java在linux服务器上执行chromedriver

Question

我正在使用 Eclipse、Selenium 和 chromedriver 来促进网站数据的 headless 检索。虽然我在笔记本电脑上运行良好，但我已经将 WAR 版本部署到 Java/Linux 托管服务并收到以下错误，表明它找不到 chromedriver。

类型异常报告

留言:

The driver executable does not exist: /drivers/chromedriver

描述:

The server encountered an unexpected condition that prevented it from fulfilling the request.

异常:

最初我有 windows 位置 C:\java\selenium\drivers\chromedriver.exe

但是我上传了Linux版本，放在"/drivers/chromedriver"

部分代码看起来像这样......

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    String carRegistrationNumer = request.getParameter("cargo");

    System.setProperty("webdriver.chrome.driver",
            "/drivers/chromedriver");

    ChromeOptions options = new ChromeOptions();
       options.addArguments("headless");
       options.addArguments("window-size=1200x600");

    WebDriver webDriver = new ChromeDriver(options);

是的，我已经将文件夹和 chromedriver 的权限设置为 777 (chmod 777)，所以应该没问题 - 只是找不到它。

请帮忙...

当您在 Linux 平台上以 headless 模式使用 chromedriver 时，您应该使用以下选项:

System.setProperty("webdriver.chrome.driver", "/drivers/chromedriver");
ChromeOptions options = new ChromeOptions();
options.addArguments("headless");
options.addArguments("--disable-gpu");
options.addArguments("disable-infobars");
options.addArguments("--disable-extensions");
options.addArguments("window-size=1200x600");
options.addArguments("--no-sandbox");
WebDriver webDriver = new ChromeDriver(options);

Note : If you are using chromedriver in headless mode on Linux platform the argument disable-gpu is crucial and mandatory. See Getting Started with Headless Chrome
