我正在制作一个 java selenium 机器人，当我启动机器人时，它说在代码的最后一行之后连接重置

我得到这个错误，即使我的

• Chrome 版本 = 96
• 驱动程序版本 = 96

请帮忙

代码如下:

public static void main(String[] args) throws InterruptedException {
        //region GUI
        int loginTimeOutDuration = 100000;
        int chatLoadingDelay = 1000;
        String serverID = "707324806856572949";
        String message = "Hi!";
        //endregion

        System.setProperty
                ("webdriver.chrome.driver","C:\\\\Users\\\\~~~~~\\\\Downloads\\\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();

        String baseUrl = "https://discord.com/channels/" + serverID + "/";

        driver.get(baseUrl);
        Thread.sleep(loginTimeOutDuration);
        WebElement element = driver.findElement(By.xpath("/html/body/div[1]/div[2]/div/div[2]/div/div/div/" +
                "div/div[2]/div[2]/div/aside/div/div/div[2]/div/div[2]/div[1]"));

        Actions actions = new Actions(driver);
        actions.contextClick(element).perform();
        driver.findElement(By.xpath("/html/body/div[1]/div[5]/div/div/div/div[1]/div[2]")).click();

        driver.close();
    }

...暗示 ChromeDriver 无法启动/生成新的浏览上下文，即 Chrome 浏览器 session 和 java.net.SocketException:连接重置发生。

您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示:

• 尽管您使用的是 chromedriver=96.0
• 可能您正在使用 Selenium v4.0.0其中:

• Supported CDP versions: 85, 93, 94, 95

因此，您会看到:

WARNING: Unable to find an exact match for CDP version 96, so returning the closest version found: 95

---

解决方案

确保:

• Selenium 升级到当前v4.1.0其中:

• Supported CDP versions: 85, 94, 95, 96
