vue中多个组件调用同一个接口

export function getData(callback){
    let opt = {
        method : 'get',
        url: '/user',
        success: res => {
            callback(res.data.value || [])
        },
        fail:err => {
            tipInfo(err.data.desc,"提示",'warning')
        }
    }
   $http(opt)

}
getData(data => {
    console.log(data)
})
