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);
     }}

但是得到错误：

拿起_JAVA_OPTIONS：-Djava.net.preferIPv4Stack = true

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 OS Unix进程无法绑定到系统中指定的空闲端口。

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`“无效端口。退出...” 。

但是，根据讨论的历史：

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

有人观察到，当通过网络共享 ChromeDriver 和 GeckoDriver 时，在初始化浏览器客户端时会发现以下错误：

样本A：

Starting ChromeDriver 2.28.455520 (cc17746adff54984afff480136733114c6b3704b) on port 12121

甚至：

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，查看是否已达到可能的打开连接限制，或检查给定端口上是否有其他应用程序在运行。
检查防火墙设置，防火墙配置很可能导致问题。
将 ChromeDriver 升级到当前ChromeDriver v2.38级别。
将 Chrome 版本保留在 Chrome v66.x 级别。（as per ChromeDriver v2.38 release notes）
通过 IDE 清理您的项目工作区，仅使用所需的依赖项重建项目

。
使用CCleaner工具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 Web客户端版本太旧，请通过Revo Uninstaller将其卸载并安装最新的GA和已发布的 Web客户端版本。

执行系统重新启动以释放端口。

执行@Test。

CreatePlatformSocket（）返回错误：提供了无效的参数。端口不可用。在Chrome上运行selenium代码时退出...
