angular-http-interceptors

问题 I have already created an http interceptor and based on my observation, it only applies to all that uses $http service. What if I want to intercept even the css, html and js files used in the template? Is it possible? This is the code of the interceptor I mentioned above: app.factory('redirectInterceptor', function($q,$location,$window){ return { 'response':function(response){ if (typeof response.data === 'string' && response.data.indexOf("My Login Page")>-1) { $window.location.href = "/login

问题 I have a HTTP interceptor and before every request I check if the access token is expired, if it is, I subscribe to a http.post call from my service and then subscribe to it and when I get a new access token I call next.handle(request) like this: this.auth.refreshAccessToken().subscribe((token: string) => { this.auth.newAccessToken = token; request = request.clone({ setHeaders: { Authorization: `Bearer ${token}` } }); return next.handle(request); }); The issue is then it is throwing TypeError

问题 The following url explained how to use http interceptor in Angular 4: https://angular.io/guide/http#intercepting-all-requests-or-responses However, I'm wondering whether there is any way to choose whether to use the interceptors or not?

问题 I use a angular $http interceptor, to check if a ajax request returns 401 (not authenticated). If response is 401, the original request gets queued, a login form is shown and after login successfully, it retries the queued requests. This already works with $http, and the source for the angular interceptor is: define('common.service.security.interceptor', ['angular'], function() { 'use strict'; angular.module('common.service.security.interceptor', ['common.service.security.retryQueue'])

问题 I am using the HttpInterceptor to resend requests with a token in case they return a 401. This had worked well before, when I was just taking the cached token. Since the Firebase token does not seem to be automatically refreshed (using forceRefresh though), I am now trying to get a fresh token in realtime in the interceptor class. The problem is that now the request is not being re-send. Here is my full interceptor: export class CustomHttpInterceptor implements HttpInterceptor { constructor
