Connection to SharePoint APIs using Hybrid Mobile application

Connection to SharePoint APIs using Hybrid Mobile application

I am working on a mobile hybrid application, where am trying to connect to
a sharepoint website using apis it provide. Basically I want to connect
and access some sharepoint data. After so much of googling I am atlast
able to login to Office 365 using below piece of code.
$.ajax({
'url': 'https://login.microsoftonline.com/extSTS.srf',
dataType: 'text',
type:'POST',
'data': '<s:Envelope

headers: {
Accept : "application/soap+xml; charset=utf-8"
},
success: function(result, textStatus, jqXHR) {
document.body.innerHTML = result;
var xmlDoc = $.parseXML( result );
var xml = $( xmlDoc )
var binToken = xml.find("BinarySecurityToken").text();
callsomeFunction(binToken);
},
error:function (jqXHR, textStatus, errorThrown){
console.log(errorThrown+'error login:' + jqXHR.responseText);
},
complete:function(jqXHR, textStatus) {
console.log('login completed ' + textStatus);
}
});
Now I have a binToken (which I am getting successfully) and I am using it
to call an api, as this,
function callsomeFunction(binToken) {
var domain = "myurlishere";
var url = domain + "_api/web/GetFolderByServerRelativeUrl('PDF')";
$.support.cors = true;
$.ajax({
'url': url,
dataType: 'text',
type:'POST',
'data':binarysecurityToken,
headers: {
Accept : "application/x-www-form-urlencoded"
},
success: function(result, textStatus, jqXHR) {
alert('done wsignin ' + result);
},
error:function (jqXHR, textStatus, errorThrown){
alert('error wsignin:' + jqXHR.responseText);
},
complete:function(jqXHR, textStatus) {
alert('complete wsignin ' + textStatus); }
});
}
So, the output of this is an error with no responseText. Can anybody
please tell me what I am doing wrong in here?
