after reading the documentation on angular about http client error handling, I still don't understand why I don't catch a 401 error from the server with the code below:
export class interceptor implements HttpInterceptor {
intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
console.log('this log is printed on the console!');
return next.handle(request).do(() => (err: any) => {
console.log('this log isn't');
if (err instanceof HttpErrorResponse) {
if (err.status === 401) {
console.log('nor this one!');
}
}
});
}
}
on the console log, I also get this:
zone.js:2969 GET http://localhost:8080/test 401 ()
core.js:1449 ERROR HttpErrorResponse {headers: HttpHeaders, status: 401, statusText: "OK", url: "http://localhost:8080/test", ok: false, …}
You should catch an error using catchError
return next.handle(request)
.pipe(catchError(err => {
if (err instanceof HttpErrorResponse) {
if (err.status === 401) {
console.log('this should print your error!', err.error);
}
}
}));
