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

问题描述

我在所有浏览器中都遇到了这个例外.例如，我在chrome上创建一个远程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，如下所示:

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.

但是我在http://myIP:4444/grid/console处检查了我的硒集线器，一切都很好，该节点是stil注册的.然后，我在http://myIP:5555/wd/hub/static/resource/hub.html上检查我的节点，仍然可以单击创建会话"为所有浏览器创建一个会话.

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.

我今天才遇到这个异常，它在几天前仍然有效.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Google搜索，但是当我的网格仍在运行时，找不到解决方案.任何帮助，不胜感激.

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()`

调用 RemoteWebDriver 时 Selenium 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文档上的文档更新.以下是 Selenium发行说明的相关字节:

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`.
