python - 在几次成功的 Selenium Geckodriver 任务后连接被拒绝(操作系统错误 111)(Python)

Question

操作系统:Ubuntu 20.04 无 GUI。

我正在 headless 模式下做一个非常简单的任务:

1. 安装并启用 firefox 插件。
2. 导航到 about:debugging#/runtime/this-firefox 并获取插件的 uuid。

问题是，在一些成功的 .py 脚本完成后，下一个脚本会挂起并返回连接被拒绝(操作系统错误 111)错误。之后，我必须重新启动服务器，这只解决了几个 .py 脚本启动的问题。

我的代码:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium.webdriver import FirefoxProfile
import time

ff_options = FirefoxOptions()

user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) ff/85.0.4183.83 Safari/537.36"

ff_options.add_argument('-headless')
ff_options.add_argument(f'user-agent={user_agent}')
ff_options.add_argument('--disable-dev-shm-usage')
ff_options.add_argument('--no-sandbox')
ff_options.add_argument("--window-size=1920,1080")
ff_options.add_argument('--ignore-certificate-errors')
ff_options.add_argument('--allow-running-insecure-content')
ff_options.add_argument("--proxy-server='direct://'")
ff_options.add_argument("--proxy-bypass-list=*")
ff_options.add_argument("--start-maximized")
ff_options.add_argument('--disable-gpu')
ff_options.add_argument('--disable-setuid-sandbox')

buster = "/root/my_simple_extension.xpi"

driver = webdriver.Firefox(executable_path='/usr/local/share/geckodriver', options=ff_options)
driver.install_addon(buster, temporary=True)
driver.profile = webdriver.FirefoxProfile()
driver.profile.add_extension(buster)
driver.profile.set_preference("security.fileuri.strict_origin_policy", False)
driver.profile.update_preferences()

driver.get("about:debugging#/runtime/this-firefox")

time.sleep(1)

parent1 = driver.find_element_by_xpath('(//div[@class="fieldpair"])[position()=3]')
uuid = parent1.text.splitlines()[1]

driver.get('moz-extension://{}/home.html'.format(uuid))
time.sleep(1)
print(driver.page_source)
driver.quit()

只有测试的源代码并不能真正帮助为您的问题提供合格的答案。因此请create trace logs在测试运行时与我们分享这些。记录到文件(在您的情况下应该是 geckodriver.log)的附加信息可以帮助了解情况，并最终提出解决方案。谢谢。
