We want to implement a page that retrieves employee data from the server. If the user is not authenticated, he should be automatically redirected to the login page. The user should be able to get to the data page, only if he is logged in.
At the moment, the only way to log off the user is by closing the browser window. As we are storing the bearer token in browser session storage, when we close the browser we loose it from the session. In our next video we will discuss, how to explicitly log out the user without closing the browser window.

Hello, My understanding on Web API is that its stateless http protocol. But here we do use sessionStorage to use / identify sessions. Is it violating RESTFUL service principles ? Can you please clarify ? If my question is irrelevant please ignore.
Thank you for the video but in last you forgot to tell to remove authorized from controller. I was getting unauthorized error..
You should not remove authorized. If you are getting 401 error make sure that you have space after to Bearer (inside the string)
The word "thank you" is very little compared to what you offer to all of us.
Can anyone please tell in which table is stored the Bearer token in the server side, and is able to authenticate the client ?
Thank you very much in advance.
How the token value is differentiated from user, can 2 user from 2 different machine pass the same token in the Authorization header for calling 1 api?
I have been running this example with visual studio 2015 community edition but token request has been working fine with Fiddler and when using access_token with other request like employee Get method it has been working with Fiddler but when calling as per given example it shows error. Can someone help me out in resolving this issue.

Why does that bother everyone so much? The pay gap may be due to the positions and experience they hold.
how server validates user token for particular user for 2nd request ...where token will be saved in server..?
Token wont be saved at server side but did you able to figure it out how Token is getting validated at server side on second request ?

Hi,
How do refresh my token on every request.
For Instance.
In my API i have set expired token as 5 mins for an example, even though I'm using my web page continuously without being idle my token will be expired after 5 mins.
How do we resolve this, meaning how do i refresh token on every request or is there any way to handle this?
Hi, I made a separate location for the JS file and then added location in BundleConfig.cs. Now, If I reload data.html page and set a breakpoint at " if (sessionStorage.getItem('accessToken') == null) { window.location.href = "Login.html"; }", the step passes this condition for infinity times and as a result login page also refreshes infinity times. Could you please let me know the reason?
i got same issue how did you resolve it.
I am facing a problem which is not related to this topic. Actually, I was trying to host this Web API service on the IIS. I can access Login.html, Registration.html, Data.html pages from debugging mode. But after adding this service (publish) on the IIS I could not access those pages, it appears as a blank page. In browser console it's showing me this error message "Unchecked runtime.lastError: Could not establish the connection. Receiving end does not exist.". Does anyone know this issue or what I am doing wrong here? Thanks in advance.
how to generate "Refresh token" and "Access Token" ?
Thank you sir
Hi all, Please anyone let me know how the Token is getting validated at server side when we click on Load Employee button ?
I logged in with the credentials and when I clicked on LoadEmployees button why it says {"Message":"Authorization has been denied for this request."}
var token = sessionStorage.getItem('accessToken');
var headers = {};
if (token) {
headers.Authorization = 'Bearer ' + token;
}
$('#btnLoadHospital').click(function () {
$.ajax({
url: '/api/HospitalUser',
method: 'GET',
headers: headers,
success: function (data) {
you should consider in Authorization Header 'Bearer ',you should keep a space 'Bearer ' not 'Bearer'
