Vue中登录验证成功后保存token,并每次请求携带并验证token操作

//设置axios请求头加入token
Axios.interceptors.request.use(cOnfig=> { 
 if (config.push === '/') { 
  } else { 
   if (localStorage.getItem('token')) { 
     //在请求头加入token，名字要和后端接收请求头的token名字一样 
     config.headers.token=localStorage.getItem('token');  
   } 
  } 
   return config; 
 }, 
 error => { 
  return Promise.reject(error);
 });

//=============================
//响应回来token是否过期
Axios.interceptors.response.use(respOnse=> { 
  console.log('响应回来：'+response.data.code) 
  //和后端token失效返回码约定403 
  if (response.data.code == 403) {
    // 引用elementui message提示框  
    ElementUI.Message({  
     message: '身份已失效', 
     type: 'err'  
     });
    //清除token 
    localStorage.removeItem('token ');
    //跳转  
    router.push({name: 'login'}); 
   } else { 
     return response 
   } 
  }, 
 error => { 
  return Promise.reject(error); 
  })

router.beforeEach((to, from, next) => {
//to到哪儿 from从哪儿离开 next跳转 为空就是放行 
 if (to.path === '/') {
 //如果跳转为登录，就放行 
 next(); 
 } else {
 //取出localStorage判断
  let token = localStorage.getItem('token ');   
  if (token == null || token === '') { 
    console.log('请先登录')  
    next({name: 'login'});
   } else {
     next(); 
   } 
}});

{
 submitForm(formName) {
 this.$axios
  .post('/api/admin/login', {
  userName: this.ruleForm.userName,
  password: this.ruleForm.password
  })
  .then(successRespOnse=> {
  this.respOnseResult= JSON.stringify(successResponse.data)
  this.msg = JSON.stringify(successResponse.data.msg)
  if (successResponse.data.code === 200) {
  this.msg='';
  localStorage.setItem('userName',this.ruleForm.userName);
  //获取并存储服务器返回的AuthorizationToken信息
  var authorization=successResponse.headers['authorization'];
  localStorage.setItem('authorization',authorization);
  //登录成功跳转页面
  this.$router.push('/dashboard');
  
  }
  })
  .catch(failRespOnse=> {})
 }
 }

//自动给同一个vue项目的所有请求添加请求头
axios.interceptors.request.use(function (config) {
 let token = localStorage.getItem('authorization');
 if (token) {
 config.headers['Authorization'] = token;
 }
 return config;
})
