我正在尝试使用selenium-server-standalone-3.0.1在WIN10上启动Microsoft Edge . 在创建驱动程序实例时，浏览器在节点上打开正常，但随后进程挂起大约一分钟左右，生成以下错误，导致驱动程序对象返回NULL . 这是错误消息：

org.openqa.selenium.WebDriverException: Error forwarding the new session Error forwarding the request Read timed out Command duration or timeout: 134.17 seconds Build info: version: '3.4.0', revision: 'unknown' ...

请记住 - 这适用于Chrome .

另请注意：

  • 我可以从Node上的Edge浏览器ping我的HUB机器URL

  • 我试过以下版本，结果相同：3.0.1,3.3.1,3.5.0,3.5.3

Here is my hubConfig:

{
  "host": {hidden for security},
  "port": 4444,
  "newSessionWaitTimeout": -1,
  "servlets" : [],
  "withoutServlets": [],
  "custom": {},
  "capabilityMatcher": "org.openqa.grid.internal.utils.DefaultCapabilityMatcher",
  "throwOnCapabilityNotPresent": true,
  "cleanUpCycle": 5000,
  "role": "hub",
  "debug": true,
  "browserTimeout": 60,
  "timeout": 1800
}

And here is my nodeConfig

{
  "capabilities":
  [
    {
      "browserName": "MicrosoftEdge",
      "maxInstances": 5,
      "platform": "WIN10"
    }
  ],
  "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
  "maxSession": 5,
  "port": 5555,
  "register": true,
  "registerCycle": 500000,
  "hub": "http://{hidden for security}:4444/grid/register",
  "nodeStatusCheckTimeout": 5000,
  "nodePolling": 500000,
  "role": "node",
  "unregisterIfStillDownAfter": 60000,
  "downPollingLimit": 2,
  "debug": true,
  "servlets" : [],
  "withoutServlets": [],
  "custom": {},
  "browserTimeout": 60,
  "timeout": 1800
}

My Command to start the HUB

java -jar selenium-server-standalone-3.0.1.jar -role hub -hubConfig hubConfig.json

And to start the node:

java "-Dwebdriver.edge.driver=C:\Selenium\EdgeDriver\MicrosoftWebDriver.exe" -jar selenium-server-standalone-3.0.1.jar -role node -nodeConfig nodeConfig.json

当我这样做时，我可以看到节点在集线器上注册正常（它必须是或者我将无法启动浏览器！）

Here is my java code to create the driver object

DesiredCapabilities capability = DesiredCapabilities.edge(); capability.setBrowserName("MicrosoftEdge");
    capability.setCapability(CapabilityType.PLATFORM, Platform.WIN10);
    driver = new RemoteWebDriver(new URL("http://{hidden for security}:4444/wd/hub"),capability);

Here is the log output for the node
