axios拦截器

//定义一个请求拦截器
axios.interceptors.request.use(function(config){
  store.state.loading = true; //在请求发出之前进行一些操作
  setTimeout(() => {
    store.state.loading = false;
  }, 10000);
  //clearTimeout(timer)
  return config
})
//定义一个响应拦截器
axios.interceptors.response.use(function(config){
  store.state.loading = false;//在这里对返回的数据进行处理
  store.state.ressuccess=true;
  if(config.data.code === 297){
    store.state.islogin = false
  }
  return config
})
