All I want to know is to show the upcoming events from my calendar.
Have anyone any idea how to solve this?

You might try to make sure it is a public calendar.
You can also embed googles calendar in a webpage directly- in calendars/settings
You could also try something like this:

sending notification in pusher private channel to selected users laravel8

I'm sending notifications using the public pusher channel in laravel8 .. How can I turn it to a private channel in order to send notifications just to the selected user.. which the admin selected from the dropdown menu?
here is my controller
public function notification(MessageRequest $request){
$data =[

event(new NewNotification($data));
return redirect()->back()->with(['success'=>'success']);
}
My event :
class NewNotification implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;

$this->title = $data['title'];
$this->body = $data['body'];
// $this->users = $data['users'];
}
/**

public function broadcastOn()
{
return new Channel('notification');

Adal.js not setting props in localStorage

I'm having a problem using the adal.js library without Angular. (I'm using Vue.js.)
I have an authentication context instance, which is constructed with the following options (exact values have been changed to protect the innocent):
let config = {
tenant: '<tenant id>',
clientId: '<client id>',
redirectUri: 'http://myapplication.com/index.html',
// popUp: true,
cacheLocation: 'localStorage'
}
On my login page, I call authContext.login(), which redirects me first to https://login.microsoftonline.com/, where I log into AAD. Upon successful login, another redirect takes me back to my application, at the URI I've configured above, along with an id_token parameter in the URL. However, no token or other properties are stored by the library in local storage, just a few properties that are the result of the configuration.
On successful login, All I've got in localStorage is
{
adal.access.token.key: "",
adal.error: ""
adal.error.description: ""
adal.expiration.key: "0"
adal.idtoken: ""
adal.login.error: ""
adal.login.request: "http://myapplication.com/#/login"
adal.nonce.idtoken: "<a non-empty string>"
adal.session.state: ""
adal.state.login: "<a non-empty string>"
adal.token.keys: ""
adal.username: ""
}
So, as far as AAD is concerned, I've successfully authenticated, but the library itself seems to have no notion of what user is logged in, what tokens are associated with them, when the token expires, etc. Any advice on how to proceed would be most appreciated. Thank you in advance for reading.
Active Directory Authentication Library for JavaScript (ADAL JS) helps you to use Azure AD for handling authentication in your single page applications. This library is optimized for working together with AngularJS.
It will not save the tokens into the cache unless we code it. You can check the relative code from adal-angular.js. Here is a piece of code for your reference:
The saveTokenFromHash method will also save the tokens into cache and this function will execute after the page redirect back to the Angular app.
