urllib3.exceptions.MaxRetryError： HTTPConnectionPool(host='localhost'， port=59587)： 使用 Selenium Ge

Question

黎明时分我的代码工作得很好，但今天当我醒来时它不再工作了，我没有改变任何一行代码，我也检查了Firefox是否更新，不，它没有，我不知道可能是什么，我一直在阅读urllib文档，但我找不到任何信息

firefox_options.add_argument("--headless")
webdriver = webdriver.Firefox(
executable_path = firefox_driver_path,
options = firefox_options)
with webdriver as driver:
    driver.get(url)
    wait = WebDriverWait(driver, 25)
wait.until(presence_of_element_located((By.CSS_SELECTOR, "div#roulette.page.complete")))
time.sleep(2)
results = driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")
for quote in results:
      quote.text.split('n')
data = [my_elem.text for my_elem in driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")][:8]
#método convertElements, converte elementos da lista em elementos declarados
def convertElements( oldlist, convert_dict ):
    newlist = []
    for e in oldlist:
      if e in convert_dict:
        newlist.append(convert_dict[e])
      else:
        newlist.append(e)
    return newlist
#fim do método
colors = convertElements(data, {'':"white",'1':"red",'2':"red",'3':"red",'4':"red",'5':"red",'6':"red",'7':"red",'8':"black",'9':"black",'10':"black",'11':"black",'12':"black",'13':"black",'14':"black"})
print(colors)

它工作得很好，从周日开始我一直在编码，它一直在工作

Answer 1

这个错误信息…

MaxRetryError(_pool, url, error or ResponseError(cause))urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='localhost', port=59587): Max retries exceeded with url: /session/b38be2fe-6d92-464f-a096-c43183aef6a8/element (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x00000173145EF520>: Failed to establish a new connection: [WinError 10061] No connections could be made because the target machine actively refused them'))

…暗示GeckoDriver无法启动/生成一个新的浏览上下文，即firefox会话。

根源此错误的根本原因可能是以下任何一种:

• 这个错误可能会出现，如果已经关闭了浏览上下文手动与暴力，当驱动程序已经启动了元素/元素的监视
。
• 有可能你正在尝试访问的应用程序正在限制来自你的系统/机器/ip-address/网络的请求。
• 也有可能应用程序已经识别出Selenium驱动的GeckoDriver发起的firefox 浏览上下文是一个bot，并且拒绝任何访问。

---

解决方案

确保:

• 要逃避作为bot的检测，请传递参数 --disable-blink-features=AutomationControlled ，如下所示:

  from selenium.webdriver.firefox.options import Options
  options = Options()
  options.add_argument('--disable-blink-features=AutomationControlled')
  

• 总是在tearDown(){}方法中调用driver.quit()来关闭&销毁WebDriver和Web Client实例。

• 诱导WebDriverWait同步快速移动的WebDriver与浏览上下文。

Answer 2

得到了同样的问题，而试图生成的情况下，我需要重新启动我的驱动程序，如果它失败的某种原因(同时定位任何HTML元素)，所以我只是重新声明了驱动程序配置(如下所示):

try:
    ## driver config
    driver = webdriver.Chrome(
        service=service, 
        options=options
    )
    run_script(driver)
except:
    # if the driver fails to load an element, then quit the driver
    driver.quit()
    print("nScrapper stopped, launching again in 4 seconds...")
    time.sleep(4)
    ## driver config
    driver = webdriver.Chrome(
        service=service, 
        options=options
    )
    time.sleep(3)
    run_script(driver)

Answer 3

昨天遇到了同样的错误。尝试quit()驱动程序并重新激活驱动程序。这对我很有效。输入图片描述
