我在Angular HTTP拦截器代码中使用错误捕获时遇到了一个奇怪的问题。
似乎我的“.then（）”语句链中的代码以某种方式被无序地触发。
这是我的代码...

import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HTTP_INTERCEPTORS, HttpClient, HttpErrorResponse } from '@angular/common/http';
import { catchError, Observable, retry, switchMap, throwError } from 'rxjs';
import { FirebaseService } from '../services/firebase.service';
import { getAuth } from 'firebase/auth';

@Injectable()
export class HttpRequestInterceptor implements HttpInterceptor {

  //AW-Note: Adding this in here to try the appearance of "Persistent Login"
  static accessToken = '';
  static apiKey = 'API_KEY_HERE';

  constructor(private firebaseService: FirebaseService, private http: HttpClient) { }
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = localStorage.getItem('token');

    function refreshToken(): Promise<string> {
      // api call returns Promise<string>
      const auth = getAuth();
      const myUser = auth.currentUser;
      return myUser!.getIdToken(true);
    }

    async function getNewToken(): Promise<string> {
      const value = await refreshToken() // how to unwrap the value inside this  promise
      return value;
    }


    console.log('Flowing through HTTP Interceptor');

    req = req.clone({
      //If you comment out the below line you will no longer send Credentials with the request  
      withCredentials: true,
      setHeaders: { Authorization: `Bearer ${token}` }
    });

    return next.handle(req).pipe(/*retry(10),*/ catchError((err: HttpErrorResponse) => {
      console.log("ERROR FOUND! CHECKING TO SEE IF IT IS A 401 ERROR NEXT. Error: " + err);
      if (err.status === 401 || err.status === 0) {
        console.log("NEW TOKEN NEEDED - Yo we got that 401 error going on - let's try and refresh that thang");

        //Refresh Token from Firebase

        console.log("Old Token: " + JSON.stringify(token));


        console.log("Attempting to refresh token now...");

        getNewToken()
          .then((newToken) => {
            console.log('New Token: ' + JSON.stringify(newToken));
            localStorage.setItem('token', newToken);
            console.log('Updated Local Storage with new token');
          })
          .then(() => {
            console.log("Here is where the request will refresh");
            return next.handle(req.clone({
              withCredentials: true,
              setHeaders: {
                Authorization: `Bearer ${localStorage.getItem('token')}`
              }
            }))
          })
          .catch((error) => {
            console.log("Error in Getting new token... Error: " + JSON.stringify(error));
          });
      }
      return throwError(() => err);
    }))
  }
}

export const httpInterceptorProviders = [
  { provide: HTTP_INTERCEPTORS, useClass: HttpRequestInterceptor, multi: true },
];

因此，一旦localStorage中的令牌过期，代码就成功地检测到错误，并且在第一个“pipe（）”块中捕获了它。
它成功地从Firebase获得了一个新令牌，但是当它向下移动到最后的“then”语句以使用新令牌重试API调用时，似乎在控制台日志语句“正在尝试刷新令牌...”之后立即调用了API，而不是像我期望的那样“这里是请求将刷新的地方”。
这是控制台的输出，所以你可以看到我在说什么...

这里的任何帮助都将不胜感激。我的.then（）语句有问题吗？对 typescript 、角化和像这样的promise处理来说相当陌生。谢谢。
我已经尝试过在.then（）语句周围使用一些语句，但是我认为return语句看起来似乎执行得 * 早 *
(the HTTP请求在日志显示“HttpErrorResponse”的位置发出）
提前感谢！