adal.js:
AuthenticationContext.prototype.saveTokenFromHash = function (requestInfo) {
this._logstatus('State status:' + requestInfo.stateMatch);
this._saveItem(this.CONSTANTS.STORAGE.ERROR, '');
this._saveItem(this.CONSTANTS.STORAGE.ERROR_DESCRIPTION, '');
// Record error
if (requestInfo.parameters.hasOwnProperty(this.CONSTANTS.ERROR_DESCRIPTION)) {
this._logstatus('Error :' + requestInfo.parameters.error);
this._logstatus('Error description:' + requestInfo.parameters[this.CONSTANTS.ERROR_DESCRIPTION]);
this._saveItem(this.CONSTANTS.STORAGE.FAILED_RENEW, requestInfo.parameters[this.CONSTANTS.ERROR_DESCRIPTION]);
this._saveItem(this.CONSTANTS.STORAGE.ERROR, requestInfo.parameters.error);
this._saveItem(this.CONSTANTS.STORAGE.ERROR_DESCRIPTION, requestInfo.parameters[this.CONSTANTS.ERROR_DESCRIPTION]);
if (requestInfo.requestType === this.REQUEST_TYPE.LOGIN) {
this._loginInProgress = false;
this._saveItem(this.CONSTANTS.STORAGE.LOGIN_ERROR, requestInfo.parameters.errorDescription);
} else {
this._renewActive = false;
}
} else {
// It must verify the state from redirect
if (requestInfo.stateMatch) {
// record tokens to storage if exists
this._logstatus('State is right');
if (requestInfo.parameters.hasOwnProperty(this.CONSTANTS.SESSION_STATE)) {
this._saveItem(this.CONSTANTS.STORAGE.SESSION_STATE, requestInfo.parameters[this.CONSTANTS.SESSION_STATE]);
}
var keys, resource;
if (requestInfo.parameters.hasOwnProperty(this.CONSTANTS.ACCESS_TOKEN)) {
this._logstatus('Fragment has access token');
// default resource
this._renewActive = false;
resource = this.config.loginResource;
if (!this._hasResource(resource)) {
keys = this._getItem(this.CONSTANTS.STORAGE.TOKEN_KEYS) || '';
this._saveItem(this.CONSTANTS.STORAGE.TOKEN_KEYS, keys + resource + this.CONSTANTS.RESOURCE_DELIMETER);
}
if (requestInfo.requestType === this.REQUEST_TYPE.RENEW_TOKEN) {
resource = this._getResourceFromState(requestInfo.stateResponse);
}
// save token with related resource
this._saveItem(this.CONSTANTS.STORAGE.ACCESS_TOKEN_KEY + resource, requestInfo.parameters[this.CONSTANTS.ACCESS_TOKEN]);
this._saveItem(this.CONSTANTS.STORAGE.EXPIRATION_KEY + resource, this._expiresIn(requestInfo.parameters[this.CONSTANTS.EXPIRES_IN]));
}
if (requestInfo.parameters.hasOwnProperty(this.CONSTANTS.ID_TOKEN)) {
this._loginInProgress = false;
this._user = this._createUser(requestInfo.parameters[this.CONSTANTS.ID_TOKEN]);
if (this._user && this._user.profile) {
if (this._user.profile.nonce !== this._getItem(this.CONSTANTS.STORAGE.NONCE_IDTOKEN)) {
this._user = null;
this._saveItem(this.CONSTANTS.STORAGE.LOGIN_ERROR, 'Nonce is not same as ' + this._idTokenNonce);
} else {
this._saveItem(this.CONSTANTS.STORAGE.IDTOKEN, requestInfo.parameters[this.CONSTANTS.ID_TOKEN]);
// Save idtoken as access token for app itself
resource = this.config.clientId;
if (!this._hasResource(resource)) {
keys = this._getItem(this.CONSTANTS.STORAGE.TOKEN_KEYS) || '';
this._saveItem(this.CONSTANTS.STORAGE.TOKEN_KEYS, keys + resource + this.CONSTANTS.RESOURCE_DELIMETER);
