axios请求拦截器和相应拦截器

//请求拦截器
axios.interceptors.request.use(
  config => {
    Vue.$vux.loading.show({
      text: '请求中'
    })
    let Token = sessionStorage.getItem('token')==""? "":sessionStorage.getItem('token');//判断是否是登陆状态
    if (Token){//如果登录了做超时判断，没登录不管
      let time = parseInt(new Date().getTime())-parseInt(sessionStorage.getItem('time'))
      if(time>=1800000){//未操作时间》 30分钟，token清除
        sessionStorage.setItem('token',"")
        Token = ''
      }
      if(!Token){
        if(localStorage.getItem('userName') && localStorage.getItem('userPwd')){
          router.replace({
            path: '/registered/1'  //去登陆
          })
        }
      }
    }
    config.headers['Authorization'] = Token
    return config
  },error => {
    if (error.response) {
      switch (error.response.status) {
        case 401:
          // 返回 401 清除token信息并跳转到登录页面
          sessionStorage.setItem('token',"")
          router.replace({
            path: '/registered/1'
          })
      }
    }
    return Promise.reject(error.response.data)
  })


//相应拦截器
axios.interceptors.response.use(
  response => {   //对响应数据做些事
    if(response.status >=200){
      Vue.$vux.loading.hide()
    }
  console.log("response")
  return response;
},err => {   //请求错误时做些事
return Promise.reject(err);
});
