详解vue axios二次封装

})

return response
},error => {

})

function errorState(response) {
//隐藏loading
console.log(response)
// 如果http状态码正常，则直接返回数据
if (response && (response.status === 200 || response.status === 304 || response.status === 400)) {
return response
// 如果不需要除了data之外的数据，可以直接 return response.data
}else{
Vue.prototype.$msg.alert.show({
title: '提示',content: '网络异常'
})
}

}

function successState(res) {
//隐藏loading
//统一判断后端返回的错误码