}
this._saveItem(this.CONSTANTS.STORAGE.ACCESS_TOKEN_KEY + resource, requestInfo.parameters[this.CONSTANTS.ID_TOKEN]);
this._saveItem(this.CONSTANTS.STORAGE.EXPIRATION_KEY + resource, this._user.profile.exp);
}
}
}
} else {
this._saveItem(this.CONSTANTS.STORAGE.ERROR, 'Invalid_state');
this._saveItem(this.CONSTANTS.STORAGE.ERROR_DESCRIPTION, 'Invalid_state');
if (requestInfo.requestType === this.REQUEST_TYPE.LOGIN) {
this._saveItem(this.CONSTANTS.STORAGE.LOGIN_ERROR, 'State is not same as ' + requestInfo.stateResponse);
}
}
}
};
And this function will be called in this.$get like below:
// special function that exposes methods in Angular controller
// $rootScope, $window, $q, $location, $timeout are injected by Angular
this.$get = ['$rootScope', '$window', '$q', '$location', '$timeout', function ($rootScope, $window, $q, $location, $timeout) {
var locationChangeHandler = function () {
var hash = $window.location.hash;
if (_adal.isCallback(hash)) {
// callback can come from login or iframe request
var requestInfo = _adal.getRequestInfo(hash);
_adal.saveTokenFromHash(requestInfo);
$window.location.hash = '';
if (requestInfo.requestType !== _adal.REQUEST_TYPE.LOGIN) {
_adal.callback = $window.parent.AuthenticationContext().callback;
}
// Return to callback if it is send from iframe
if (requestInfo.stateMatch) {
if (typeof _adal.callback === 'function') {
// Call within the same context without full page redirect keeps the callback
if (requestInfo.requestType === _adal.REQUEST_TYPE.RENEW_TOKEN) {
// Idtoken or Accestoken can be renewed
if (requestInfo.parameters['access_token']) {
_adal.callback(_adal._getItem(_adal.CONSTANTS.STORAGE.ERROR_DESCRIPTION), requestInfo.parameters['access_token']);
return;
} else if (requestInfo.parameters['id_token']) {
_adal.callback(_adal._getItem(_adal.CONSTANTS.STORAGE.ERROR_DESCRIPTION), requestInfo.parameters['id_token']);
return;
}
}
} else {
// normal full login redirect happened on the page
updateDataFromCache(_adal.config.loginResource);
if (_oauthData.userName) {
//IDtoken is added as token for the app
$timeout(function () {
updateDataFromCache(_adal.config.loginResource);
$rootScope.userInfo = _oauthData;
// redirect to login requested page
var loginStartPage = _adal._getItem(_adal.CONSTANTS.STORAGE.START_PAGE);
if (loginStartPage) {
$location.path(loginStartPage);
}
}, 1);
$rootScope.$broadcast('adal:loginSuccess');
} else {
$rootScope.$broadcast('adal:loginFailure', _adal._getItem(_adal.CONSTANTS.STORAGE.ERROR_DESCRIPTION));
}
}
}
} else {
// No callback. App resumes after closing or moving to new page.
// Check token and username
updateDataFromCache(_adal.config.loginResource);
if (!_adal._renewActive && !_oauthData.isAuthenticated && _oauthData.userName) {
if (!_adal._getItem(_adal.CONSTANTS.STORAGE.FAILED_RENEW)) {
// Idtoken is expired or not present
_adal.acquireToken(_adal.config.loginResource, function (error, tokenOut) {
if (error) {
$rootScope.$broadcast('adal:loginFailure', 'auto renew failure');
} else {

