Chrome不可达Selenium WebDriver错误

Question

我正在面临这个问题；我知道这个问题已经存在，并且我已经尝试了提到的解决方案，因此在我的配置和代码下询问。

之前脚本是可以运行的，但现在不行了。所以我尝试制作一个基本的打开浏览器的脚本。

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/

基本的打开浏览器代码：

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);

    }
}

但是我仍然收到以下错误：

 Starting ChromeDriver 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8) on port 43967

请更新您的Chrome浏览器版本。 - Guy

Answer 1

您的chromedriver已启动正常：

"Starting ChromeDriver 2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8) on port 43967"

问题在于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，请将以下代码添加到您的代码中：

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) 您的浏览器已经是最新版本，但您的chromedriver不是 - 当前版本为2.33

Answer 2

我发现chromedriver很难解析localhost，在此期间它会输出。

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。所以对我有用的是改变“本地主机”的优先级，方法如下：

只需更改优先级即可：打开RegEdit，导航到HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters，创建DisabledComponents DWORD注册表值，将其值设置为20（十六进制）。src

Answer 3

你必须设置

setProperty(String key, String path) 

这里的"key"是你的"webdriver.chrome.driver"，而"path"则是你的驱动程序存储路径。在路径中使用单个正斜杠"/"。

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);

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