java - 指定ChromeDriver运行的端口

Question

H 社区，我正在尝试在 EC2 服务器上设置 Selenium Grid，以下是我迄今为止采取的步骤。

1.在端口4044上启动集线器

java -jar /ebst/wrangler/upla/bin/selenium-server-standalone-3.141.59.jar -role hub -port 4044

2.在4045上注册节点

java -Dwebdriver.chrome.driver="~/chromedriver" -jar ~/selenium-server-standalone-3.141.59.jar -role node -hub http://hubURL:4044/grid/register -port 4045

3.在我的 Java 代码中启动 Webdriver

import cucumber.api.java.Before;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

import java.net.MalformedURLException;
import java.net.URL;


public class Test {
    WebDriver driver;

    @Before
    public void setup() throws MalformedURLException {

        String nodeURL = "http://hubURL:4044/wd/hub";
        System.out.println("setting up");

        DesiredCapabilities desiredCapabilities = DesiredCapabilities.chrome();
        desiredCapabilities.setBrowserName("chrome");

        desiredCapabilities.setPlatform(Platform.LINUX);

        ChromeOptions chromeOptions = new ChromeOptions();

        chromeOptions.addArguments(
                "--verbose",
                "--headless",
                "--disable-web-security",
                "--ignore-certificate-errors",
                "--allow-running-insecure-content",
                "--allow-insecure-localhost",
                "--no-sandbox",
                "--disable-gpu");

        chromeOptions.merge(desiredCapabilities);

        driver = new RemoteWebDriver(new URL(nodeURL), chromeOptions);
        System.out.println("setting up done");

    }
}

在控制台上，由于超时，我收到以下错误。

org.openqa.selenium.WebDriverException: unknown error: cannot find Chrome binary

(Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Linux 3.10.0-1062.el7.x86_64 x86_64) (WARNING: The server did not provide any stacktrace information)

Driver info: driver.version: unknown Command duration or timeout: 523 milliseconds

当我导航回节点服务器时，这是显示的消息。

22:44:05.604 INFO [ActiveSessionFactory.lambda$apply$11] - Matched factory org.openqa.selenium.grid.session.remote.ServicedSession$Factory (provider: org.openqa.selenium.chrome.ChromeDriverService)

Starting ChromeDriver 74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}) on port 3459

Only local connections are allowed.

Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

[1567550645.675][SEVERE]: bind() failed: Cannot assign requested address (99)

22:44:05.988 INFO [ActiveSessionFactory.apply] - Capabilities are: { "browserName": "chrome", "goog:chromeOptions": { "args": [ "--verbose", "--headless", "--disable-web-security", "--ignore-certificate-errors", "--allow-running-insecure-content", "--allow-insecure-localhost", "--no-sandbox", "--port:4040", "--disable-gpu" ], "extensions": [ ] }, "platform": "LINUX", "version": "" }

据我所知，发生该错误是因为在我们公司内部，只有某些端口可用，并且 ChromeDriver 每次都会在随机端口上启动。为了指定此 ChromeDriver 每次启动的端口，我在 Java 代码中尝试了 ChromeOptions 和 RemoteWebDriver 的各种规范，但没有成功。

其他人也遇到过这个问题吗？如果可以的话，您能给我一些该怎么做的建议吗？或者更广泛地说，这是在 EC2 上启动 selenium 服务器的正确方法吗？ 任何帮助将不胜感激!

尝试将 -Dwebdriver.chrome.whitelistedIps= 传递到 chromedriver

java -Dwebdriver.chrome.driver="~/chromedriver" -Dwebdriver.chrome.whitelistedIps= -jar ~/selenium-server-standalone-3.141.59.jar -role node -hub http://hubURL:4044/grid/register -port 4045