}
}
});
}
}
}
$timeout(function () {
updateDataFromCache(_adal.config.loginResource);
$rootScope.userInfo = _oauthData;
}, 1);
}
...
And here is a sample code which could save the tokens into cache for your reference:

<script src="node_modules\adal-angular\lib\adal.js"> </script>
<script src="config.js"> </script>

var pathDefault = window.location.href;
if (existingHash) {

}
configOptions.redirectUri = configOptions.redirectUri || pathDefault;
configOptions.postLogoutRedirectUri = configOptions.postLogoutRedirectUri || pathDefault;
// create instance with given config
} else {
throw new Error('You must set configOptions, when calling init');
}
// loginresource is used to set authenticated status
updateDataFromCache(authContext.config.loginResource);
}
var _oauthData = { isAuthenticated: false, userName: '', loginError: '', profile: '' };
var updateDataFromCache = function (resource) {
// only cache lookup here to not interrupt with events
var token = authContext.getCachedToken(resource);
_oauthData.isAuthenticated = token !== null && token.length > 0;
var user = authContext.getCachedUser() || { userName: '' };

Linkedin API: Exchange JSAPI Token for REST API OAuth Token

I'm having some difficulty exchanging my JSAPI token for a REST API token. I'm using this for reference:
https://developer-programs.linkedin.com/documents/exchange-jsapi-tokens-rest-api-oauth-tokens
I've: set up a self signed SSL cert locally, so Linkedin's secure cookie works properly; given my app r_basicprofile and r_emailaddress permissions.
Here's my front end code:
<script type="text/javascript" src="//platform.linkedin.com/in.js">
api_key: **MY_CLIENT_ID**
authorize: true
credentials_cookie: true
</script>
...
$('.linkedin-signin').click(function(e) {
IN.User.authorize( function () {
IN.API.Raw("/people/~").result(function(data) {
$.post(location.origin+'/api/account/create/linkedin', { 'lId': data.id } ).done(function(result) {
console.log(result);
});
});
});
return false;
});
And here is my PHP code, which is almost exactly as in their docs:
$consumer_key = '**MY_CLIENT_ID**';
$consumer_secret = '**MY_CLIENT_SECRET**';
$cookie_name = "linkedin_oauth_${consumer_key}";
$credentials_json = $_COOKIE[$cookie_name];
$credentials = json_decode($credentials_json);
$access_token_url = 'https://api.linkedin.com/uas/oauth/accessToken';
$oauth = new OAuth($consumer_key, $consumer_secret);
$access_token = $credentials->access_token;
// swap 2.0 token for 1.0a token and secret
$oauth->fetch($access_token_url, array('xoauth_oauth2_access_token' => $access_token), OAUTH_HTTP_METHOD_POST);
Everything looks good, but on $oauth->fetch, I get the error:
OAuthException(code: 401): Invalid auth/bad request (got a 401, expected HTTP/1.1 20X or a redirect)
Which leads me to believe that the token is invalid... but it's taken directly from the cookie, so how could it be invalid? Any ideas?
Today we got the weird 401 error too, apperently linkedin was broken, because after an hour it worked again without any changes on our side.
I found this site though and eventhough it's a really old post, i tought i'd share how we fixed it, which works.
JS Front-end
var AppConfig = {
linkedin : {
onLoad : "linkedinLibInit",
api_key : 'YOUR_API_KEY',
authorize : false,
credentials_cookie: true
}
};
window.linkedinLibInit = function ( response ) {
// post init magic
// cleanup window callback function
delete window.linkedinLibInit;
}
$.getScript( "//platform.linkedin.com/in.js?async=true", function success() {
IN.init( AppConfig.linkedin );
} );
function connectToLinkedIn() {
if ( IN.User.isAuthorized() ) {
_linkedinAuthorized();
}
else {
IN.User.authorize( _linkedinAuthorized );
}
}
function _linkedinAuthorized() {
IN.API.Profile( "me" )
.fields( 'id', 'first-name', 'last-name', 'location', 'industry', 'headline', 'picture-urls::(original)', 'email-address' )
.result( function ( response ) {
var accessToken = JSON.parse( $.cookie( 'linkedin_oauth_' + AppConfig.linkedin.api_key ) );
// performApi Call to backend
} )
.error( function ( err ) {
// render error
} );
}
PHP Backend using PECL oAuth
function offlineAuthLinkedIn($accessToken, $linkedinConfig) {
$oAuth = new \OAuth( $linkedinConfig['app_id'], $linkedinConfig['app_secret'] );
$oAuth->fetch(
'https://api.linkedin.com/uas/oauth/accessToken',
array('xoauth_oauth2_access_token' => $accessToken),
OAUTH_HTTP_METHOD_POST
);
$response = null;
parse_str($oAuth->getLastResponse(), $response);
$oAuth->setToken($response['oauth_token'], $response['oauth_token_secret']);
$oAuth->fetch(
'http://api.linkedin.com/v1/people/~:(id,first-name,last-name,formatted-name,headline,location,picture-url,picture-urls::(original),public-profile-url)',
array(),
OAUTH_HTTP_METHOD_GET,
array('x-li-format' => 'json')
);
$profile = json_decode($oAuth->getLastResponse(), true);
$profile['user_id'] = $profile['id'];
if (true == isset($profile['pictureUrl']))
{
$profile['profile_image'] = $profile['pictureUrl'];
unset($profile['pictureUrl']);
}
return $profile;

You have to set the enablejsapi parameter to 1 in your iframe embed link.
By default, the parameter is set to 0 and unless you set it to 1, the callbacks won't work.

