Python MaxRetryError:HTTPConnectionPool:超过最大重试次数（由协议错误（'；连接中止。'；，错误（111，'；连接被拒绝'；）引起）,python,selenium,selenium-webdriver,python-requests,urllib3,Python,Selenium,Selenium Webdriver,Python Requests,Urllib3,我有一个问题：我想测试“选择”和“输入”。我可以像下面的代码那样编写它吗原始代码： 12 class Sinaselecttest(unittest.TestCase): 13 14 def setUp(self): 15 binary = FirefoxBinary('/usr/local/firefox/firefox') 16 self.driver = webdriver.Firefox(firefox_binary=binary)

我有一个问题：我想测试“选择”和“输入”。我可以像下面的代码那样编写它吗原始代码：

 12 class Sinaselecttest(unittest.TestCase):
 13 
 14     def setUp(self):
 15         binary = FirefoxBinary('/usr/local/firefox/firefox')
 16         self.driver = webdriver.Firefox(firefox_binary=binary)
 17 
 18     def test_select_in_sina(self):
 19         driver = self.driver
 20         driver.get("https://www.sina.com.cn/")
 21         try:
 22             WebDriverWait(driver,30).until(
 23                 ec.visibility_of_element_located((By.XPATH,"/html/body/div[9]/div/div[1]/form/div[3]/input"))
 24             )
 25         finally:
 26             driver.quit()
 # #测试select功能
 27         select=Select(driver.find_element_by_xpath("//*[@id='slt_01']")).select_by_value("微博")
 28         element=driver.find_element_by_xpath("/html/body/div[9]/div/div[1]/form/div[3]/input")
 29         element.send_keys("杨幂")
 30         driver.find_element_by_xpath("/html/body/div[9]/div/div[1]/form/input").click()
 31         driver.implicitly_wait(5)

 32    def tearDown(self):
 33        self.driver.close()

我想测试Selenium的“选择”功能。所以我选择新浪网站选择一个选项，并在textarea中输入文本。然后搜索它。但当我运行此测试时，它出现错误：

    Ran 1 test in 72.106s

谁能告诉我为什么？谢谢这个错误消息

MaxRetryError: HTTPConnectionPool(host='127.0.0.1', port=51379): Max retries exceeded with url: /session/2e64d2a1-3c7f-4221-96fe-9d0b1c102195/window (Caused by ProtocolError('Connection aborted.', error(111, 'Connection refused')))

…表示调用self.driver.close（）
方法失败，无法引发MaxRetryError

有几件事：

首先也是最重要的是，根据讨论，追溯有些误导。请求包装异常以方便用户。原始异常是显示的消息的一部分
请求从不重试（它为urllib3的
```
HTTPConnectionPool
```
设置
```
retries=0
```
），因此如果没有MaxRetryError和HTTPConnectionPool关键字，错误会更加规范。因此，理想的回溯应该是：
```
  ConnectionError(<class 'socket.error'>: [Errno 1111] Connection refused)
```
合并是：

结论升级到Selenium 3.14.1后，您将能够设置超时并查看规范回溯，并能够采取所需的操作
