Friends, I would like to have the save method in the class itself, and I’m not getting it, I’m beginner in typescript.
import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
@Injectable()
export class Usuario {
http: Http;
nome: string;
apelido: string;
email: string;
tel: string;
senha: string;
salvar(usuario){
this.http.post("http://localhost:5000/users",JSON.stringify(usuario), {})
.toPromise()
.then(res => console.log(res.json().data))
.catch();
}
}
get the bug:
browser_adapter.js:84 ORIGINAL EXCEPTION: TypeError: Cannot read property 'post' of undefined
Have you looked before
chmod
(type permission)? it is saying error Undefined is empty.– KingRider
already yes, permissions are normal.

It seems that he is not accepting his "this.http". All the examples I saw and in a code I made http arrow in the constructor, I haven’t had time to test yet, but I use constructor(private http:Http) {}. Even empty as you can see on this link http://www.gajotres.net/ionic-2-making-rest-http-requests-like-a-pro/

exactly @Andrévicente, but when I try to instantiate a User object, "Let usuario = new User()" is the error, because I asked to pass http as a parameter in the constructor. My idea is to set the attributes in the User object and save the same in the database.