Creating a pdf from a Knockout JS view & viewModel

Scenario: In our application a user can create a invoice by filling in certain fields on a Knockout view. This invoice can be previewed, via another Knockout page. I want to use the preview url within our PDF creator (EVOPdf), so we can provide the user with a PDF from this invoice.
To preview the invoice we load the data (on document ready) via an ajax-request:
var InvoiceView = function(){
function _start() {
$.get("invoice/GetInitialData", function (response) {
var viewModel = new ViewModel(response.Data);
ko.applyBindings(viewModel, $("#contentData").get(0));
});
};
return{
Start: _start
};
}();
My problem is within the data-binding when the PDF creator is requesting the url: the viewModel is empty. This makes sense because the GetInitialData action is not called when the PDF creator is doing the request. Calling this _start function from the preview page directly at the end of the page does not help either.
<script type="text/javascript">
$(document).ready(function() {
InvoiceView.Start();
});
</script>
Looking at the documentation of EvoPdf, JavaScript should be executed, as the JavaScriptEnabled is true by default: http://www.evopdf.com/api/index.aspx
How could I solve this, or what is the best approach to create an pdf from a knockout view?
Controller action code:
public FileResult PdfDownload(string url)
{
var pdfConverter = new PdfConverter();
// add the Forms Authentication cookie to request
if (Request.Cookies[FormsAuthentication.FormsCookieName] != null)
{
pdfConverter.HttpRequestCookies.Add(
FormsAuthentication.FormsCookieName,
Request.Cookies[FormsAuthentication.FormsCookieName].Value);
}
var pdfBytes = pdfConverter.GetPdfBytesFromUrl(url);
return new FileContentResult(pdfBytes, "application/pdf");
}
Javascript:
var model = this;
model.invoiceToEdit = ko.observable(null);
model.downloadInvoice = function (invoice) {
model.invoiceToEdit(invoice);
var url = '/invoice/preview';
window.location.href = '/invoice/pdfDownload?url=' + url;
};
The comment of xdumaine prompted me to think into another direction, thank you for that!
It did take some time for the Ajax request to load, but I also discovered some JavaScript (e.g. knockout binding) errors along the way after I put a ConversionDelay on the pdf creator object
pdfConverter.ConversionDelay = 5; //time in seconds
So here is my solution for this moment, which works for me now:
To start the process a bound click event:
model.downloadInvoice = function (invoice) {
var url = '/invoice/preview/' + invoice.Id() + '?isDownload=true';
window.open('/invoice/pdfDownload?url=' + url);
};
which result in a GET resquest on the controller action
public FileResult PdfDownload(string url)
{
var pdfConverter = new PdfConverter { JavaScriptEnabled = true };
// add the Forms Authentication cookie to request
if (Request.Cookies[FormsAuthentication.FormsCookieName] != null)
{
pdfConverter.HttpRequestCookies.Add(
FormsAuthentication.FormsCookieName,
Request.Cookies[FormsAuthentication.FormsCookieName].Value);
}
pdfConverter.ConversionDelay = 5;
var absolutUrl = ToAbsulte(url);
var pdfBytes = pdfConverter.GetPdfBytesFromUrl(absolutUrl);
return new FileContentResult(pdfBytes, "application/pdf");
}
The Pdf creator is requesting this action on the controller, with isDownload = true (see bound click event):
public ActionResult Preview(string id, bool isDownload = false)
{
return PartialView("PdfInvoice", new InvoiceViewModel
{
IsDownload = isDownload,
InvoiceId = id
});
}
Which returns this partial view:
PartialView:
// the actual div with bindings etc.
#if (Model.IsDownload)
{
//Include your javascript and css here if needed
#Html.Hidden("invoiceId", Model.InvoiceId);
<script>
$(document).ready(function () {
var invoiceId = $("#invoiceId").val();
DownloadInvoiceView.Start(invoiceId);
});
</script>
}
JavaScript for getting the invoice and apply the knockout bindings:
DownloadInvoiceView = function() {
function _start(invoiceId) {
$.get("invoice/GetInvoice/" + invoiceId, function(response) {
var viewModel = new DownloadInvoiceView.ViewModel(response.Data);
ko.applyBindings(viewModel, $("#invoiceDiv").get(0));
});
};
return {
Start: _start
};
}();
DownloadInvoiceView.ViewModel = function (data) {
var model = this;
var invoice = new Invoice(data); //Invoice is a Knockout model
return model;
};
