标签: java selenium chromium headless

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",
   "id": "0261be06-1271-485b-bdff-48e443de7a91",
   "title": "The Chromium Projects",
   "type": "page",
   "url": "https://www.chromium.org/",
   "webSocketDebuggerUrl": "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

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)。

  • 启动chromedriver(例如./chromedriver./chromedriver --port=9515
  • 然后你告诉chromedriver使用铬代替铬
  • 添加" - 无头"作为附加论点

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);

在Ubuntu Linux上为我工作。

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)

*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
