带有jquery ajax的POST请求

Question

llo i am using box api to for integration they have given just curl to get access token which is as follow

is curl https://www.box.com/api/oauth2/token \
-d 'grant_type=authorization_code&code={your_code}&client_id={your_client_id}&client_secret={your_client_secret}' \
-X POST

I want to get access token using jquery ajax request i have tired my code like this as follow :

var data2= '{"grant_type":"authorization_code", "client_id":"61oliuyi1jckqos0j8zzl9h4t791umux" ,"client_secret":"Oi1XS56al61oOrrvAL3i5gdPTfe7QO9V" ,"code" :"'+code+'"}';
var data1 = JSON.parse(data2);

$.ajax({
                    type: 'POST',
                    url:  "https://www.box.com/api/oauth2/token",
                    data: data1,
                    success: function(json) {
                        console.log(e);
                       alert("success"+json);
                    },
                    error: function(e) {
                        console.log(e)
                        alert("Failure"+ JSON.stringify(e));

                    }
                });

MLHttpRequest cannot load https://www.box.com/api/oauth2/token. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.

The problem is simply due to cross-domain request. The Javascript Origin Policy is going to prevent you from making Ajax request to the API from another domain (like localhost, which you are using). Nice explanation of the error here.

As you are trying to use Box.com API, you should use YQL to make your code working. This dev article from their blog shows exactly how to integrate YQL, and seems to be the best option.
