Having difficulty generating a new object and implementing the export class feature in Angular 2

Here is the UserDetails class defined:

export class UserDetails {
name:string;
phoneNumber:string;
email:string;
password: string;
 }

Below is a service where userDetails are utilized::

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { userDetails } from './_models/index';
import 'rxjs/add/operator/map'

@Injectable()
export class AuthenticationService {
private loginUserUrl="http://localhost:8082/TodoApp/login";

constructor(private http: HttpClient) {
//let user = new UserDetails();
}

login(email: string, password: string) {
    console.log("in login service");

    let user = new User();
   user.email=email;
    user.password=password;

    return this.http.post(this.loginUserUrl,user)
    .map(user => {
            // login successful if there's a jwt token in the 
             response
            if (user && user.token) {
                // store user details and jwt token in local storage to keep user logged in between page refreshes
                localStorage.setItem('currentUser', JSON.stringify(user));
            }

            return user;
        });
      }

}

Error: ReferenceError: UserDetails is not defined at AuthenticationService.login (webpack-internal:///../../../../../src/app/_services/authentication.service.ts:25)

Answer №1

Here's a suggestion:

import { UserInformation as UserInfo } from './models/index';
//...
let userInfo = new UserInfo();

Answer №2

It seems that there is an error in your import statement. You have used userDetails instead of UserDetails. To fix this, please update the import statement to:

import { UserDetails } from './_models/index';

After updating the import statement, make sure to create the object as follows:

 let user = new UserDetails();

Answer №3

To properly set up a model variable in your constructor for UserDetails, you should do the following:

constructor(private http: HttpClient, private user:UserDetails) {

}

By implementing this code, it will instantiate an object user of type UserDetails, allowing you to manipulate it similar to how you interact with http. For example,

this.user.email=email;
this.user.password=password;
