java - Chrome 驱动程序尝试在 CI 服务器中加载页面时超时，但在本地工作

Question

我的前端自动化套件在 Selenium Cucumber 中运行，不幸的是 chrome 驱动程序无法找到该元素。服务器有网络连接，我可以从 CI 服务器 ping url。

            [14:35:40][Step 1/1]       org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of Proxy element for: DefaultElementLocator 'By.id: login_email' (tried for 60 second(s) with 500 milliseconds interval)

下面是我创建 Chrome 驱动程序实例的方式。

System.setProperty("webdriver.chrome.driver",
            "browser-drivers/chromedriver");
final ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.addArguments("--no-sandbox");
    chromeOptions.addArguments("--allow-running-insecure-content");
    chromeOptions.addArguments("window-size=1920x1080");
    chromeOptions.addArguments("--disable-gpu");
    chromeOptions.addArguments("--disable-extensions");
    chromeOptions.setExperimentalOption("useAutomationExtension", false);
    chromeOptions.addArguments("--proxy-server='direct://'");
    chromeOptions.addArguments("--proxy-bypass-list=*");
    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);

    chromeDriver = new ChromeDriver(capabilities);

我在这里做错了什么？为什么它在我的而不是在服务器上工作(它也安装了 Chrome)？任何帮助将不胜感激。

更新:当它与 UI 一起运行时，它工作正常。只是 headless 是行不通的

Answer 1

貌似headless模式不支持不安全的证书，然后页面就是打不开，只打开一个空白页面，里面什么也找不到。

除了 chromeOptions 之外，只需将这两个功能添加到 DesiredCapabilities 对象:

capabilities.setCapability("acceptSslCerts", true);
capabilities.setCapability("acceptInsecureCerts", true);
