我可以重新附加到selenium会话，但不能阻止它启动另一个浏览器？

Question

这是我的代码，它确实附加到旧会话中，但是在调用网络驱动程序远程（）它使另一个浏览器启动！！无缘无故？这是Mac上的，其他人有这个问题吗？（这使得这个功能没用）

谁能告诉我我做错了什么吗？在

from selenium import webdriver

driver = webdriver.Chrome()
url = driver.command_executor._url
session_id = driver.session_id 

driver.get('https://www.w3schools.com/html/tryit.asp?filename=tryhtml_intro')

driver2 = webdriver.Remote(command_executor=url,desired_capabilities={})
driver2.session_id = session_id

driver2.get("http://www.wikipedia.in")

Answer 1

您可以这样做，但它需要对selenium代码进行一些修补。这可以使用python中的monkey补丁来完成。下面是相同的代码

from selenium import webdriver

driver = webdriver.Firefox()
executor_url = driver.command_executor._url
session_id = driver.session_id
driver.get("http://tarunlalwani.com")

print session_id
print executor_url

def create_driver_session(session_id, executor_url):
    from selenium.webdriver.remote.webdriver import WebDriver as RemoteWebDriver

    # Save the original function, so we can revert our patch
    org_command_execute = RemoteWebDriver.execute

    def new_command_execute(self, command, params=None):
        if command == "newSession":
            # Mock the response
            return {'success': 0, 'value': None, 'sessionId': session_id}
        else:
            return org_command_execute(self, command, params)

    # Patch the function before creating the driver object
    RemoteWebDriver.execute = new_command_execute

    new_driver = webdriver.Remote(command_executor=executor_url, desired_capabilities={})
    new_driver.session_id = session_id

    # Replace the patched function with original function
    RemoteWebDriver.execute = org_command_execute

    return new_driver

driver2 = create_driver_session(session_id, executor_url)
print driver2.current_url

解决方案的关键不是让newSession命令通过原始驱动程序执行，而是处理它发送我们自己现有的会话id
