Question

Error 404 occurs when attempting to retrieve a JSON file using Angular's HTTP

I'm having an issue with my service code. Here is the code snippet:

import {Injectable} from '@angular/core';
import {Http, Headers, RequestOptions} from '@angular/http';
import 'rxjs/add/operator/map';
import {Client} from "../clients/client";
import {Observable} from "rxjs/Observable";


@Injectable()
export class ClientsService {


  private clientUrl = './client.json';

  private headers = new Headers({ 'Accept': 'application/json' });
  private options = new RequestOptions({ headers: this.headers });

  private client : Client;

  constructor(private http:Http) {}

  getClient() : Observable<any>{
    return this.http.get(this.clientUrl, this.options)
      .map(res => res);
  }
}

In my component, I call the service like this:

this.client = this.clientsService.getClient()
  .subscribe(data => {
    console.log(data);
  });

However, I keep receiving a 404 error.

What's causing the issue? The JSON file is in the same folder as my service.

Make sure to provide the complete path starting from your base directory. For instance, use path/to/Services/client.json

When working with angular-cli, remember to store your json file in the Assets folder, located parallel to the app directory.

In your specific case, you should create a file named assets/client.json

return this.http.get('/client.json'))
    .map((response: Response) => {
        console.log("mock data" + response.json());
        return response.json();
    }
    )
    .catch(this.handleError);
}

Keep in mind that when referencing the file path inside the assets folder, only write it as assets/client.json and later refer to it as /client.json

If you are using webpack, follow the same structure within the public folder, which is similar to the assets folder.

To properly handle JSON files in your project, you will need to include the following code snippet in a file called typings.d.ts:

declare module "*.json"
{ const value: any;
  export default value;
}
declare module "json!*"
{ const value: any;
  export default value;
}

Once you have added this code, you can easily import JSON files using the statement

import * as data1 from 'path.json';
