在src文件夹下创建utils文件夹
同时在文件夹下创建request.js和auth.js文件
request.js为请求拦截、请求数据封装主入口
auth.js为设置token和删除token及判断用户是否登录封装主入口
auth.js (封装token)
export function isLogin() { if (localStorage.getItem('token')) { return true; } else { return false; } } export function getToken() { return localStorage.getItem('token'); } export function setToken(token) { localStorage.setItem('token', token); } export function removeToken() { localStorage.removeItem('token'); }
下载axios(命令: npm install axios --save-dev)、同时引入axios、getToken
import axios from 'axios'; import { getToken } from './auth';
创建实例：传两个参数（timeout（超时时间）、baseUrl（服务器路径））
const instance = axios.create({ timeout: 5000, baseURL: 'https://xxxxxxxxx/xxxx/', });
请求拦截
// 请求拦截 instance.interceptors.request.use( function(config) { // eslint-disable-next-line prettier/prettier config.headers.authorization = 'Bearer ' + getToken(); return config; }, function(error) { // Do something with request error return Promise.reject(error); } ); instance.interceptors.response.use( response => { return response; }, error => { if (error.response.status == 401) { window.location.href = '/#/login'; } if (error.response.status == 404) { window.location.href = '/404.html'; } return Promise.reject(error.response.data); } );
请求封装
/** * 获取数据 get请求 * @param {*} url * @param {*} config */ export const get = (url, config) => instance.get(url, config); /** * post请求 * @param {*} url * @param {*} data * @param {*} config */ export const post = (url, data) => instance.post(url, data); /** * put * @param {*} url * @param {*} data * @param {*} config */ export const put = (url, data, config) => instance.put(url, data, config); /** * delete * @param {*} url * @param {*} config */ export const remove = (url, config) => instance.delete(url, config);
