SharePoint 2013 API jQuery.Ajax Access Denied

Question

I am trying something simple - to retrieve list information from a SharePoint 2013 list. However, I am getting access denied when the jQuery Ajax is processed. I've tried setting up headers with the headers object and the beforeSend function, but with no success. Here is my jQuery.Ajax:

$.ajax({
        headers: { // also tried with Authentication
            "Authorization": someBasicCryptedCred,
            "Accept": "application/json; odata=verbose"
        },
        url: "http://spSiteCollection/_api/web/lists/getbytitle('MyList')/items",
        type: "GET",
        success: SuccessProcess,
        error: ErrorProcess
    });

My application is a simple MVC Mobile app

I am following these documentation (along with some other from MSDN but cannot post more than 2 links):

Answer 1

Maybe you need the Form Digest Value, you can get with jQuery with

$('#__REQUESTDIGEST').val();

You can get with api rest call, with /_api/ContextInfo and that retrieve a JSON object with other many fields apart of Form Digest Value.

http://<site url>/_api/contextinfo

I don't see the Form Digest value in the call, could that be the reason?

X-RequestDigest = form digest value

Basically what you are doing, is looks like you are accessing cross site collection data from you app web, so please provide proper permission to your app through file. 文件为您的应用程序提供适当的权限。 thats it and you are done.
