Fir example there is an ecommerce store and there are users and admins , users can login but can't see dashboard, which means they are authenticated but not authorized to do some functionalities

Hi Piyush, deployed azure api, done app registrations but req.headers.authorization underfined

@thebishalpaul 11 месяцев назад

expected more details as there were in earlier videos. For eg at 9:50 you've removed line no 7 but mentioning the reason for it would've been helpful.

@flopgameryt399 4 месяца назад

Can you provide me source code bcz my code not working after seeing this video 😢

@muhammad_haseeb_pk Месяц назад

he removed that line because previous just a 30sec before he did the same thing thing in middleware where he was checking that condition so that why he removed that from the code .

@sourabhrajwade1061 22 дня назад

Hey Piyush, nice explanation. I would like to highlight that you are doing a boolean coercion on string (for authorizationHeaderValue), I would suggest against it. Cheer !

Hi Piyush, how can we know when we have to use return in request handler, with res.send or res.redirect

@Arvind__-wu6zv 2 месяца назад

when you have a front end application like react or even using an xml request in case of simple js and you send a req on a specific route on server and expect a response. And based on that response you want to redirect or just show user the whatever you requested for is done, in that case you do req.send from server. for example, you created a todo list and you make a request on a endpoint that saves your todo and in response send an object which contains details of todo and a message which you can now render in react or if you are using js, you display some message. On the other hand, lets say you want to login and you fill the details on frontend and make a request on an endpoint which checks for credentials, now if the details are correct, there's no point of sending an object in response, you can simply redirect to homepage from server using res.redirect('/home'). You should know that you can redirect either from backend or even from front end. For example, in login case if credentials are correct you can send an object in response that contains a message that logged in successfully, render it on alert on login page and then redirect to home page from frontend. Its up to you what you want to send from server.

how to check the user is logged in or not in reactjs?

@ilikethemost 5 месяцев назад

check access token of user ,if access token is expired then check refresh token in db is that is expired or not available then user in logged out else if access token is available then he is logged in ...that's basic concept
