Repeat request in error interceptor sends old header

[faradoxuz]

Hello, I am using restangular library in my application
in error addErrorInterceptor config I want to repeat request if user access token expires after refreshing the token. here is piece of my code:

.addErrorInterceptor((response, subject, responseHandler) => {
            if (response.status === 401) {
                authService.refreshAccesstoken()
                    .pipe(
                        switchMap(refreshAccesstokenResponse => {
                            console.log(refreshAccesstokenResponse) // this is new token
                            response.request.headers.set('Authorization', `Bearer  ${refreshAccesstokenResponse}`)
                            return response.repeatRequest(response.request.clone());
                        })
                    )
                    .subscribe(
                        res => {
                            console.log(res);
                            responseHandler(res)
                        },
                        err => subject.error(err)
                    );
                return false; // error handled
            }

after setting headers, they are not updating, it still send old headers

Hi,

You must update the headers cloning the headers and then just repeat the request

        const newHeaders = new HttpHeaders({ 'Authorization': BEARER_KEYWORD + authService.getAccessToken() });
        const newRequest = response.request.clone({ headers: newHeaders });
            return response.repeatRequest(newRequest);

It works for me, hope for you too

Hi @faradoxuz, @leoxgnr93 code sample should work. Updated readme file in #177
