如何使用硒连接到Chromium Headless [英] How to connect to Chromium Headless using Selenium
问题描述
我想将无头铬用于使用硒的自动化测试。 ( https://chromium.googlesource.com/chromium/src/ + / lkgr / headless / README.md )
I would like to use chromium headless for automated testing using selenium. (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。因此,如果我打开 http://10.252.100.33:9222/json/I 确实获得
I do have the headless version already running on 9222. So if i open http://10.252.100.33:9222/json/I do get
[ {
"description": "",

} ]
As下一步,我想将硒连接到无头铬上。但是当我尝试
As a next step I'd like to connect selenium to the headless chromium. But when i try
final DesiredCapabilities caps = DesiredCapabilities.chrome();
final WebDriver driver = new RemoteWebDriver(new URL("http://localhost:9222/json"), caps);
driver.get("http://www.google.com");
我确实得到了以下注销信息
I do get the following logout

Driver info: driver.version: RemoteWebDriver
问题是:
- RemoteWebDriver是正确的驱动程序连接到无头的
铬? - 我了解了DevTool协议( https://docs.google.com/presentation/d/1gqK9F4lGAY3TZudAtdcxzMQNEE7PcuQrGu83No3l0lw/ ),但我不确定如何使用硒创建此类客户端。
- 使用Chrome DevTools连接Chromium Headless可正常工作( https://developers.google.com/web/tools/chrome-devtools/remote-debugging/ )以及一些分段保管库;-)
- Is the RemoteWebDriver the correct driver to connect to the headless chromium?
- I read about the DevTool protocol (https://docs.google.com/presentation/d/1gqK9F4lGAY3TZudAtdcxzMQNEE7PcuQrGu83No3l0lw/), but I'm not sure, how to create such a client using selenium.
- Connecting the Chromium Headless using the Chrome DevTools works (https://developers.google.com/web/tools/chrome-devtools/remote-debugging/) besides some segmentation vaults ;-)
推荐答案
我认为自述文件是有点误导。您不必自己启动Chromium,也可以使用 RemoteWebDriver
。确保已安装chromedriver( https://sites.google.com/ a / chromium.org / chromedriver / home )。
I think the readme is a little bit misleading. You don't have to start Chromium itself and you can use the RemoteWebDriver
. Make sure that a chromedriver is installed (https://sites.google.com/a/chromium.org/chromedriver/home).
- 启动chromedriver(例如
./ chromedriver
或。 / chromedriver --port = 9515
) - 然后,您告诉chromedriver使用Chromium而不是Chrome
- 添加
-无头
作为附加参数
- Start chromedriver (e.g.
./chromedriver
or./chromedriver --port=9515
) - Then you have tell the chromedriver to use Chromium instead of Chrome
- Add
--headless
as an additional argument
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。
