当从QueryPath访问OpenAmplify时，我的HTTP请求失败/超时。为什么？

Question

WHen我在WAMP上从cmd.exe命令行运行这个脚本，我得到：

 Could not retrieve data from OpenAmplify.file_get_contents(http://portal
tnx.openamplify.com/AmplifyWeb/AmplifyThis?apiKey=MY_API_KEY_GOES_HERE): failed to open stream: HTTP request failed!  (C:\wamp\www\Learning_Query_Pa
th\src\QueryPath\QueryPath.php: 4053)

当我通过firefox浏览器v19.0从localhost运行这个脚本时，我得到：

Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\Learning_Query_Path\src\QueryPath\QueryPath.php on line 4525

下面是我使用的脚本：

    <?php

require 'src/QueryPath/QueryPath.php';

$url = 'http://portaltnx.openamplify.com/AmplifyWeb/AmplifyThis?';
$key = 'I_PUT_MY_API_KEY_HERE';
$text = 'I_PUT_TEXT_HERE';

$params = array(
  'apiKey' => $key,
);

$url .= http_build_query($params);

$options = array(
  'http' => array(
    'method' => 'POST',
    'user_agent' => 'QueryPath/2.0',
    'header'  => 'Content-type: application/x-www-form-url-encoded',
    'content' => http_build_query(array('inputText' => $text)),
  ),
);

$context = stream_context_create($options);
try {
  $qp = qp($url, NULL, array('context' => $context));
}
catch (Exception $e) {
  print "Could not retrieve data from OpenAmplify." . $e->getMessage();
  exit;
}

    $qp->find('ProperNouns>TopicResult>Topic>Name')->slice(0, 20);


$out = qp(QueryPath::HTML_STUB, 'body')->append('<ul/>')->find('ul');


foreach ($qp as $name) {
  $out->append('<li>' . $name->text() . '</li>');
}

$out->writeHTML();


?>

我怎么才能让它工作呢？

附注: Open Amplify是一个web服务，它接受所提供的文本，并在分析它之后，返回关于它的许多有趣的事情。我真的很热衷于让这项工作成为QueryPath的忠实粉丝，所以我只对如何让它与QueryPath一起工作的建议感兴趣！

尝试点击此url。这应该可以工作，http://portaltnx20.openamplify.com/AmplifyWeb_v21/AmplifyThis
