问题
I am trying to make a cross domain request from my excel addin, as sugested by here : http://dev.office.com/docs/add-ins/develop/addressing-same-origin-policy-limitations
i am trying to implement a cors request. However whenever i try to open my request i get an acces denied error.
the code i use herefor try's to open a connection however here i already get the error
var xhr = new XMLHttpRequest();
xhr.open('GET', 'url'); //this line gives an acces denied error.
xhr.onload = function(e) {
}
xhr.send();
Could someone tell me if it is posible to implement a cors request within excel?
The code with ajax gives also an error object
$.ajax({
type: 'GET',
url: 'remoteurl',
cache: true,
},
success: function (result) {
functionAfterLoad(JSON.parse(JSON.stringify(eval("(" +result + ")"))));
},
error: function(result) {
console.error('Error while retrieving funnel HTML', result);
},
});
However when i do a call to :
$.ajax({
type: 'GET',
url: window.location.href ,
cache: true,
},
success: function (result) {
functionAfterLoad(JSON.parse(JSON.stringify(eval("(" +result + ")"))));
},
error: function(result) {
console.error('Error while retrieving funnel HTML', result);
},
});
I do get the html page as a result witouth any error's

HTML5 Rocks has some good tips on making CORS requests on the client-side. A lot of CORS setup is done on the server, but assuming that the server is set up to allow your request, you might just need to include xhr.withCredentials = true; before your open call.
