When I try to log out from the testing page, there occurs an connection refused error. This is the command / code I've used:
当我尝试从测试页面注销时，会出现连接拒绝错误。这是我用过的命令/代码：
driver.find_element_by_xpath("//a[@href = '/logged/pages/user/logout.php']").click()
I also tried by linktext, or ActionChains, the same error. And it happens sometime, not always, Any comments?
我也尝试过linktext或ActionChains，同样的错误。它发生在某个时候，并不总是，任何评论？
The Error Message:
错误消息：
<urlopen error [Errno 111] Connection refused>

This is a temporary connectivity issue between your Selenium language bindings and a Selenium server. This may happen more often if you are using a remote Selenium server on a different machine and especially if it goes over the internet. We've, for instance, seen this kind of errors when using remote selenium servers at BrowserStack or Sauce Labs.
这是Selenium语言绑定和Selenium服务器之间的临时连接问题。如果您在不同的计算机上使用远程Selenium服务器，特别是如果它通过Internet，则可能会更频繁地发生这种情况。例如，我们在BrowserStack或Sauce Labs使用远程selenium服务器时看到了这种错误。
Since Python/Selenium bindings don't have an automatic way to retry JSON wire (JSON over HTTP) requests/commands, you are forced to handle it in your code. For instance, if these are tests you are executing - a common way to tackle these errors is to retry failed tests 3 times and, only if all 3 attempts fail - report a failed test.
由于Python / Selenium绑定没有自动重试JSON wire（JSON over HTTP）请求/命令的方法，因此您必须在代码中处理它。例如，如果这些是您正在执行的测试 - 解决这些错误的常用方法是重试失败的测试3次，并且只有当所有3次尝试都失败时 - 报告测试失败。
