selenium - 无法使用 selenium webdriver 打开新 URL

Question

当尝试使用 FirefoxDriver 的 .get() 方法使用 selenium 打开新的 url 时，新的 url 没有被打开，而是出现一个空白屏幕，并出现以下异常。

我的 Firefox 版本是 27 版本“selenium-2.39.0”的 Selenium jar 在 ChromeDriver 和 IRDriver 的情况下，我遇到相同的异常

我正在使用的代码是:

    Proxy prox = new Proxy();
    prox.setAutodetect(true);

    DesiredCapabilities cap = new DesiredCapabilities();
    cap.setCapability("browser", "firefox");
    cap.setCapability(CapabilityType.PROXY,prox);
    FirefoxDriver f= new FirefoxDriver(cap);

    f.get("www.google.com");

Answer 1

请在网址前使用http前缀。将该行重写为 f.get("http://www.google.com");。这应该可行。
