Get environment inside controller

问题

I have a situation in one of my controllers that should only be accessed via AJAX, I have the following code.

if (!$request->isXmlHttpRequest()) {
    $response = new Response();
    $response->setContent('AJAX requests only!');
    return $response;
}

When I am testing this gives me an issue because the request hasn't actually been made via AJAX. This then breaks my tests every time. How should I go about working around this?

My Ideas:

I have tried to set a server header but have had absolutely no success.
Check if I am in the test environment in the controller and don't do the check if it is. I know this is dirty, but it would work. :-/ The problem was that I couldn't figure out how to discover what environment I am in.

Anyone else have any other ideas or tips that I am missing to get one of the above to work?

回答1:

Looking at the code for isXmlHttpRequest in class Request and method getHeaders in class ServerBag, the piece of code below should do the trick:

$client->request(
    'GET',
    '/path/to/test',
    array(),
    array(),
    array(
        'HTTP_X-Requested-With' => 'XMLHttpRequest',
    )
);

I did not test it personally but I think it should works. The line of code below in Request is used to check if the http request is a XmlHttpRequest.

return 'XMLHttpRequest' == $this->headers->get('X-Requested-With');

In the code, $this->headers is set using:

$this->headers = new HeaderBag($this->server->getHeaders());

The method getHeaders creates an array of headers. Each server variable starting with HTTP_, plus some special server variables like CONTENT_TYPE, are put in this array.

Hope this helps.

Of course in Icode4food's case, it's better to use Matt's solution, but here is how to find the current environment:

$this->container->getParameter(‘kernel.environment’)
