I\'m having trouble converting RSS to JSON using the rrs2json API with Ionic 3. If I execute the code it gives me the error --> Response {_body: \"{\" status \":\" error \",\" m

Alright. I registered myself with the rss2json service and made sure this solution actually works (you can see the data in console).

The issue you have is that you are not using a proper way to form http request with HttpParams.

Here is working stackblitz that uses my key: https://stackblitz.com/edit/ionic-jdwqjg

now some details:

• when you configure a URL using rss2json it basically adds parameters to the original URL, example:

https://api.rss2json.com/v1/api.json?rss_url=https%3A%2F%2Ftechcrunch.com%2Ffeed%2F&api_key=q5ijkolkdjk3urzrcfaehxeoimxr3tdu5ieiqcrq&order_by=pubDate&order_dir=asc&count=20

• So in Angular/Ionic you need to leverage Angular's HttpParams to properly form request, here is your provider code with HttpParams:

provider code:

import { Injectable } from '@angular/core';
import { HttpClient, HttpParams } from '@angular/common/http';

@Injectable()
export class RssProvider {

  private API_URL: string;

  constructor(public http: HttpClient) {
    this.API_URL = "https://api.rss2json.com/v1/api.json";
  }

  GetRSS() {
    const params = { params: new HttpParams().set('rss_url', 'http://rss.cnn.com/rss/edition.rss').set('api_key','q5ijkolkdjk3urzrcfaehxeoimxr3tdu5ieiqcrq').set('order_by', 'pubDate').set('order_dir', 'asc')
    }
    return this.http.get(this.API_URL, params);
  }

}
