Java.NET中出现异常：调用driver.quit()时连接复位;

我看到了这些线索：
java.net.SocketException: Connection reset on Selenium driver.close() or driver.quit() statements
selenium/java- java.net.SocketException: Connection reset
但我还是不明白这里的问题。一切都很好，我从网站上得到了响应和内容，当我完成时，我调用driver.quit();/driver.close();并得到了异常。如果我不调用.quit();，我就得不到异常。
我得到这个异常后，我得到了网页抓取内容：

这是从主代码：

String url = "https://relatedwords.org/relatedto/";
        System.setProperty("webdriver.chrome.driver", filePath);

        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--headless");

        WebDriver driver = new ChromeDriver(chromeOptions);
        driver.get(url + "Fishsticks");

        WebElement words = driver.findElement(By.className("words"));
        final List<WebElement> wordList = words.findElements(By.tagName("a"));
        wordList.forEach(word -> System.out.println(word.getText()));

        // when I remove this I do not get any exceptions
        driver.quit();

我使用的是刚刚检查的最新chrome版本，没有可用的更新（版本109.0.5414.120），我使用的是chrome驱动程序版本ChromeDriver 109.0.5414.74和最新的selenium版本4.8.0
那么这里的解决方案是什么呢？我尝试读取这么多堆栈线程，但没有找到任何解决方案

下面是我试过的相同代码，它工作正常，没有例外。唯一的区别是我没有添加下面的代码System.setProperty("webdriver.chrome.driver", filePath);。当您使用最新版本的selenium（无论如何，您都在使用）时，您不需要设置属性。请尝试删除此行，看看它是否解决了您的问题。

public static void main(String[] args){
    
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless");

    WebDriver driver = new ChromeDriver(options);
    driver.get("https://relatedwords.org/relatedto/" + "Fishsticks");
    
    WebElement words = driver.findElement(By.className("words"));
    final List<WebElement> wordList = words.findElements(By.tagName("a"));
    wordList.forEach(word -> System.out.println(word.getText()));

    driver.quit();

}

以下是控制台输出：

java. net套接字异常：连接复位

java.net.SocketException可能由于以下几个可能的原因而发生：

  • 当客户端在通过套接字返回响应之前关闭套接字连接时，可能会在服务器端发生这种情况。例如，在检索响应之前退出浏览器。
  • 如果写入另一端已正常关闭的连接，也会发生这种情况，从而导致应用程序协议错误。

此用例

我把你的程序执行了一下，结果如下：

  • 代码块：
System.setProperty("webdriver.chrome.driver", "C:\\BrowserDrivers\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(options);
driver.get("https://relatedwords.org/relatedto/Fishsticks");
WebElement words = driver.findElement(By.className("words"));
final List<WebElement> wordList = words.findElements(By.tagName("a"));
wordList.forEach(word -> System.out.println(word.getText()));
driver.quit();
  • 控制台输出：

结论

从程序上看，我没有看到你的代码块中有任何错误。但是请确保：
