集线器关闭或没有响应:在用户代理值为23处意外的char0x131: selenium/3.14.0 ( SeleniumGrid v3.14.0 )

Question

我有selenium独立服务器3.14.0，希望运行hub，然后在其上注册节点。我第一次运行中心就像

java -jar selenium-server-standalone-3.14.0.jar -role hub

它工作得很好，并等待节点注册。然后运行这些命令来注册一个节点，

java -jar selenium-server-standalone-3.14.0.jar -role node -hub http://localhost:4444/register/grid -browser browserName=chrome,platform=WINDOWS

但是它不断地给我这个错误，我不能注册任何节点。

11:30:47.634 INFO [SelfRegisteringRemote$1.run] - Couldn't register this node: The hub is down or not responding: Unexpected char 0x131 at 23 in User-Agent value: selenium/3.14.0 (java w²ndows)

我该如何解决这个问题？

• 我有最新版本的铬驱动器。

Answer 1

这个错误信息..。

[SelfRegisteringRemote$1.run] - Couldn't register this node: The hub is down or not responding: Unexpected char 0x131 at 23 in User-Agent value: selenium/3.14.0 (java w²ndows)

表示Selenium Grid节点没有注册到Selenium Grid中心的...implies。

您的主要问题是您的底层操作系统没有使用英语。

解决方案

在操作系统的英语版本中，尝试同样的方法，命令可以正常工作，不会有任何问题。

除此之外，我看不出你的命令有任何这样的问题。

启动Selenium Grid集线器的命令非常完善：

java -jar selenium-server-standalone-3.14.0.jar -role hub

您应该看到以下启动日志：

C:\Utility\SeleniumGrid>java -jar selenium-server-standalone-3.14.0.jar -role hub
14:31:09.654 INFO [GridLauncherV3.launch] - Selenium build info: version: '3.14.0', revision: 'aacccce0'
14:31:09.659 INFO [GridLauncherV3$2.launch] - Launching Selenium Grid hub on port 4444

14:31:11.088 INFO [Hub.start] - Clients should connect to http://192.168.1.5:4444/wd/hub

启动Selenium Grid节点的命令也很完美：

java -jar selenium-server-standalone-3.14.0.jar -role node -hub http://localhost:4444/register/grid -browser browserName=chrome,platform=WINDOWS

您应该看到以下启动日志：

C:\Utility\SeleniumGrid>java -jar selenium-server-standalone-3.14.0.jar -role node -hub http://localhost:4444/register/grid -browser browserName=chrome,platform=WINDOWS

网格控制台位于http://localhost:4444/grid/console，如下所示：
