使用最近的selenium服务器（2.41）无法在Firefox中打开url

Question

我一直使用Selenium Server 2.32和Firefox 24.4（在CentOS 5上）运行单元测试 - 刚刚更新了Firefox，并转移到Selenium 2.41，现在Selenium不会打开URL。我假设在我需要适应的Firefox或Selenium中发生了一些变化，但无法弄清楚是什么。

我尽可能地创建了一个干净的测试程序，紧随其后。它的工作原理（在Firefox窗口中打开google.com）使用Selenium 2.32，但不在Selenium 2.41中。从查看Selenium输出中我可以看出它是404错误，但不知道。

感谢任何帮助！

php中的测试用例：

$seleniumUrl  = "http://mydomain.com:4444/wd/hub";
$desired_capabilities = array('browserName' => 'firefox');
$results = mycurl(
      $seleniumUrl,
      'POST',
      '/session',
      array('desiredCapabilities' => $desired_capabilities),
      array(CURLOPT_FOLLOWLOCATION => true));

$seleniumUrl = $results['info']['url'];

$goToUrl = "http://google.com";
mycurl($seleniumUrl, 'POST', '/url', array('url' => $goToUrl));

以下是mycurl函数的来源：

function mycurl(
    $seleniumUrl,
    $http_method,
    $command,
    $params = null,
    $extra_opts = array()) {

    if ($params && is_array($params) && $http_method !== 'POST') {
      throw new Exception(sprintf(
        'The http method called for %s is %s but it has to be POST' .
        ' if you want to pass the JSON params %s',
        $command,
        $http_method,
        json_encode($params)));
    }

    $url = sprintf('%s%s', $seleniumUrl, $command);
    if ($params && (is_int($params) || is_string($params))) {
        $url .= '/' . $params;
    }

    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt(
       $curl,
       CURLOPT_HTTPHEADER,
       array(
         'Content-Type: application/json;charset=UTF-8',
         'Accept: application/json'));

    if ($http_method === 'POST') {
      curl_setopt($curl, CURLOPT_POST, true);
      if ($params && is_array($params)) {
        curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($params));
      }
    } else if ($http_method == 'DELETE') {
        curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'DELETE');
    }
    foreach ($extra_opts as $option => $value) {
         curl_setopt($curl, $option, $value);
    }
    $raw_results = trim(curl_exec($curl));
    $info = curl_getinfo($curl);

    if ($error = curl_error($curl)) {
       $msg = sprintf(
             'Curl error thrown for http %s to %s',
             $http_method,
             $url);
       if ($params && is_array($params)) {
           $msg .= sprintf(' with params: %s', json_encode($params));
       }
       throw new Exception($msg . "\n\n" . $error);
    }
    curl_close($curl);

    $results = json_decode($raw_results, true);

    $value = null;
    if (is_array($results) && array_key_exists('value', $results)) {
       $value = $results['value'];
    }

    $message = null;
    if (is_array($value) && array_key_exists('message', $value)) {
       $message = $value['message'];
     }

     return array('value' => $value, 'info' => $info);
  }
