python - 将 -profile 参数添加到 python selenium 选项时，Firefox 连接被拒绝

Question

我正在尝试在 python 中为我的 Firefox selenium 驱动程序的启动添加选项以捕获崩溃数据。我用来启动驱动程序的函数如下所示：

import os 
from selenium import webdriver  
from selenium.webdriver.firefox.options import Options as FFOptions
from selenium.webdriver.firefox.webdriver import WebDriver as FirefoxWebDriver 
import tempfile
SELENIUM_TEMP_DIR = os.path.abspath('./data/raw')


def get_local_firefox_driver():
    
    os.environ['MOZ_FORCE_DISABLE_E10S'] = '1'
    ff_options = FFOptions()

    # Add custom crash dump folder
    profile_temp = tempfile.mkdtemp(".selenium", dir=SELENIUM_TEMP_DIR)
    print("*** Using profile: {}".format(profile_temp))
    ff_options.add_argument("-profile")
    ff_options.add_argument(profile_temp)

    ff_profile = webdriver.FirefoxProfile()
    # set some privacy settings
    ff_profile.set_preference("places.history.enabled", False)
    ff_profile.set_preference("privacy.clearOnShutdown.offlineApps", True)
    ff_profile.set_preference("privacy.clearOnShutdown.passwords", True)
    ff_profile.set_preference("privacy.clearOnShutdown.siteSettings", True)
    ff_profile.set_preference("privacy.sanitize.sanitizeOnShutdown", True)
    ff_profile.set_preference("signon.rememberSignons", False)
    ff_profile.set_preference("network.cookie.lifetimePolicy", 2)
    ff_profile.set_preference("network.dns.disablePrefetch", True)
    ff_profile.set_preference("network.http.sendRefererHeader", 0)
    ff_profile.set_preference("permissions.default.image", 2)

    driver = webdriver.Firefox(firefox_profile=ff_profile, options=ff_options)
    return driver

当我尝试使用此版本的功能启动驱动程序时，出现此错误：

Traceback (most recent call last):
  File "/Users/username/project_name/error_demo.py", line 2, in <module>
    driver = get_local_firefox_driver(headless=False)
  File "/Users/username/project_name/src/selenium_helper.py", line 129, in get_local_firefox_driver
    driver = webdriver.Firefox(firefox_profile=ff_profile, options=ff_options, capabilities=ff_capabilities)

    keep_alive=True)
  File "/Users/username/miniconda3/envs/live_auction/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/Users/username/miniconda3/envs/live_auction/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/Users/username/miniconda3/envs/live_auction/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/Users/username/miniconda3/envs/live_auction/lib/python3.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: connection refused

在崩溃期间，Firefox 实际上打开并且看起来像这样：

如果我注释掉旨在捕获崩溃数据的代码部分

# Add custom crash dump folder
profile_temp = tempfile.mkdtemp(".selenium", dir=SELENIUM_TEMP_DIR)
print("*** Using profile: {}".format(profile_temp))
ff_options.add_argument("-profile")
ff_options.add_argument(profile_temp)

我没有收到任何错误，Firefox 浏览器的打开方式如下：

需要如何get_local_firefox_driver()修改才能使 Firefox 和 geckodriver 能够正确启动并具有捕获崩溃数据的能力？

我认为这样的事情应该有效：

import tempfile

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

# Custom profile folder to keep the minidump files
profile = tempfile.mkdtemp(".selenium")
print("*** Using profile: {}".format(profile))

# Use the above folder as custom profile
opts = Options()
opts.add_argument("-profile")
opts.add_argument(profile)
opts.binary = "/Applications/Firefox.app/Contents/MacOS/firefox"

driver = webdriver.Firefox(options=opts,
    # hard-code the Marionette port so geckodriver can connect
    service_args=["--marionette-port", "2828"])

# Your test code which crashes Firefox

如果这不起作用，我建议您查看官方文档
