使用 geckodriver 时遇到 HttpHostConnectException

Question

我刚开始在我的办公室设置自动化 硒的帮助，但仅在初始水平上受到打击。我用了一个 基本代码最初只是为了检查浏览器是否工作和处理 代码进一步但遇到了问题。

import java.io.IOException;
import java.net.InetAddress;
import java.util.concurrent.TimeUnit;

import org.apache.http.conn.HttpHostConnectException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

public class ABC {




public static void main(String[] args) 
{

    System.setProperty("webdriver.gecko.driver","C:\\Users\\12345678\\
    AppData\\Local\\Mozilla Firefox\\firefox.exe");

    DesiredCapabilities dc=DesiredCapabilities.firefox();
    FirefoxProfile profile = new FirefoxProfile();
    dc.setCapability(FirefoxDriver.PROFILE, profile);
    WebDriver driver =  new FirefoxDriver(dc);
    driver.get("http://www.google.com");
    driver.manage().timeouts().implicitlyWait(10L, TimeUnit.SECONDS);

}`

Answer 1

您的代码看起来不错，但有几点：

1. 要使用 Selenium 3.x 和 Mozila Firefox 52.x，您需要从 this location 下载最新的 gecko 驱动程序并保存。

2. 您需要提供“geckodriver.exe”的绝对路径，而不是“firefox.exe”

替换：

System.setProperty("webdriver.gecko.driver","C:\\Users\\12345678\\
    AppData\\Local\\Mozilla Firefox\\firefox.exe");

作者：

System.setProperty("webdriver.gecko.driver","C:\\your_directory\\geckodriver.exe");

1. 最后你的代码看起来像：

   System.setProperty("webdriver.gecko.driver", "C:\\SeleniumUtilities\\BrowserDrivers\\geckodriver.exe");
   DesiredCapabilities dc = DesiredCapabilities.firefox();
   FirefoxProfile profile = new FirefoxProfile();
   dc.setCapability(FirefoxDriver.PROFILE, profile);
   WebDriver driver =  new FirefoxDriver(dc);
   driver.manage().window().maximize();
   driver.get("http:\\gmail.com");
   

这段代码对我来说执行得很好。

如果这对你有帮助，请告诉我。
