【js http client 封装】

client

调用client

// test.js
import http from "./http.js";

const api = new http('https://www.baidu.com');
const resp = await api.get('/');
console.log(resp.data);

const resp_login = await api.post('/user/login/', {'username': 'username', 'password': 'password'});
console.log(resp_login.status);
console.log(resp_login.data);
// console.log(resp_login.headers);
// console.log(resp_login.data);
