TypeError: token.split не является функцией

Question

При входе в систему произошла ошибка, которая не ожидается, но я пытаюсь решить ее за 2 дня, но не могу.Я использую Nodejs для API и Angular 7 для веб-интерфейса

Я отправил часть кода с ошибкой, пожалуйста, помогите мне решить эту проблему СПАСИБО В НАЛИЧИИ

auth.service.ts

import { Injectable } from "@angular/core";
import { Observable } from "rxjs";
import "rxjs/Rx";
import { JwtHelperService } from "@auth0/angular-jwt";
import "core-js/es7/reflect";

import { HttpClient } from "@angular/common/http";

const jwt = new JwtHelperService();
@Injectable()
export class AuthService {
  private decodedToken;
  constructor(private http: HttpClient) {}
  public register(userData: any): Observable<any> {
    return this.http.post("/api/v1/users/register", userData);
  }
  public login(userData: any): Observable<any> {
    return this.http.post("/api/v1/users/auth", userData).map(token => {
      //debugger;
      return this.saveToken(token);
    });
  }

  private saveToken(token): string {
    //debugger;
    this.decodedToken = jwt.decodeToken(token);
    localStorage.setItem("bwm_auth", token.token);
    localStorage.setItem("bwm_meta", JSON.stringify(this.decodedToken));
    return token;
  }
}

Answer 1

Как представляется, токен, возвращаемый с сервера, не является строковым типом

public login(userData: any): Observable<any> {
    return this.http.post("/api/v1/users/auth", userData).map(token => {
      //debugger;
      return this.saveToken(token);
    });
  }

попробуйте проверить, что возвращается с сервера
