在 chrome 浏览器上自动化的 selenium 代码。

chrome 版本：79.0.3945.117（本地和服务器机器相同）

chrome 驱动程序：在 chrome 版本驱动程序之前尝试了所有最新及以下版本。

执行状态 - 在本地机器上： 在无头和 gui 中工作正常。

执行状态 - 在服务器 Centros 7 机器上。 在无头中工作正常。在 GUI 中给出错误：

options.addArguments("--no-sandbox"); // Bypass OS security model
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems

分析

1- Chrome 在服务器机器上打开正常。

2-google-chrome --no-sandbox在服务器机器上使用启动 chrome

3- google-chrome 位于 /usr/bin/google-chrome 位置

因此尝试了其他答案中可用的所有步骤并使用各种 chrome 选项，但仍然无法在 chrome gui 上运行 selenium。

options.addArguments("--no-sandbox"); // Bypass OS security model
options.setBinary("/usr/bin/google-chrome");
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--test-type");
options.addArguments("--window-size=1420,1080");
options.addArguments("--disable-extensions"); //to disable browser extension popup
options.addArguments("--headless");
options.addArguments("--disable-gpu"); // applicable to windows os only
options.setExperimentalOption("useAutomationExtension", false);
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems

此处提供的答案指出 Chrome 版本 > 78 是原因。一旦我们恢复水平，问题就解决了：

此错误消息...

unknown error: Chrome failed to start: exited abnormally (unknown error: DevToolsActivePort file doesn't exist) (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

...意味着ChromeDriver无法启动/产生新的浏览上下文，即Chrome 浏览器会话。

你需要注意几件事：

  • 该参数的目的是在平台上--disable-gpu启用它是必需的，因为SwiftShader之前在无头模式下的 Windows 上的断言失败。此问题已通过Headless解决：使 --disable-gpu 标志不必要。当您在上时，您需要删除以下代码行：

    options.addArguments("--disable-gpu"); // applicable to windows os only
  • 根据您使用chrome=79.0的问题，您需要确保：

  • 当您添加ExperimentalOption时：

    options.setExperimentalOption("useAutomationExtension", false);

    • 您还需要添加ExperimentalOption：

      options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));

    • 但是您需要删除：

      options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); //to disable browser extension popup

我有这个问题。我安装了最新版本的“webdrivers”Rubygem (~> 4.2.0)。然后，在我的服务器上，我运行：

whereis google-chrome

并得到“/usr/bin/google-chrome”

我使用 ruby​​，现在可以用

options = Selenium::WebDriver::Chrome::Options.new(args: ['headless'], binary: '/usr/bin/google-chrome')
driver = Selenium::WebDriver.for(:chrome, options: options)
