ConnectionAbortedError: [WinError 10053] 已建立的连接被主机中的软件中止

由于某种原因，我收到以下错误only当我打开一个嵌套的webdriver实例。不知道这里发生了什么。

我在用Windows 10， 壁虎驱动程序 0.21.0, and Python 3.7。

连接中止错误：[WinError 10053]

An established connection was aborted by the software in your host machine

部分脚本运行良好

tab_backers = ff.find_element_by_xpath('//a[@gogo-test="backers_tab"]')

try:
    funding_backers_count = int(''.join(filter(str.isdigit, str(tab_backers.text))))
except ValueError:
    funding_backers_count = 0

if funding_backers_count > 0:
    tab_backers.click()

    see_more_backers = WebDriverWait(ff, 10).until(
        EC.element_to_be_clickable((By.XPATH, '//ui-view//a[text()="See More Backers"]'))
    )
    clicks = 0
    while clicks < 0:
        clicks += 1
        ff.WebDriverWait(ff, 5).until(
            see_more_backers.click()
        )

    for container in ff.find_elements_by_xpath('//ui-view//div[@class="campaignBackers-pledge ng-scope"]'):
        backers_profile = container.find_elements_by_xpath('./*/div[@class="campaignBackers-pledge-backer-details"]/a')
        if len(backers_profile) > 0:
            backers_profile = backers_profile[0].get_attribute('href') 
        else:
            backers_profile = 'Unknown'
        backers_name = safe_encode(container.find_element_by_xpath('(./*/div[@class="campaignBackers-pledge-backer-details"]/*)[1]').text)
        backers_timestamp = container.find_element_by_xpath('./*/div[@class="campaignBackers-pledge-backer-details"]/div[contains(@class, "campaignBackers-pledge-backer-details-note")]').text
        backers_contribution = container.find_element_by_xpath('./*//*[contains(@class, "campaignBackers-pledge-amount-bold")]').text
        if backers_contribution != 'Private':
            backers_contribution = int(''.join(filter(str.isdigit, str(backers_contribution))))
        if backers_profile != 'Unknown':

部分脚本导致系统中止连接

            _ff = create_webdriver_instance()
            _ff.get(backers_profile)
            _ff.quit()

这是在一个codepen,因为它太长了！

create_webdriver_instance 函数

def create_webdriver_instance():
    options = Options()
    options.add_argument('-headless')
    try:
        ua_string = random.choice(ua_strings)
        profile = webdriver.FirefoxProfile()
        profile.set_preference('general.useragent.override', ua_string)
        return webdriver.Firefox(profile) # profile, firefox_options=options
    except IndexError as error:
        print('\nSection: Function to Create Instances of WebDriver\nCulprit: random.choice(ua_strings)\nIndexError: {}\n'.format(error))
        return webdriver.Firefox() # firefox_options=options

有谁知道可能导致连接中止的原因吗？

这个错误信息...

ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine

...意味着初始化一个新的网页浏览会话 i.e. 火狐浏览器会话被中止。

_{An established connection was aborted by the software in your host machine}

根据您的代码尝试，错误明显出现create_webdriver_instance()函数包含：

try:
    ua_string = random.choice(ua_strings)
    profile = webdriver.FirefoxProfile()
    profile.set_preference('general.useragent.override', ua_string)
    return webdriver.Firefox(profile)

And:

except IndexError as error:
    print('\nSection: Function to Create Instances of WebDriver\nCulprit: random.choice(ua_strings)\nIndexError: {}\n'.format(error))
    return webdriver.Firefox()

因此，目前尚不清楚您在哪个功能中面临这个问题return webdriver.Firefox(profile) or webdriver.Firefox().

也许仔细看看里面的日志codepen表明错误来自webdriver.Firefox(profile).

Reasons

此错误背后可能有多种原因：

• 的存在防病毒软件.
• 防火墙阻止端口。
• 网络配置。
• 问题可能由以下原因引起CORS.
• 由于启用了 HTTP keep-alive 连接

Solution

第一步是查明是否有任何软件阻止您计算机中与服务器的连接。除此之外，可能的解决方案是：

• Disable 防病毒软件.
• Disable firewall.

• 确保系统上的 /etc/hosts 包含以下条目：

  127.0.0.1   localhost.localdomain localhost
  

• As per 连接被主机中的软件中止你需要允许本地主机路由，例如http://localhost:8080/reactive-commands

• As per 与 geckodriver 0.21.0 的保持活动连接在 5 秒不活动后断开，且未使用 Selenium Python 客户端重新连接

  • AutomatedTester: This issue is not because we are not connected at the time of doing a request. If that was the issue we would be getting a httplib.HTTPConnection exception being thrown. Instead a BadStatusLine is thrown when we do a connection and close it and try parse the response. Now this could be the python stdlib bug, httplib bug or selenium bug. A Python client to replace urllib with something else that does not exhibit the same defect with Keep-Alive connections is WIP.

  • andreastt: The geckodriver team is working on extending the server-side timeout value to something more reasonable. As I said, this would help mitigate this issue but not fundamentally fix it. In any case it is true that five seconds is probably too low to get real benefit from persistent HTTP connections, and that increasing it to something like 60 seconds would have greater performance.

结论

Selenium 3.14.0刚刚被释放。如果您受到此问题的影响，请进行相应升级。

参考：

• 带有请求的 Flask 破损管道
• 跨域资源共享 (CORS)
• 连接被主机中的软件中止
• [WinError 10053] 与 0.21.0
• 与 geckodriver 0.21.0 的保持活动连接在 5 秒不活动后断开，且未使用 Selenium Python 客户端重新连接
• 支持保持连接
• 结构体 hyper::server::Server
• Urllib3
