我有一个Java Web应用程序，我在其中集成了一些Selenium代码，它基本上完成了以下工作：当我从远程系统访问URL时，它会在我的服务器上打开浏览器。
我正在尝试以编程方式在集线器上创建节点。已成功创建集线器，但未创建该节点。
这是我的代码：
try {
GridHubConfiguration config = new GridHubConfiguration();
config.setHost("localhost");
config.setPort(4444);
Hub hub = new Hub(config);
hub.start();
SelfRegisteringRemote node = null;
RegistrationRequest req = new RegistrationRequest();
// Create capabilities instance
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setBrowserName(DesiredCapabilities.firefox().getBrowserName());
capabilities.setCapability(RegistrationRequest.MAX_INSTANCES,5);
// Set configurations for registration request
Map<String, Object> nodeConfig = new HashMap<String, Object>();
nodeConfig.put(RegistrationRequest.AUTO_REGISTER, true);
nodeConfig.put(RegistrationRequest.HUB_HOST, hub.getHost());
nodeConfig.put(RegistrationRequest.HUB_PORT, hub.getPort());
nodeConfig.put(RegistrationRequest.PORT, 5555);
URL remoteURL = null;
remoteURL = new URL("http://" + hub.getHost() + ":" + 8080);
nodeConfig.put(RegistrationRequest.PROXY_CLASS,
"org.openqa.grid.selenium.proxy.DefaultRemoteProxy");
nodeConfig.put(RegistrationRequest.MAX_SESSION, 5);
nodeConfig.put(RegistrationRequest.CLEAN_UP_CYCLE, 2000);
nodeConfig.put(RegistrationRequest.REMOTE_HOST, remoteURL);
nodeConfig.put(RegistrationRequest.MAX_INSTANCES, 5);
String nodeUrl = "http://"+hub.getHost()+":8080/wd/hub";
DesiredCapabilities capability = DesiredCapabilities.chrome();
driver = new RemoteWebDriver(new URL(nodeUrl),capability);
driver.get("http://www.facebook.com");
} catch (Exception e) {
e.printStackTrace();
}
这就是我得到的：
