我想使用无头铬进行硒的自动化测试。 (https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md)
我确实已经在9222上运行了无头版本。所以,如果我打开http://10.252.100.33:9222/json/I,那么
[ {
"description": "",
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=127.0.0.1:9223/devtools/page/0261be06-1271-485b-bdff-48e443de7a91",

} ]
作为下一步,我想将硒连接到无头铬上。但是当我尝试
时final DesiredCapabilities caps = DesiredCapabilities.chrome();
final WebDriver driver = new RemoteWebDriver(new URL("http://localhost:9222/json"), caps);
driver.get("http://www.google.com");
我得到以下注销

我认为自述文件有点误导。您不必自己启动铬,您可以使用RemoteWebDriver。确保已安装chromedriver(https://sites.google.com/a/chromium.org/chromedriver/home)。
./chromedriver
或./chromedriver --port=9515
)代码应如下所示:
final ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setBinary("/usr/bin/chromium-browser");
chromeOptions.addArguments("--headless");
desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
WebDriver driver = new RemoteWebDriver(url, desiredCapabilities);

或者,如果您在本地运行它,您可以这样做。在斯卡拉。
val chromeOptions = new ChromeOptions
chromeOptions.addArguments("--headless")
new ChromeDriver(chromeOptions)

如果您使用的是selenium 3+ chrome驱动程序,则只需使用chrome选项并启动驱动程序即可。检查项目中的详细信息
Example Project on Chrome Headless running with different options
options.setHeadless(true)
答案 3 :(得分:1)
*使用以下代码:
ChromeOptions options = new ChromeOptions();
options.setHeadless(true); //Set Chrome option
driver = new ChromeDriver(options);
您将获得“ Headless” Chrome!
*完整代码
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions; //import ChromeOptions
public class web_crawl {
private static WebDriver driver = null;
public static void main(String[] args) {
ChromeOptions options = new ChromeOptions();
options.setHeadless(true);
driver = new ChromeDriver(options);
driver.get("http://www.google.com"); //The website you want to connect to
}

Chrome 59能够将实例创建为无头。我尝试过使用新的Chrome驱动程序2.30的Windows,它对我有用 https://www.automation99.com/2017/07/how-to-use-chrome-headless-using.html?m=1
