Chrome无法访问Selenium WebDriver错误

Question

我面临着这个问题；我知道这个问题已经出现了，我已经尝试了上面提到的解决方案，因此用我的配置和代码问了这个问题。

之前的脚本正在运行，但现在没有，所以我试着制作一个基本的开放浏览器脚本。

Selenium WebDriver的最新版本：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/

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);

    }
}

但我还是得到了以下错误：

 Starting ChromeDriver 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8) on port 43967

提前谢谢。

Answer 1

你必须设定

setProperty(String key, String path) 

这里的“key”是您的“webdriver.chrome.driver”，“path”是“存储驱动程序的路径”。在路径中使用单正斜杠“/”。

System.setProperty("webdriver.chrome.driver", "E:/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);

以上代码在Selenium jar 3.5.0中运行良好。希望在您的系统中也能正常工作。

Answer 2

我发现Chrome驱动程序很难解决localhost在此期间它打印

Timed out connecting to Chrome, retrying...

它首先试图通过ipv6连接，然后我想回到ipv4。所以对我来说有效的是以这种方式改变“localhost”的优先级

你需要做的唯一一件事就是改变优先级：

打开RegEdit，导航到HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters Create DisabledComponents DWORD注册表值，将其值设置为20（十六进制）。src

Answer 3

你的chromedriver刚刚起步：

“在端口43967上启动ChromeDriver 2.31.488763（092de99f48a300323ecf8c2a4e2e7cab51de5ba8）”

问题是浏览器本身没有响应。所以我有两个想法：

1）您的浏览器未安装在默认位置；如果是这种情况，请将此添加到您的代码中：

ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/other/chrome/binary");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
WebDriver driver = new ChromeDriver(capabilities);

2） 你的浏览器是最新版本，但你的chromedriver不是——当前版本是2.33
