使用selenium的remote WebDriver

要使用?remote WebDriver?，你先要運行?Selenium server?,用下面這個命令:

  java -jar selenium-server-standalone-2.x.x.jar

運行 Selenium server時，你可以看到類似這樣一條信息:

  15:43:07.541 INFO - RemoteWebDriver instances should connect to: http://127.0.0.1:4444/wd/hub

意思是說你可以用這個URL連接到 ?remote WebDriver?,下面是一些例子:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

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

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

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

?desired_capabilities? 是一個?dict?，如果你不使用默認的?dict?，你可以自己指定值:

driver = webdriver.Remote(
   command_executor='http://127.0.0.1:4444/wd/hub',
   desired_capabilities={'browserName': 'htmlunit',
                         'version': '2',
                        'javascriptEnabled': True})
