我收到错误＆＃34;代理服务器拒绝连接＆＃34;在日食

Question

你好我试过运行java代码，但它给出了错误＆＃34;代理服务器拒绝连接＆＃34;

网页未打开。我也检查了代理设置。它被设置为自动检测

仍然收到错误。我也检查了防火墙设置。所以请让我知道如何解决错误

这是代码：

＆＃13;

＆＃13;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.MarionetteDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
//import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
//import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;


public class sample_google
{

	WebDriver driver;


    @BeforeTest

    public  void setUp(){

       // FirefoxProfile profile = new FirefoxProfile();
    	System.setProperty("webdriver.gecko.driver", "D:\\ashwini\\geckodriver.exe");
    	
	  driver= new MarionetteDriver();
    	 //driver = new HtmlUnitDriver();

	    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }


    @Test

    public void testsample_google() throws Exception{

        driver.get("https://www.google.com/");
//        WebElement searchBox = driver.findElement(By.name("q"));
//        searchBox.sendKeys("fast cars");
//        searchBox.submit();
        driver.findElement(By.name("q")).sendKeys("Selenium");
        System.out.println("Page title : " + driver.getTitle());
        WebElement resultCount = driver.findElement(By.id("resultStats"));
        System.out.println("Result Count : " + resultCount.getText());
       

    }
    @AfterTest
	  public void teardown()
	  {
		  //driver.quit();
	  }

    
}

＆＃13;
