Chrome 无法访问 Selenium WebDriver 错误 [英] Chrome not reachable Selenium WebDriver error

问题描述

我正面临这个问题；我知道这个问题已经存在，我已经尝试了提到的解决方案，因此用我的配置和代码询问这个问题.

I am facing this issue; I know this question is already present and I have tried the solutions mentioned hence asking this with my configurations and code.

早期脚本正在运行，但现在它们没有运行所以我尝试制作一个基本的打开浏览器脚本.

Earlier the scripts were running but now they aren't So i tried making a basic open browser script.

Selenium WebDriver 的最新版本:http://selenium-release.storage.googleapis.com/3.5/selenium-java-3.5.0.zip

Latest Version of Selenium WebDriver : http://selenium-release.storage.googleapis.com/3.5/selenium-java-3.5.0.zip

ChromeDriver 的最新版本:http://chromedriver.storage.googleapis.com/index.html?path=2.31/

Latest Version on ChromeDriver : http://chromedriver.storage.googleapis.com/index.html?path=2.31/

基本打开浏览器代码:

package Trial;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Trial_Class {
    public static void main(String args[]){
        System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.get("http://www.youtube.com");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

    }
}

但我仍然收到以下错误:

But still I am getting the below error:

提前致谢.

推荐答案

我发现 chromedriver 很难解析 localhost 并在此期间打印出来

I found that chromedriver had hard time to resolve localhost and during that it printed

Timed out connecting to Chrome, retrying...

它首先尝试通过 ipv6 连接，然后我猜想回退到 ipv4.所以对我有用的是以这种方式更改本地主机"的优先级

It first tried to connect via ipv6 and then I guess fall back to ipv4. So what worked for me was to change the priority of "localhosts" this way

您唯一需要做的就是更改优先级:

The only piece you should need to do is change the priority:

打开 RegEdit，导航到HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices cpip6Parameters创建 DisabledComponents DWORD 注册表值，将其值设置为 20(十六进制).src

Open RegEdit, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices cpip6Parameters Create DisabledComponents DWORD registry value, set its value to 20 (Hexadecimal). src
