Selenium Chrome 浏览器 org.openqa.selenium.WebDriverException:等待驱动程序服务器启动超时 [英] Selenium Chrome Browser org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start

问题描述

公共类 Dem {public static void main(String[] args) 抛出 InterruptedException {WebDriver 驱动程序；String url = "https://www.google.com";System.setProperty("webdriver.chrome.driver","C:\Users\Jim\Downloads\chromedriver_win32\chromedriver.exe");驱动程序 = 新的 ChromeDriver();driver.get(url);驱动程序关闭()；}}

Selenium webdriver 和 Chrome 驱动程序是最新版本

硒网络驱动程序:3.14.0

铬驱动程序:2.42

java:1.8.0_181

这是运行代码后的错误.谷歌浏览器根本无法启动.

如果您没有收到以上消息并且您的服务器没有启动，请检查您收到的错误是什么并相应地做出响应?可能下载了损坏的二进制文件，重新下载.

2.无法访问主机名为 localhost

的 chrome 驱动程序

如果您能够按照上述步骤成功启动 chromedriver，现在尝试使用相应端口访问以下 url.http://localhost:{port}/status

例如，在上面的消息中，服务器在端口 9515 上启动.在浏览器中访问 url，http://localhost:9515/status

你应该得到上面的消息，表明可以使用主机名访问服务器 localhost

如果您无法访问，请使用管理员权限在编辑器中打开 C:WindowsSystem32driversetchosts 并检查 localhost DNS 已映射到 127.0.0.1

public class Dem {
    public static void main(String[] args) throws InterruptedException {
    WebDriver driver;
    String url = "https://www.google.com";
    System.setProperty("webdriver.chrome.driver","C:\Users\Jim\Downloads\chromedriver_win32\chromedriver.exe");
    driver = new ChromeDriver();
    driver.get(url);
    driver.close();
    }
}

Selenium webdriver and Chrome driver are the latest versions

Selenium webdriver :3.14.0

chromedriver: 2.42

java:1.8.0_181

And this is the error after running the code. Google chrome doesn't launch at all.

解决方案

Debugging Steps

It may be either of the two below issue.

1. Chrome Driver not started for some reason:

Run the chrome driver in terminal maually

C:UsersJim> C:UsersJimDownloadschromedriver_win32chromedriver.exe

Now we have to get the following message denoting server started sucessfully.

If you are not getting above message and your server is not started, then check what is error you are getting and respond accorsingly? May downloaded corrupted binary, the download it again.

2. Unable to access the chrome driver with hostname as localhost

If you able to start chromedriver sucessfully as in above steps, now try to access the below url with respective port. http://localhost:{port}/status

For e.g., in above message, the server started on port 9515. Access the url in browser, http://localhost:9515/status

You should get above message indicating server is accessible with hostname as localhost

If your are not able access, then open C:WindowsSystem32driversetchosts in editor with administrator privilege and check localhost DNS is mapped to 127.0.0.1
