Extensions\下
chrome_options.add_argument("user-data-dir=C:/Users/Administrator/AppData/Local/Google/Chrome/User Data")

# 加载所有Chrome配置， 用Chrome地址栏输入chrome://version/，查看自己的“个人资料路径”，然后在浏览器启动时，调用这个配置文件，代码如下：
from selenium import webdriver
option = webdriver.ChromeOptions()
option.add_argument('--user-data-dir=C:\Users\Administrator\AppData\Local\Google\Chrome\User Data') #设置成用户自己的数据目录
driver = webdriver.Chrome(chrome_options=option)

# 出现错误结果
第一，所有浏览器窗口，包括自己打开的都会被控制住。
第二，其他动作不起作用，而且会crash。
