java - ChromeDriver 需要安装 Chrome 吗？

Question

我有以下代码:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
webDriver = new ChromeDriver(chromeOptions);

它抛出异常:

Gtk-Message: Failed to load module "topmenu-gtk-module"
Created new window in existing browser session.
Exception in thread "main" org.openqa.selenium.WebDriverException:
Timed out waiting for driver server to start.

Build info: version: '3.4.0', revision: 'unknown', time: 'unknown'
System info: host: 'luis', ip: '127.0.1.1', os.name: 'Linux',     os.arch: 'amd64', os.version: '4.4.0-87-generic', java.version:     '1.8.0_112'
Driver info: driver.version: ChromeDriver
at org.openqa.selenium.remote.service.DriverService.waitUntilAvailable(DriverService.java:193)
at org.openqa.selenium.remote.service.DriverService.start(DriverService.java:181)
at org.openqa.selenium.remote.service.DriverCommandExecutor.execute(DriverCommandExecutor.java:78)

我是新手，我错过了什么吗？我的主机上应该运行任何其他服务器吗？

首先，如果您想使用 Chrome，那么您需要从以下 URL 下载它的二进制文件:-

https://sites.google.com/a/chromium.org/chromedriver/

现在在驱动程序实例之前添加System.setProperty

System.setProperty("webdriver.chrome.driver","D:\\Workspace\\JmeterWebdriverProject\\src\\lib\\chromedriver.exe");
WebDriver driver = new ChromeDriver(); 

现在如果你想使用 headless 那就使用 phantomjs。这是一个稳定的构建，您可以将其用于 headless 工作。从下面的链接下载:-

http://phantomjs.org/download.html

现在在驱动程序实例之前添加System.setProperty

DesiredCapabilities caps = new DesiredCapabilities();
caps.setJavascriptEnabled(true); // not really needed: JS enabled by default
caps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "C:/phantomjs.exe");
WebDriver driver = new PhantomJSDriver(caps);
