How I can post json to my serve?

In CLI “generate” command there are no “service” option.
There are another option to post json to my serve?

In Ionic you generate providers, not services. Check the documentation out.

Thanks, I Just created a provider and import it.

I have:

@Injectable()
export class ConectmeProvider {
	hi(){
		console.log('hi people');
	}
  constructor(public http: Http) {

    console.log('Hello Man ConectmeProvider Provider');
  }

}

How can I send a json with this?

It depends, to which server do you want to send it? Some database like Firebase?

Check out the Tour of Heroes http client bit.

In the file echo.php is the server side.
