i have code in ionic v1
appServices.factory('apiPesawatService', function($http) {
var baseUrl = 'http://api.com/getdata.php?';
return {
getAll: function(data){
//console.log(JSON.stringify(baseUrl+ $.param(data)));
return $http.get(baseUrl+ $.param(data));
//return $http.jsonp(baseUrl, {jsonpCallbackParam: 'callback'});
},
};
});
and the problem is how to make $ .param (data) in ionic v1 work in ionic v2 
The frameworks are so different that thinking of how to make AngularJS construct X work in modern Angular is not very useful. The modern Angular HttpClient is documented here, I would just read that and rewrite your service from scratch.
of course i know it but after i try and not insert the $ .params i get is [Object Object]
provider service.ts
import { Http, Response ,Headers, RequestOptions } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';
let baseUrl='http://api.blabla.com/getdata.php?';
@Injectable()
export class ApiPesawatService {
constructor(public http: Http) {
console.log('Hello ApiPesawatServiceProvider Provider');
}
getAll(data:any) {
return new Promise((resolve, reject) => {
console.log(JSON.stringify(baseUrl+ data));
return this.http.get(baseUrl+ data)
.subscribe(res => {
resolve(res.json());
}, (err) => {
reject(err);
});
});
//return $http.jsonp(baseUrl, {jsonpCallbackParam: 'callback'});
}
}
etiket.ts
searchEtiket(etiket, $event){
let loadingPopup = this.loadingCtrl.create({

loadingPopup.present();
this.storage.get('blabla_m').then((prof) => {
this.datauser = JSON.parse(prof);

I think this code is a complete disaster, so somebody else is going to have to try to help you.
i think so
