Question

我试图避免401错误时令牌在1小时后终止。

这是我的代码。

auth-interceptor.ts

import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HttpResponse, HttpErrorResponse } from '@angular/common/http';
import { Observable } from 'rxjs';
import 'rxjs/add/operator/do';
import { Router } from '@angular/router';
import { AuthService } from 'app/univers-auth/auth.service';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
  auth: any;
  constructor(private router: Router, private authService: AuthService) {
  }

  intercept(req: HttpRequest<any>, next: HttpHandler):
    Observable<HttpEvent<any>> {
    const auth = this.authService.auth;
    const signInUserSession = auth.getCachedSession();

    if (!signInUserSession.isValid()) {
      auth.refreshSession(signInUserSession.getRefreshToken().getToken());
    }

    const authToken = signInUserSession.getAccessToken().getJwtToken();

    const header = { Authorization: 'Bearer ' + authToken };
    const currentrole = localStorage.getItem('current-role');
    if (currentrole !== null) {
      header['currentRole'] = currentrole;
    }
    const authReq = req.clone({ setHeaders: header });
    return next.handle(authReq).do(event => { }, err => {
      if (err instanceof HttpErrorResponse && err.status === 401) {
        this.router.navigate(['logout']);
      }
    });
  }
}

但是在获得刷新会话的响应之前，api失败并带有旧令牌。

有人可以在这里帮助我吗？
