It is my understanding that, as someone that has recently started using JSON web tokens that, once an access token expires, a new one may be generated using a refresh token.
I currently have some middleware on my server configured such that, if a JWT verification fails, it uses the refresh token to generate a new access token and then attempts the verification process again. If this succeeds, it sends a response with the new access token attached. If it fails, it sends a 401 error.
For this to work, however, the client must send both the access and refresh tokens. My fetch requests are currently configured such that they send the access token under the Authorization
header as Bearer [token]
.
However, when reading the JWT docs, I have come across nothing that refers to the correct manner in which to send the refresh token. A brief search returned that it should be sent in the body of a POST request, however, given I am currently sending both tokens in all fetch requests I make, this would not work for GET requests.
Should I be sending both tokens in all requests? If so how should I send the refresh token in a GET request. Given it is stored in the client cookies, I have considered extracting it from there, though I'm curious if there is a better/more generally accepted method.
