Angular2对预检的响应来自某些GET请求无效(重定向) [英] Angular2 Response for preflight is invalid (redirect) from some GET requests

问题描述

我正在使用Angular2，与rest API通信，并按如下方式设置标头:

I am using Angular2, Communicating with a rest API, settings the header like so:

import { Headers } from '@angular/http';

export const contentHeaders = new Headers();
contentHeaders.append('Accept', 'application/json');
contentHeaders.append('Content-Type', 'application/json');
contentHeaders.append('Authorization', localStorage.getItem('id_token'));

像items/这样的获取请求和POST请求都可以，但是当对一项进行GET请求时，例如:items/579212a6541d5626732619c3服务器响应服务器错误Response for preflight is invalid (redirect)

Get request like items/ and POST request works, but when making GET requests for one item, like: items/579212a6541d5626732619c3 the server respond with a server error Response for preflight is invalid (redirect)

我认为这些获取请求是相同的，但也许它们不是吗?有解决方案吗?

I thought those get requests are the same, but maybe they are not ? Any solutions ?

推荐答案

重定向+表示您可能正在从该特定请求中重定向.您确定在后端正确处理了商品的ID吗?

Redirect + says that you are probably being redirected from that particular request. Are you sure that the ID of item is handled correctly on a backend?
