selenium - 水貂 + PhantomJS : How do I set the user agent?

Question

我将 phantomjs 与 mink 一起使用:

default:
  extensions:
    Behat\MinkExtension\Extension:
      goutte: ~
      selenium2:
        browser: phantomjs
        wd_host: http://localhost:8643/wd/hub
        capabilities:
           webStorageEnabled: true

但我需要伪装成最新的 chrome。我试过这个:

    /**
     * @BeforeStep
     */
    public function masqueradeAsLatestChrome(StepEvent $event)
    {
        $this->getSession()->setRequestHeader('User-Agent', 'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2049.0 Safari/537.36');
    }

但我得到了异常(exception):

[Behat\Mink\Exception\UnsupportedDriverActionException]                                                
Exception has been thrown in "beforeStep" hook, defined in FeatureContext::masqueradeAsLatestChrome()  
Request header is not supported by Behat\Mink\Driver\Selenium2Driver

chrome 的版本并不重要，但网络应用程序必须认为它正在与最新版本的 chrome 对话。

Selenium does not provide this capability, as it is not something a user can do. It's recommended you use a proxy to inject additional headers to the requests generated by the browser.

遗憾的是......然而，PhantomJS 确实提供了一个 interface for setting the headers .最好的办法是使用它的 REST API 向它发送直接命令。还有一个很酷的 PHP wrap library这将使它变得容易 200 倍。
