WebDriver窗口调整Chrome Driver 2.28 Chrome 57的大小

Question

我已经在我的webdriver自动化中使用了set position来更改浏览器窗口大小。当我用Chrome driver 2.28运行代码时，它会抛出以下异常

**Exception starting line:**

driver.manage().window().setPosition(new Point(pos_x, pos_y));


**Trace:**

**Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: cannot get automation extension**

实际的用例是打开多个Chrome窗口，并使所有窗口都处于焦点中。现在，我无法调整窗口的大小。

最终ChromeOptions选项=新ChromeOptions（）；最终字符串adminToolURL=“http://www.google.com”；Options.AddArguments（“--disable-extensions”）；

    final WebDriver driver = new ChromeDriver(options);
    driver.manage().window().setSize(new Dimension(500, 600));

    driver.get(adminToolURL);
    driver.getWindowHandles();
    final String adminToolHandle = driver.getWindowHandle();
    int x = 0, y = 30;
    String window = "win";
    for (int i = 1; i <= 3; i++) {
        window = window + String.valueOf(i);
        System.out.println(x);
        System.out.println(y);
        ((JavascriptExecutor) driver)
        .executeScript("window.open('https://www.google.com','"
            + window + "',height=" + x + ",width=" + y + ");");
        final String handle = driver.getWindowHandle();

        driver.switchTo().window(handle.toString());
        // driver.manage().window().setPosition(new Point(pos_x, pos_y));
        pos_x = pos_x + 180;
        if ((i % 7) == 0) {
            pos_y = pos_y + 160;
            pos_x = 0;
        }
        x += 30;
        y += 40;
        Thread.sleep(2000);
        final Set<String> customerWindow = driver.getWindowHandles();
        customerWindow.removeAll(customerWindow);
        driver.switchTo().window(adminToolHandle);
    }
    Thread.sleep(600000);
    driver.quit();
}

我也遇到了这个问题。

解决方案原来非常简单--你需要用选项启动ChromeDriver。

var options = new ChromeOptions();
options.AddArgument("start-maximized");
_driver = new ChromeDriver(options);

代码在C#上。在jave上肯定是差不多的。

因此，这是一个解决办法，您可以最大化浏览器而不得到错误。
