下面的代码我尝试使用 selenium 从 chrome 浏览器下载 PDF。

public static void main(String args[]) throws InterruptedException, AWTException, IOException, DocumentException {

    System.setProperty("webdriver.chrome.driver", "/home/sejalj/OtherProj/webDrivers/chromedriver_64");
    ChromeOptions ChromeOptions = new ChromeOptions();
    ChromeOptions.addArguments("--headless", "window-size=1024,768", "--no-sandbox");

    WebDriver driver = new ChromeDriver(ChromeOptions);

    String baseUrl = "http://url.com/";

    driver.get(baseUrl);

    driver.findElement(By.name("wl_user_name")).sendKeys("uname");
    driver.findElement(By.name("wl_user_password")).sendKeys("password");
    driver.findElement(By.cssSelector("input[value=Login]")).click();

    String pdfUrl = "https://www.pdfurl.com/displayImageDocs.php?
    f=MjAxODA3MjQxMDUwNzA4Ni5QREY=&p=aW1hZ2UuaW1hZ2ViYW5rLmJsdsaddhbmsxLjIwMTgwNy4yMDE4MDcyNA==&a=MTAwMjM0&POL_NUM=AAS06036999";";

    // Opens pdf of specific URL
    driver.get(pdfUrl);     

    Actions a = new Actions(driver);

    // To press CTRL+S
    a.keyUp(Keys.CONTROL).sendKeys("s").build().perform();

    Robot robot = new java.awt.Robot();     
    robot.keyPress(KeyEvent.VK_BACK_SPACE);     
    robot.keyRelease(KeyEvent.VK_BACK_SPACE);
    int keyInput[] = {KeyEvent.VK_A, KeyEvent.VK_A, KeyEvent.VK_A, KeyEvent.VK_A, KeyEvent.VK_UNDERSCORE,
                      KeyEvent.VK_P, KeyEvent.VK_O, KeyEvent.VK_L, KeyEvent.VK_I, KeyEvent.VK_C, KeyEvent.VK_Y
                     };

    for (int i = 0; i < keyInput.length; i++) {
          robot.keyPress(keyInput[i]);
          robot.keyRelease(keyInput[i]);
    }

    // To press ENTER
    robot.keyPress(KeyEvent.VK_ENTER);
    Thread.sleep(1000);
    robot.keyRelease(KeyEvent.VK_ENTER);

    System.out.println("Preparing Policies document...Please wait");
    System.out.println("Document prepared..");
}

上面的代码在 chrome 没有 --headless 的情况下运行时工作正常模式。但在 --headless上面的模式代码不起作用。

Robot类不支持 headless (headless)模式。请指导。

尝试这个并删除 driver.get(pdfUrl);
之后的代码 这可能会帮助您使用带有对象的字符串的 HashMap，

<-- 语言:lang-java -->

HashMap<String, Object> prefs = new HashMap<>();        
prefs.put("plugins.always_open_pdf_externally", true);
ChromeOptions.setExperimentalOption("prefs", prefs);
