Angular 2: How to access an HTTP response body?

Both Request and Response extend Body.To get the contents, use the text() method.

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10')    .subscribe(response => console.log(response.text()))

That API was deprecated in Angular 5. The new HttpResponse<T> class instead has a .body() method. With a {responseType: 'text'} that should return a String.

Here is an example to access response body using angular2 built in Response

import { Injectable } from '@angular/core';import {Http,Response} from '@angular/http';@Injectable()export class SampleService {  constructor(private http:Http) { }  getData(){    this.http.get(url)   .map((res:Response) => (       res.json() //Convert response to JSON       //OR       res.text() //Convert response to a string   ))   .subscribe(data => {console.log(data)})  }}

Here is an example of a get http call:

this.http  .get('http://thecatapi.com/api/images/get?format=html&results_per_page=10')  .map(this.extractData)  .catch(this.handleError);private extractData(res: Response) {   let body = res.text();  // If response is a JSON use json()   if (body) {       return body.data || body;    } else {       return {};    }}private 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);}

Note .get() instead of .request().

I wanted to also provide you extra extractData and handleError methods in case you need them and you don't have them.
