Cross-Domain error when using the API with Ajax

Posted (edited) · Cross-Domain error when using the API with Ajax

Hi,

I'm currently trying to use the API to control remotely my Ultimaker 3 with a webpage.

So, I use Ajax to make a request on the printer but it won't allow me to make the request.

For the moment I try to check the validity of the id :

function checkTicket(ticketId) {
            $.ajax({
                    type: 'GET',
                    url: 'http://192.168.1.120/api/v1/auth/check/' + ticketId,
                    contentType: 'application/json',
                    headers: {
                        'Accept': 'application/json'
                    }
                }
            ).done(function (data, textStatus, jqXHR) {
                console.log(data);
                switch (data.message) {
                    case "authorized":
                        break;
                    default:
                        requestTicket(user.name);
                        break;
                }
            }).fail(function (jqXHR, textStatus, errorThrown) {
                console.log(jqXHR);
            });

But I got an error :

Failed to load http://192.168.1.120/api/v1/auth/check/c6c71b01f5b5292c6261632ae2xxxxxx: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1' is therefore not allowed access.

 

My request headers :

Thanks for your help !
