本节接上一篇博客:前后端分离之Java后端
代码:/jimolonely/vue-jwt-demo
前言
前端用什么框架都可以,这里选择小巧的vuejs。
要实现的功能很简单:
1、登录功能,成功将服务器返回的token存在本地
2、使用带token的header访问服务器的一个资源
本次实验环境:
"dependencies": {
"vue": "^2.2.1"
},
"devDependencies": {
"babel-core": "^6.0.0",
"babel-loader": "^6.0.0",
"babel-preset-latest": "^6.0.0",
"cross-env": "^3.0.0",
"css-loader": "^0.25.0",
"file-loader": "^0.9.0",
"vue-loader": "^11.1.4",
"vue-template-compiler": "^2.2.1",
"webpack": "^2.2.0",
"webpack-dev-server": "^2.2.0"
}
开发IDE:Atom
首先建一个项目
使用webpack构建
/Atom# vue init webpack-simple vue-jwt-demo
...
/Atom# cd vue-jwt-demo/
/Atom/vue-jwt-demo# cnpm install
/Atom/vue-jwt-demo# npm run dev
安装插件
/Atom/vue-jwt-demo# cnpm install vue-router
/Atom/vue-jwt-demo# cnpm install vue-resource
整体目录
完成token的存取
const SERVER_URL = 'http://localhost:8081'
const LOGIN_URL = SERVER_URL+'/login2'
export default{
data:{
authenticated:false
},
login(context,info){
context.$(LOGIN_URL,info).then(function(data){
()
('token',);
this.authenticated = true
//跳到home页
this.$('home')
},function(err){
(err+","+)
=
})
},
getAuthHeader(){
return {
'Authorization':'Bearer '+('token')
}
},
checkAuth(){
var token = ('token')
if(token){
this.authenticated = true
}else{
this.authenticated = false
}
}
}
程序入口:完成路由和初始化
import Vue from 'vue'
import App from './'
import Login from './component/'
import Home from './component/'
import VueRouter from 'vue-router'
import VueResource from 'vue-resource'
import auth from './auth/auth'
(VueRouter)
(VueResource)
//在启动APP时进行校验是否有token
()
const routes= [
{
path:'/',redirect:'/login'
},
{
path:'/login',component:Login
},
{
path:'/home',component:Home
}
]
const router = new VueRouter({
routes
})
new Vue({
router,
render: h => h(App)
}).$mount('#app')
页面载体
<template>
<div id="app">
<h1>{{msg}}</h1>
<router-view></router-view>
</div>
</template>
<script>
export default {
name: 'app',
data () {
return {
msg: 'Vue前后端分离demo'
}
}
}
</script>
登录页面
<template>
<div>
<h2>登录</h2>
<p>{{ error }}</p>
<div>
<input
type="text"
placeholder="Enter your username"
v-model=""
>
</div>
<div>
<input
type="password"
placeholder="Enter your password"
v-model=""
>
</div>
<button @click="submit()">登录</button>
</div>
</template>
<script>
import auth from '../auth/auth'
export default {
data() {
return {
info: {
username: '',
password: ''
},
error: ''
}
},
methods: {
submit() {
var info = {
username: this.,
password: this.
}
(this, info)
}
}
}
</script>
效果:丑是丑了点
主页面,访问一个获取邮箱的请求
<template>
<div id="home">
<h1>{{msg}}</h1>
<button @click="getEmail()">Get Email</button>
<h2>Email:{{email}}</h2>
</div>
</template>
<script>
import auth from '../auth/auth'
export default {
name: 'home',
data () {
return {
msg: '欢迎您登录成功',
email:''
}
},
beforeCreate(){
//如果没有token的话需要重新登录
if(!){
this.$('login')
}
},
methods:{
getEmail(){
this.$('http://localhost:8081/user/getEmail',{
headers:()
}).then(function(re){
this.email =
},function(){
("get email error")
})
}
}
}
</script>
<style>
#app {
font-family: 'Avenir', Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
h1, h2 {
font-weight: normal;
}
a {
color: #42b983;
}
</style>
对应在服务端:
@GetMapping("/getEmail")
public String getEmail() {
return "xxxx@";
}
可看到浏览器的本地存储:
