Everything was running smoothly with my Service until today, when I encountered the following error:
TypeError: this.http.get(...).map(...).catch is not a function.
Upon debugging the code, it crashes at the catch method.
import { Test } from "./home.component";
import { Injectable } from "@angular/core";
import { Inject } from "@angular/core";
import { Http , Response } from "@angular/http";
import { Observable } from "rxjs/Observable";
@Injectable()
export class HomeService {
public constructor(@Inject(Http) private http: Http) {}
public getData (): Observable<Test []> {
return this.http.get("./src/app/home/home-data.json")
.map(this.extractData).catch(this.handleError);
}
public extractData(res: Response) {
let body = res.json();
return body.data || { };
}
public handleError (error: any) {
// In a real world app, we might use a remote logging infrastructure
// We'd also dig deeper into the error to get a better message
let errMsg = (error.message) ? error.message :
error.status ? `${error.status} - ${error.statusText}` : "Server error";
console.error(errMsg); // log to console instead
return Observable.throw(errMsg);
}
}
