Trying to create a basic app that utilizes an http request, but facing challenges with cors in ionic 2.
To begin with, modifications were made to the ionic.config.json
{
"name": "weatherapp",
"app_id": "",
"v2": true,
"typescript": true,
"proxies": [
{
"path": "/api",
"proxyUrl": "http://api.wunderground.com/api"
},
{
"path":"/search",
"proxyUrl": "http://autocomplete.wunderground.com"
}
]
}
weather.service.ts
import {Injectable, Inject} from '@angular/core';
import {Http} from '@angular/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/Rx';
@Injectable()
export class WeatherService {
http: any;
searchUrl: any;
apiKey: string;
conditionsUrl: string;
static get parameters(){
return [Http];
}
constructor(http){
this.http = http;
console.log('Service Connected : )');
this.apiKey = '1e4420a89011eef4';
this.conditionsUrl= 'http://api.wunderground.com/api/'+this.apiKey+'/conditions/q';
this.searchUrl='http://localhost:8100/search/aq?query=';
}
getWeather(city, state){
return this.http.get(this.conditionsUrl+'/'+state+'/'+city+'.json')
.map(res => res.json());
}
searchCities(searchStr){
return this.http.get(this.searchUrl+''+searchStr)
.map(res => res.json());
}
}

While attempting to resolve the problem of "adding proxies to ionic.config.json", unfortunately, it remains unresolved.
