问题 Problem: I'm unable to inject ANY service into the constructor of my HttpInterceptors. Any service that I attempt to inject into the service is met with the following error: TypeError: Cannot set property 'authenticationService' of undefined This goes for even a dummy foo service with a single function bar and no additional dependency injected into it. THE CODE interceptor.ts import { Injectable, Injector } from '@angular/core'; import { HttpRequest, HttpHandler, HttpEvent, HttpInterceptor }

问题 I have a working interceptor in Angular 5. It's registered in App.module's providers and correctly intercepts all requests made from the application. The problem is that it doesn't intercept the requests made from the libraries used by the app. I'm using an open source library (NGX-Jsonapi), and need the interceptor to provide a token in every request that the library makes to the back-end.

This function needs an access token to be able to call the API. And the access token can be gotten from getAccessToken() function in auth.service. But getAccessToen() is async. How can we get value from the async function? Note that getCustomer() must be Observable so that I can map data from response and bind to members of customer.component.

问题 I have developed the Angular 6 application. Implemented the JWT token authentication using Web API. Also implemented the HttpInterceptor to keep watch on request and send the token in every request. @Injectable() export class HttpRequestInterceptor implements HttpInterceptor { constructor(private router: Router) { } intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { var token = localStorage.getItem("bearerToken"); if (token) { const newReq = req.clone( { headers

问题 I can get the connection status using window.navigator.onLine and using the HttpInterceptor as mentioned below i can get access to requests globally. But how do i cancel a request inside the HttpInterceptor? Or else is there a better way to handle this? import { Injectable } from '@angular/core'; import { HttpRequest, HttpHandler, HttpEvent, HttpInterceptor } from '@angular/common/http'; import { Observable } from 'rxjs/Observable'; @Injectable() export class InternetInterceptor implements
