java.net.SocketException 在处理对 {}->http：//ip：port 的请求时捕获：权限被拒绝：通过 VPN 注册Selenium网格节点时

Question

我正在尝试将集线器运行为：

java -jar selenium-server-standalone-2.53.0.jar -role hub

节点为 ：

java -jar selenium-server-standalone-2.53.0.jar -role node -hub http://ip:5555/grid/register -Dwebdriver.ie.driver="C:new folderIEDriverServer.exe" -Dwebdriver.chrome.driver="C:New folderchromedriver.exe" -browser "browserName=internet explorer,version=11,maxInstances=5,seleniumProtocol=WebDriver" -browser "browserName=chrome,version=latest,maxInstances=5,seleniumProtocol=WebDriver" -browser "browserName=firefox,version=25,maxInstances=5,seleniumProtocol=WebDriver"

但是我收到以下错误：

I/O exception (java.net.SocketException) caught when processing request to {}->http://10.97.101.216:5555: Permission denied: connect

此外，我必须在VPN上连接并执行所有这些操作，因此我正在VPN上工作。 请帮忙。

Answer 1

有几件事你需要注意如下：

• 当您启动Selenium Grid Node v2.53.x时，您需要在开头传递WebDriver变体参数，如下所示：

  java -Dwebdriver.chrome.driver=C:\Utility\BrowserDrivers\chromedriver.exe -Dwebdriver.gecko.driver=C:\Utility\BrowserDrivers\geckodriver.exe -Dwebdriver.ie.driver=C:\Utility\BrowserDrivers\IEDriverServer.exe -jar selenium-server-standalone-2.53.1.jar -role node -hub http://192.168.0.105:4444/grid/register
  

• 如果要使用特定的浏览器版本配置Selenium 网格节点 v2.53.x，则需要按如下方式进行具体说明：

  -browser "browserName=firefox,version=60.0.1,maxInstances=5,seleniumProtocol=WebDriver" -browser "browserName=internet explorer,version=10.0,maxInstances=5,seleniumProtocol=WebDriver"
  

• 最后，确保使用正确的网格注册 URI，如下所示：

  java -Dwebdriver.chrome.driver=C:\Utility\BrowserDrivers\chromedriver.exe -Dwebdriver.gecko.driver=C:\Utility\BrowserDrivers\geckodriver.exe -Dwebdriver.ie.driver=C:\Utility\BrowserDrivers\IEDriverServer.exe -jar selenium-server-standalone-2.53.1.jar -role node -hub http://192.168.0.105:4444/grid/register -browser "browserName=chrome,version=66.0,maxInstances=5,seleniumProtocol=WebDriver" -browser "browserName=firefox,version=60.0.1,maxInstances=5,seleniumProtocol=WebDriver" -browser "browserName=internet explorer,version=10.0,maxInstances=5,seleniumProtocol=WebDriver"
