Hi I'm new to sharepoint. So I'm trying to develeop sharepoint online app. But there is an error here and I can't find how solve this issue. Error is :
Access denied. You do not have permission to perform this action or access this resource.
App deployed to sharepoint online site. I wrote a script into App.js
function initializePage()
{
var hostUrl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
var currentcontext = new SP.ClientContext.get_current();
var context = new SP.AppContextSite(currentcontext, hostUrl);
var web = context.get_web();
var slider_list = web.get_lists().getByTitle("Slider");
//var context = SP.ClientContext.get_current();
//var user = context.get_web().get_currentUser();
var user = web.get_currentUser();
// This code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
$(document).ready(function () {
getUserName();
});
// This function prepares, loads, and then executes a SharePoint query to get the current users information
function getUserName() {
currentcontext.load(user);
currentcontext.executeQueryAsync(onGetUserNameSuccess, onGetUserNameFail);
currentcontext.load(slider_list);
currentcontext.executeQueryAsync(onSuccess, onFail);
}
// This function is executed if the above call is successful
// It replaces the contents of the 'message' element with the user name
function onGetUserNameSuccess() {
$('#message').text('Hello ' + user.get_title());
}
// This function is executed if the above call fails
function onGetUserNameFail(sender, args) {
alert('Failed to get user name. Error:' + args.get_message());
}
function onSuccess() {
console.log(slider_list);
}
// This function is executed if the above call fails
function onFail(sender, args) {
console.log(args.get_message());
}
}
function getQueryStringParameter(urlParameterKey) {
var params = document.URL.split('?')[1].split('&');
var strParams = '';
for (var i = 0; i < params.length; i = i + 1) {
var singleParam = params[i].split('=');
if (singleParam[0] == urlParameterKey)
return decodeURIComponent(singleParam[1]);
}
}
But I get this error everytime which is wrote above. I hope anyone help me.
