TypeError: error.json is not a function

Question

Edit: Read the part at the end of the question!

I get this error:

My service code:

import { Http, Response, Headers } from \         


        

Answer 1

Just Make Changes into your app.module.ts file

import { HttpModule} from "@angular/http";

@NgModule({

declarations: [

---- ],
imports: [ BrowserModule, HttpModule],

providers: [
    DataService
],   
bootstrap: [
   AppComponent
]})

This will fix your issue now in updated version of angular the methods are rewritten.
