英文:
Why am I getting "Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure." error
问题
使用Selenium Grid，我有一个注册了一个节点的Hub。Hub和Node位于不同的网络上。以下是Hub和Node的配置：
如果我理解错误，请纠正我，但在我看来，这一切都是正确的。但问题在于，当我运行我的Java代码（在与Hub和Node不同网络的不同计算机上）时，我会收到此错误消息：
构建信息：版本：'3.141.59'，修订版本：'e82be7d358'，时间：'2018-11-14T08:25:53'
系统信息：主机：'NROLL97'，IP：'192.168.86.31'，操作系统名称：'Windows 10'，操作系统架构：'amd64'，操作系统版本：'10.0'，Java版本：'1.8.0_261'
驱动程序信息：驱动程序版本：RemoteWebDriver
系统信息对于我从其运行Java项目的计算机是正确的，但我觉得它应该显示具有远程Web驱动程序（即将实际运行测试的AWS Linux 2计算机）的计算机的系统信息。由于它显示具有远程Web驱动程序的版本，我认为它也应该向我提供具有远程Web驱动程序的计算机的系统信息。
这个错误消息几乎没有用；在Stack Overflow上已经有很多关于这个问题的回答，大多数回答都会告诉我确保我有正确的版本。我可以确定这不是问题，因为当我在本地测试时，这些相同的版本是可行的。
这是我的DriverInit类：
public class DriverInit {
public WebDriver driver;
public ChromeOptions chromeOptions;
public DesiredCapabilities caps;
public static final String URL = "http://3.128.83.181/:4444/wd/hub";
DriverInit(int row) throws MalformedURLException {
// 用于本地自动化测试
// this.chromeOptions = new ChromeOptions();
// this.chromeOptions.addArguments("--headless");
// String chromeDriverPath = "resources/chromedriver.exe";
// System.setProperty("webdriver.chrome.driver", chromeDriverPath);
// this.driver = new ChromeDriver();
// this.driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
// 用于AWS
ChromeOptions options = new ChromeOptions();
options.setCapability(CapabilityType.BROWSER_NAME, "chrome");
options.addArguments("--headless");
options.setCapability(CapabilityType.PLATFORM_NAME, Platform.LINUX);
driver = new RemoteWebDriver(new URL(URL), options);
driver.manage().window().maximize();
}
public WebDriver getDriver() {
return this.driver;
}
}
英文:
Using Selenium Grid, I have a hub that has one node registered to it. The Hub and Node are on different networks. These are the configurations for the Hub and the Node:
Please correct me if I am wrong, but this all looks correct to me. But the problem is that when I run my Java code (on a different computer and in a different network from the hub and node), I get this error:
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:53'
System info: host: 'NROLL97', ip: '192.168.86.31', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_261'
Driver info: driver.version: RemoteWebDriver
The system info is correct for the machine that I am running my java project from, but I feel like it should be showing the System Info of the machine that has the remote web driver (which is an AWS Linux 2 machine) where the test will actually be ran. Since it is showing that it has a version for the remote web driver, I would think it would also tell me the System Info of the machine with the remote web driver.
The error message is almost useless; the majority of answers to this question already on SO will tell me to be sure I have the correct versions. I am certain that is not the issue, because these same versions work when I test locally.
And this is my DriverInit class:
public class DriverInit{
public WebDriver driver;
public ChromeOptions chromeOptions;
public DesiredCapabilities caps;
public static final String URL = "http://3.128.83.181/:4444/wd/hub";
DriverInit(int row) throws MalformedURLException {
// for local automated testing
// this.chromeOptions = new ChromeOptions();
// this.chromeOptions.addArguments("--headless");
// String chromeDriverPath = "resources/chromedriver.exe";
// System.setProperty("webdriver.chrome.driver", chromeDriverPath);
// this.driver = new ChromeDriver();
// this.driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
// FOR AWS
ChromeOptions options = new ChromeOptions();
options.setCapability(CapabilityType.BROWSER_NAME, "chrome");
options.addArguments("--headless");
options.setCapability(CapabilityType.PLATFORM_NAME, Platform.LINUX);
driver = new RemoteWebDriver(new URL(URL), options);
driver.manage().window().maximize();
}
public WebDriver getDriver() {
return this.driver;
}
}

错误出在URL中。"http://3.128.83.181/:4444/wd/hub"; 需要修改为 "http://3.128.83.181:4444/wd/hub";。
英文:
The error is in the URL. "http://3.128.83.181/:4444/wd/hub"; needed to be changed to "http://3.128.83.181:4444/wd/hub";
