组件应该没啥问题，使用的时候得增加一些判断，防止重复请求。
data(){
return{
isLoaded:false//以此来判断数据是否加载完了
}
},
methods:{
getNextPage(){
//只有isLoaded为false的时候才去加载数据，这样不就不会重复去请求接口了
if(!this.isLoaded){
this.isLoaded=true
//数据请求
axios.get('/api/xxx')
.then(res=>{
//请求成功了再将isLoaded变成false状态
this.isLoaded=false
})
.error(err=>{
//error同理
this.isLoaded=false
})
}
}
}
