Selenium会话重用 - 猴子补丁密钥错误

标签: python selenium chromium session-reuse

在尝试将硒重新连接到铬会议时,我遇到了一个错误的错误:

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)

要重新连接会话而不初始化新窗口,使用猴子补丁from another stackoverflow question - 粘贴在@TarunLalwani下面

    browser = webdriver.Chrome(executable_path=path_to_chrome)
    browser.get(url)

这个猴子补丁正在改变发生错误的钥匙,所以我相信问题就在那里,但我不太明白猴子补丁发生了什么。

如果猴子补丁尚未作为一个函数加载, 运行,但如果它已经加载,则不会运行,因此会出现上述错误。

此外,在加载猴子补丁后运行以下

<ipython-input-4-9615267dd764> in new_command_execute(self, command, params)
     14             return {'success': 0, 'value': None, 'sessionId': 
session_id}
     15         else:
---> 16             return org_command_execute(self, command, params)

会导致错误,即使我只是调用webdriver而不是尝试重用会话,这似乎也在访问猴子补丁。

我如何尝试解决此问题?

1 个答案:

答案 0 :(得分:0)

而不是修复上述内容,我只是在函数外部声明浏览器并将其传递给我正在使用的函数。例如:

browser = webdriver.Chrome(executable_path=path_to_chrome)
browser.get(url)

somefunction(browser)

而不是

somefunction(session_id, session_url)

在某些方面不那么优雅,但更简单。
