jquery - Perform curl request in javascript?

Question

Is it possible to send a curl request in jQuery or javascript?

Something like this:

curl 
-H 'Authorization: Bearer 6Q************' 
'https://api.wit.ai/message?v=20140826&q='

So, in PHP on submission of a form, like this:

$header = array('Authorization: Bearer 6Q************');
$ch = curl_init("https://api.wit.ai/message?q=".urlEncode($_GET['input']));
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
curl_close($ch);

What I'm trying to do is perform this curl request, which returns json and then I plan on parsing it with jQuery's $.get() function.

curl is a command in linux (and a library in php). Curl typically makes an HTTP request.

What you really want to do is make an HTTP (or XHR) request from javascript.

Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax

Essentially you will want to call $.ajax with a few options for the header, etc.

$.ajax({
        url: 'https://api.wit.ai/message?v=20140826&q=',
        beforeSend: function(xhr) {
             xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
        }, success: function(data){
            alert(data);
            //process the JSON data etc
        }
})
