axios请求响应拦截器interceptor.js

importaxiosfrom"axios";

exportdefaultfunction(vm){
axios.interceptors.request.use(config=>{
consttoken=localStorage.getItem("token");
if(token){
config.headers.Authorization="Bearer"+token;
}

if(err.response.status===401){
//清空
vm.$store.dispatch("logout");
//跳转
vm.$router.push("/login");
}
returnPromise.reject(err);
});
}

路由守卫路由router.js

importVuefrom"vue";
importRouterfrom"vue-router";
importHomefrom"./views/Home.vue";
importLoginfrom"./views/Login.vue";

Vue.use(Router);

constrouter=newRouter({
mode:"history",

//routelevelcode-splitting

//whichislazy-loadedwhentherouteisvisited.
component:()=>
import(/*webpackChunkName:"about"*/"./views/About.vue")
}

});

router.beforeEach((to,from,next)=>{

//只要本地有token就认为登录了
consttoken=localStorage.getItem("token");
if(token){
next();
}else{
//未登录
next({

//中间件函数
//functionauth(req,res,next){

res.sendStatus(401)这个正确的

深入理解令牌机制

BearerToken规范
概念：描述在http访问OAuth2保护资源时如何使用令牌的规范
特点：令牌就是身份证明，无需证明令牌的所有权
具体规定：在请求头中定义Authorization

Authorization:Bearer

JsonWebToken规范
概念：令牌的具体定义方式
规定：令牌由三部分构成“头”，“载荷”，“签名”
头：包含加密算法。令牌类型等信息
载荷：包含用户信息。签发时间和过期时间等信息，base64编码
签名：根据头和载荷及秘钥加密得到的哈希串HmacSha1256

server/server.js

constKoa=require("koa");
constRouter=require("koa-router");
constjwt=require("jsonwebtoken");
constjwtAuth=require("koa-jwt");

constrouter=newRouter();
router.get("/api/login",asyncctx=>{
