问题描述

我只是想从我的 http:// localhost:8080 mocky.io >

但是收到此错误:

My request looking like that:

let headers = new Headers();
  headers.append('Content-Type', 'application/json');
  headers.append('Access-Control-Allow-Origin', '*');
  this.people = http.get('http://www.mocky.io/v2/5715f13a1100004d1187d9e1', { headers: headers })
    .map(response => response.json());
解决方案

Actually you should setup the header Access-Control-Allow-Origin in mocky.io.Just click on "Switch to Advanced mode" and you will see a "custom headers" input. Add Access-Control-Allow-Origin and put * as its value. Then create your mocky.io url. It should work now.
