PhantomJS: Twig_Error_Runtime？

Question

我正在学习php-phantomjs，并且正在获得一个Twig_Error_Runtime。下面是我的PHP：

    $location = '/Applications/myWebApp/js/phantomjsTest.proc';
    $serviceContainer = ServiceContainer::getInstance();

    $procedureLoader = $serviceContainer->get('procedure_loader_factory')
            ->createProcedureLoader($location);
    $client->getProcedureLoader()->addLoader($procedureLoader);

    $request = $client->getMessageFactory()->createRequest();
    $request->setType('phantomjsTest');

    $response = $client->getMessageFactory()->createResponse();
    $client->send($request, $response);

    if ($response->getStatus() === 200) {
        // Dump the requested page content
        echo $response->getContent();
    }

...and这是我的.proc文件：

phantom.onError = function (msg, trace) {
    console.log(JSON.stringify({
      "status": msg
    }));
    phantom.exit(1);
};

var system = require('system');
var uri = "http://www.jonnyw.me";

var page = require('webpage').create();
page.open(uri, function (status) {
    console.log(JSON.stringify({
      "status": status
    }));

    if (status === "success") {
        page.render('example.png');
    }
    phantom.exit(1);
});

phantom.exit(1);

我遗漏了什么？提前感谢所有人的任何信息。

Answer 1

$request->setType('phantomjsTest');

...with此命令：

$client->setProcedure('phantomjsTest');
