Question

我用C编写了一个网络ICMP ping代码，以下是我的代码，它试图ping上千个IP，但是运行几天后，打开套接字的总数增加到35K。我应该在哪里释放插座。

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.events.AbstractWebDriverEventListener;
import org.openqa.selenium.support.events.EventFiringWebDriver;

public class HighLighterEventListener extends AbstractWebDriverEventListener {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "./libs/chromedriver 4");
        WebDriver webdriver=new ChromeDriver();

        EventFiringWebDriver driver = new EventFiringWebDriver(webdriver);
        webdriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.get("https://yosuva.com");
        driver.register(new HighLighterEventListener());

        driver.findElement(By.xpath("//span[text()='Home']"));
        driver.findElement(By.xpath("//span[text()='About']"));
        driver.findElement(By.xpath("//span[text()='Tools']"));
        driver.findElement(By.xpath("//span[text()='News']"));
        driver.findElement(By.xpath("//span[text()='Events']"));
        driver.findElement(By.xpath("//span[text()='Contact']"));

        driver.quit();
    }

    @Override
    public void afterFindBy(By by, WebElement element, WebDriver driver) {
        ((JavascriptExecutor)driver).executeScript(
            "arguments[0].style.border='3px solid green'",element
        );
    }
}

您应该在函数结束时关闭套接字。在for循环之后。

我的代码是否导致太多套接字未释放
