java - PhantomjsDriver 不适用于 Windows 和 Linux

Question

我有一个应用程序使用 Selenium Webdriver 从站点获取一些信息。它适用于 FirefoxDriver 和 ChromeDriver，但当我尝试切换到 PhantomJSDriver 时，我遇到了一些困难。

1. 在 Windows 机器上，它正常启动，然后立即开始一遍又一遍地吐出以下行:

Jan 05, 2014 7:28:43 PM org.apache.http.impl.client.DefaultRequestDirector tryEx ecute INFO: I/O exception (org.apache.http.NoHttpResponseException) caught when processing request: The target server failed to respond

这可能会重复数百次，持续约 10 分钟，直到最终加载页面；有时它甚至根本无法加载它。

1. 在 Linux 机器上，它尝试启动，然后返回以下内容:

Exception in thread "thread1" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session.

我做错了什么？我已经阅读了很多关于 Phantomjs 为什么比其他驱动程序快得多的文章，并且真的很想使用它，但是如果加载每个页面需要 10 分钟，那显然是不可行的。

我正在运行 Selenium WebDriver 2.38.0 版和 Phantomjs 1.9.2 版。

非常感谢您，背景

编辑澄清一下，我不认为这与我的代码有任何关系； Linux 上的错误在我尝试启动 PhantomJS 驱动程序的行中抛出，如下所示。

   DesiredCapabilities caps = new DesiredCapabilities();
    caps.setJavascriptEnabled(true);                       
    caps.setCapability(
        PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
        phantombinary//"/home/p/phantomjs-1.9.2-linux-x86_64/bin/phantomjs"
    );

    // Launch driver (will take care and ownership of the phantomjs process)
     WebDriver driver = new PhantomJSDriver(caps);
    System.out.println("starting driver");

如果它在 Linux 上仍然不适合你，请尝试下面的代码，它在 Mac 上对我有用。

capabilities.setCapability("phantomjs.binary.path", "path of phantom binary/phantomjs")
