Question

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()

我也尝试过linktext或ActionChains，同样的错误。它发生在某个时间，并不总是，任何评论？

错误讯息：

<urlopen error [Errno 111] Connection refused>

这是Selenium语言绑定与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。

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。

urlopen错误[Errno 111]连接拒绝了selenium python
