如何使用Selenium连接到Chromium Headless

selenium

我想将无头铬用于使用selenium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。因此，如果我打开http://10.252.100.33:9222/json/，我会得到

[ {
   "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"
} ]

下一步，我想将selenium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");

我确实得到以下注销

我认为自述文件有点误导。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）。

  • 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--headless为附加参数

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。
