Redmine API request with Jquery, using JSONP, throws mime type error

I'm trying to send a request using Jquery using the Redmine API, which says it has support for jsonp.

So, i tried differents ways to make request with Jquery and i already search for the 'mime type' errors and try to solve using the answers but the throw error in the console is evertime the same (Google Chrome):

refused to execute script from 'http://redmine_domain_sample/users/current.json?callback=jQuery21309665620597314108_1508906065651&_=1508906065652' because its MIME type ('application/json') is not executable, and strict MIME type checking is enabled.

And in the Firefox:

SyntaxError: missing ; before statement

apponiting to the json that really returns my data. when i click i can see the data:

This is my code:

$("#redmine").click(function() { $.ajax({ type:"get", url:"http://redmine_domain_sample/users/current.json", dataType: "jsonp", contentType: "application/javascript", success: function(response) { alert(response.firstname); exibeProjetosRedmine(); } }); });

This url make an authentication request, which works, so when i input the login data, the errors on top appears.

If i make this request from an extension client , for example, the chrome Advanced REST Client, it works, but in my localhost Laravel application doesnt.

The request return 200 ok, but the Jquery request dont goes to the success function. I really even tried some solutions when i searching like:

• add some headers
• pass format=json in url

but dont work. What i'm doing wrong? I believe that is a simple error but i really not understand yet. Thanks.

Thanks all. But i solved the problem just with communication. Redmine API accepts jsonp, but this is, by default, disabled. So, i can't make request with jsonp if the domain don't allows that. No way.

Happily, i meet the redmine domain admin that i tried to access. And i asked for allows that in the administration config (docs say that) allowed jsonp. And he's made it and i solved my problem.
