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
}
})
Yes, use getJSONP. It's the only way to make cross domain/server async calls. (*Or it will be in the near future). Something like
$.getJSON('your-api-url/validate.php?'+$(this).serialize+'callback=?', function(data){
if(data)console.log(data);
});
The callback parameter will be filled in automatically by the browser, so don't worry.
On the server side ('validate.php') you would have something like this
<?php
if(isset($_GET))
{
//if condition is met
echo $_GET['callback'] . '(' . "{'message' : 'success', 'userID':'69', 'serial' : 'XYZ99UAUGDVD&orwhatever'}". ')';
}
else echo json_encode(array('error'=>'failed'));
?>
You can use JavaScripts Fetch API (available in your browser) to make network requests.
If using node, you will need to install the node-fetch package.
const url = "https://api.wit.ai/message?v=20140826&q=";
const options = {
headers: {
Authorization: "Bearer 6Q************"
}
};
fetch(url, options)
.then( res => res.json() )
.then( data => console.log(data) );
