jwtInterceptor - tokenGetter is not called because of angular caching

[RayzRazko]

Hi guys. I noticed that sometimes tokenGetter is not called during request and instead of sending refresh token request to fetch updated access token, interceptor just do nothing. As I understand angular caches headers and because of next lines the tokenGetter is not called:

request.headers = request.headers || {};
// Already has an Authorization header
if (request.headers[config.authHeader]) {
    return request;
}

Maybe it will be better to add configurable parameter, something like "forceHearedUpdate" and if this parameter is true then omit the if (request.headers[config.authHeader]) branch of code.

Hi. I've noticed this too, but it happens in a very random fashion. Do you know any concrete methods to reproduce this? When does Angular cache the headers?

[RayzRazko]

It's hard to define steps, but it happens really often.

You could be right, by removing the header check the issue seemed to vanish. But it's strange nonetheless.

I take back everything. My issue was different: in the tokenGetter method I checked if the token has expired and only then did I call the refresh API method. When the client clock and the server clock weren't in sync it could happen, that the client sees an expired token as valid and would not call the refresh method.

Hi, maybe I am a bit late to the party. Is the issue solved now? Does adding a random string to the end of the URL help?
