I'm building a website using angular 4 and nodejs. When I try to log in, node sends the data, to angular, which works fine. Its just that when I attempt the login, data doesn't gets stored in local storage.
Here is the code of auth.services.ts
import { Injectable } from '@angular/core';
import { Http, Headers } from '@angular/http';
import 'rxjs/add/operator/map';
import { tokenNotExpired } from 'angular2-jwt';
import { Router } from '@angular/router';
//import { User } from '../../User';
@Injectable()
export class AuthService {
authToken: any;
user: any;
constructor(private http:Http, private router: Router) {
console.log("authorization service initialized...");
}
signIn(user) {
let headers = new Headers();
headers.append('Content-Type', 'application/json');
return this.http.post('http://localhost:3000/users/login', JSON.stringify(user), {headers: headers})
.map(res => res.json());
}
storeUserData(token, user) {
console.log("storeuserdata");
localStorage.setItem('id_token', token);
localStorage.setItem('user', JSON.stringify(user));
this.authToken = token;
this.user = user;
}
logout() {
this.authToken = null;
this.user = null;
localStorage.clear();
this.router.navigateByUrl('/');
}
getProfile() {
let headers = new Headers();
this.loadToken();
headers.append('Authorization', this.authToken);
headers.append('Content-type', 'application/json');
return this.http.get('http://localhost:3000/users/profile', {headers: headers})
.map(res => res.json());
}
loadToken() {
this.authToken = localStorage.getItem('id_token');
}
loggedIn() {
return tokenNotExpired();
}
}
Here is the navbar.component.ts since it contains the login part
import { Component, OnInit } from '@angular/core';
import { FormGroup, FormControl, Validators} from '@angular/forms';
import { Router } from '@angular/router';
import { AuthService } from '../../services/auth.service';
//import { User } from '../../../User';
@Component({
moduleId: module.id,
selector: 'navbar',
templateUrl: `./navbar.component.html`,
})
export class NavBarComponent implements OnInit{
signInForm: FormGroup;
constructor(private authService: AuthService, private router: Router) {}
OnSignIn() {
const user = {
email: this.signInForm.value.email,
password: this.signInForm.value.password
};
this.authService.signIn(user)
.subscribe(
data => {
console.log(data);
if (data.success) {
this.authService.storeUserData(data.token, data.user);
this.router.navigateByUrl('profile');
} else {
}
},
error => console.log(error)
);
this.signInForm.reset();
}
ngOnInit() {
this.signInForm = new FormGroup({
email: new FormControl(null, [
Validators.required,
Validators.pattern("[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?")
]),
password: new FormControl(null, Validators.required)
});
}
onLogout() {
this.authService.logout();
}
}
This is what I receive when I attempt login
Object {success: true, token: "JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyIkX18iO…Tc0fQ.rte25znZW9oASt-6scViAbA37W1DzXxCcg0Z_CMKWTY", user: Object}
and I also get success from the node js part.
When I build this website I was using angular 2. I got busy with my classes and didn't have time to finish it and angular 4 was released. I copied all the code to a fresh directory and made sure that all the node modules are build from start.
Here is my package.json that i had before:
{

"version": "0.0.0",
"license": "MIT",
"scripts": {
"ng": "ng",
"start": "ng serve",

}
and this is the new package.json
{

"typescript": "~2.2.0"
}
}
When I run the app with old version of node_modules, it works finne but when I use the new version, user never logs in.
Can someone please help me with this? Thanks
