java - CreatePlatformSocket() 返回错误 : An invalid argument was supplied. 端口不可用。在 Chrome 上运行 selenium 代码时退出...

Question

我正在尝试运行以下代码:

package automationFramework;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import appModules.SignIn_Action;
import utility.Constant;
import utility.ExcelUtils;

public class Apache_POI_TC {

    private static WebDriver driver=null;
    public static void main(String[] args) throws Exception {

        ExcelUtils.setExcelFile(Constant.Path_TestData + Constant.File_TestData,"Sheet1");

    System.setProperty("webdriver.chrome.driver","F:\\Chromedriver\\chromedriver_win32\\chromedriver.exe");

            driver = new ChromeDriver();
            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
            driver.get(Constant.URL);
            SignIn_Action.execute(driver);
            System.out.println("Login Successfully, now it is the time to Log Off buddy.");
     driver.quit();
     ExcelUtils.setCellData("Pass", 1, 3);
     }}

但是出现错误:

请建议我如何解决这个问题

此错误消息...

Port not available. Exiting...
May 09, 2018 7:22:30 PM org.openqa.selenium.os.UnixProcess checkForError

...意味着操作系统 Unix 进程无法绑定(bind)到系统内分配的空闲端口。

根据讨论Getting Invalid port error.当分配给 chromedriver 的端口小于 0 或大于 65535 时，会出现错误`“端口无效。正在退出...” 。

但是，从历史上看，根据讨论:

• CreatePlatformSocket() returned an error: An invalid argument was supplied. (0x2726) Port not available. Exiting… with chromedriver and Selenium 3.2
• CreatePlatformSocket() returned an error: An invalid argument was supplied. (0x27t6) Port not available. Exiting… in Selenium Webdriver

据观察，当 ChromeDriver 和 GeckoDriver 通过网络共享时，在初始化浏览器客户端时会出现以下错误:

• 示例 A:

  Starting ChromeDriver 2.28.455520 (cc17746adff54984afff480136733114c6b3704b) on port 12121
  Only local connections are allowed.

  SEVERE: org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)
  org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start.
  

• 样本 B:

  [0.147][SEVERE]: CreatePlatformSocket() returned an error: An invalid argument was supplied. (0x2726) 
  Port not available. Exiting...
  

• 示例 C:

  [1525873930.816][SEVERE]: CreatePlatformSocket() returned an error: An invalid argument was supplied. (0x2726)

  Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
  

• 甚至:

  //chromedriver

  [1530079175.165][INFO]: listen on IPv4 failed with error ERR_INVALID_ARGUMENT

  An invalid argument was supplied. (os error 10022)
  
  //IEDriverServer
  Failed to start the server with: port = '2305', host = '', log level = '', log file = '', whitelisted ips = ''
  

解决方案

• 确保将 ChromeDriver 或 GeckoDriver 放置在主机的本地驱动器中。
• 通过 CLI 执行 netstat 命令来查看是否已达到可能打开的连接数限制，或检查给定端口上是否有其他应用程序正在运行。
• 检查您的防火墙设置，很可能是防火墙配置导致了该问题。
• 将ChromeDriver升级到当前的ChromeDriver v2.38级别。
• 将 Chrome 版本保持在 Chrome v66.x 级别。 (as per ChromeDriver v2.38 release notes)
• 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目。
• 使用CCleaner工具可以清除执行测试套件之前和之后的所有操作系统杂务。
• 如果您的基本网络客户端版本太旧，请通过 Revo Uninstaller 卸载它并安装最新的 GA 和已发布版本的Web 客户端。
• 重新启动系统以释放端口。
• 执行您的@Test。
