Remote WebDriver UnreachableBrowserException:无法启动新会话 [英] Remote WebDriver UnreachableBrowserException: Could not start a new session

问题描述

我对所有浏览器都有这个例外.例如，我在 chrome 上创建了一个远程 webdriver，如下所示:

I got this exception for all browsers. For example, I create a remote webdriver on chrome like this:

caps = DesiredCapabilities.chrome();
ChromeOptions options = new ChromeOptions();
options.addArguments("disable-infobars");
caps.setCapability(ChromeOptions.CAPABILITY, options);
webDriver = new RemoteWebDriver(new URL("http://myIP:5555/wd/hub"), caps);

我得到了 UnreachableBrowserException 如下:

And I got UnreachableBrowserException as follow:

org.openqa.selenium.remote.DesiredCapabilities chrome
INFO: Using `new ChromeOptions()` is preferred to `DesiredCapabilities.chrome()`

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

但我在 http://myIP:4444/grid/console 检查了我的 selenium hub，一切都很好，节点仍然注册.然后我在 http://myIP:5555/wd/hub/static/resource/hub.html 检查我的节点，我仍然可以单击创建会话"为所有浏览器创建会话.

But I check my selenium hub at http://myIP:4444/grid/console, everything is fine, the node is stil registered. I then check my node at http://myIP:5555/wd/hub/static/resource/hub.html, I still can click "Create Session" to create a session for all browsers.

我今天刚得到这个异常，几天前它仍然有效.我正在使用 Selenium 3.11.0、IntelliJ 2017.3，所有驱动程序和浏览器都是最新版本.

I just got this exception today, it still worked few days ago. I am using Selenium 3.11.0, IntelliJ 2017.3, all drivers and browsers are latest versions.

我在这里用谷歌搜索过，但是当我的网格仍在运行时，我找不到解决方案.非常感谢任何帮助.

I googled here, but I can't find a solution for this while my gird is still running. Any help much appreciated.

推荐答案

错误说明了一切:

INFO: Using `new ChromeOptions()` is preferred to `DesiredCapabilities.chrome()`

Selenium 在调用 RemoteWebDriver 时的当前实现支持 ChromeOptions，您可以使用以下代码块:

The current implementation of Selenium while invoking RemoteWebDriver supports the ChromeOptions and you can use the following code block :

ChromeOptions options = new ChromeOptions();
options.addArguments("disable-infobars");
webDriver = new RemoteWebDriver(new URL("http://myIP:5555/wd/hub"), options);

更新

根据您的评论更新 seleniumhq-documentation 上的文档更新.以下是 Selenium 发行说明 中的相关字节:

Update

As per your comment update the documentation at seleniumhq-documentation is yet to be updated. Here are the relevant bytes from the Selenium Release Notes :

• Selenium v​​3.5.0:

* Start making *Option classes instances of Capabilities. This allows
  the user to do:
  `WebDriver driver = new RemoteWebDriver(new InternetExplorerOptions());`

Selenium v​​3.6.0:

* All `*Option` classes now extend `MutableCapbilities`
  `new RemoteWebDriver(new ChromeOptions());`

Selenium v​​3.7.0:

* Migrated from using `DesiredCapabilities` to either
  `MutableCapabilities` or (preferably) `ImmutableCapabilities`.
