我有一个下面 interceptor auth-interceptor.service.ts

import {Injectable, Injector} from '@angular/core';
import {HttpErrorResponse, HttpEvent, HttpHandler, HttpInterceptor, HttpRequest} from '@angular/common/http';
import {Observable} from 'rxjs/Observable';
import {Cookie} from './cookie.service';
import {Router} from '@angular/router';
import {UserService} from './user.service';
import {ToasterService} from '../toaster/toaster.service';
import 'rxjs/add/operator/catch';
import 'rxjs/add/observable/throw';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
    constructor(private injector: Injector) {}

    private handleError(err: HttpErrorResponse): Observable<any> {
        let errorMsg;
        if (err.error instanceof Error) {
            // A client-side or network error occurred. Handle it accordingly.
            errorMsg = `An error occurred: ${err.error.message}`;
        } …

我有一个auth-interceptor.service.ts处理请求

import {Injectable} from '@angular/core';
import {HttpErrorResponse, HttpEvent, HttpHandler, HttpInterceptor, HttpRequest} from '@angular/common/http';
import {Observable} from 'rxjs/Observable';
import {Cookie} from './cookie.service';
import {Router} from '@angular/router';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
    constructor(private router: Router) {}
    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // Clone the request to add the new header.
        const authReq = req.clone({headers: req.headers.set(Cookie.tokenKey, Cookie.getToken())});
        // Pass on the cloned request instead of the original request.
        return next.handle(authReq).catch(this.handleError);
    }

    private handleError(err: HttpErrorResponse): Observable<any> {
        console.log(err);
        if …
