1.在login.vue中通过发送http请求获取token
//根据api接口获取token
var url = this.HOST + "/session";
this.$axios.post(url, {
username: this.loginForm.username,
password: this.loginForm.pass
}).then(res => {
// console.log(res.data);
this.$message.success('登录成功');
let data = res.data;
//根据store中set_token方法将token保存至localStorage/sessionStorage中，data["Authentication-Token"]，获取token的value值
this.$store.commit('set_token', data["Authentication-Token"]);
if (store.state.token) {
this.$router.push('/')
console.log(store.state.token)
} else {
this.$router.replace('/login');
}
}).catch(error => {
// this.$message.error(error.status)
this.loading = false
this.loginBtn = "登录"
this.$message.error('账号或密码错误');
// console.log(error)
})
2.在store.js中对token状态进行监管
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
state:{
token:''
},
mutations:{
set_token(state, token) {
state.token = token
sessionStorage.token = token
},
del_token(state) {
state.token = ''
sessionStorage.removeItem('token')
}
}
})
3.在router/index.js中
// 页面刷新时，重新赋值token
if (sessionStorage.getItem('token')) {
store.commit('set_token', sessionStorage.getItem('token'))
}
const router = new Router({
mode: "history",
routes
});
router.beforeEach((to, from, next) => {
if (to.matched.some(r => r.meta.requireAuth)) { //这里的requireAuth为路由中定义的 meta:{requireAuth:true}，意思为：该路由添加该字段，表示进入该路由需要登陆的
if (store.state.token) {
next();
}
else {
next({
path: '/login',
query: {redirect: to.fullPath}
})
}
}
else {
next();
}
})
4.在main.js中定义全局默认配置：
Axios.defaults.headers.common['Authentication-Token'] = store.state.token;
5.在src/main.js添加拦截器
// 添加请求拦截器
Axios.interceptors.request.use(config => {
// 在发送请求之前做些什么
//判断是否存在token，如果存在将每个页面header都添加token
if(store.state.token){
config.headers.common['Authentication-Token']=store.state.token
}
return config;
}, error => {
// 对请求错误做些什么
return Promise.reject(error);
});
// http response 拦截器
Axios.interceptors.response.use(
response => {
return response;
},
error => {
if (error.response) {
switch (error.response.status) {
case 401:
this.$store.commit('del_token');
router.replace({
path: '/login',
query: {redirect: router.currentRoute.fullPath}//登录成功后跳入浏览的当前页面
})
}
}
return Promise.reject(error.response.data)
});
