单来说，vue-resource就像jQuery里的$.ajax，用来和后端交互数据的。可以放在created或者ready里面运行来获取或者更新数据...
vue-resource文档：https://github.com/vuejs/vue-resource/blob/master/docs/http.md
结合vue-router
data(){
return{
toplist:[],
alllist:[]
}
},
//vue-router
route:{
data({to}){
//并发请求，利用 Promise
return Promise.all([
//简写
this.$http.get('http://192.168.30.235:9999/rest/knowledge/list',{'websiteId':2,'pageSize':5,'pageNo':1,'isTop':1}),
//this.$http.get('http://192.168.30.235:9999/rest/knowledge/list',{'websiteId':2,'pageSize':20,'pageNo':1,'isTop':0})
//不简写
this.$http({
method:'GET',
url:'http://192.168.30.235:9999/rest/knowledge/list',
data:{'websiteId':2,'pageSize':20,'pageNo':1,'isTop':0},
headers: {"X-Requested-With": "XMLHttpRequest"},
emulateJSON: true
})
]).then(function(data){//es5写法
return{
toplist:data[0].data.knowledgeList,
alllist:data[1].data.knowledgeList
}
//es6写法 .then()部分
//.then(([toplist,alllist])=>({toplist,alllist}))
},function(error){
//error
})
}
}
在其他地方使用
ready(){
var that=this;
var websiteid = 2,
pagesize = 20,
pageno =1;
that.$http({
method:'GET',
url:'http://192.168.30.235:9999/rest/knowledge/list',
data:{'websiteId':websiteid,'pageSize':pagesize,'pageNo':pageno,'isTop':0}
}).then(function(data){
//赋值给alllist数组,
that.$set('alllist',data.data.knowledgeList)
})
//简写
/*that.$http.get('http://192.168.30.235:9999/knowledge/list',{'websiteId':2,'pageSize':20,'pageNo':1,'isTop':0}).then(function(response){
that.$set('alllist',response.data.knowledgeList)
})*/
}
若定义全部变量（在data（）中定义），使用$get()获取
data(){
return{
toplist:[],
alllist:[],
websiteid:2,
pagesize:20,
pageno:1
}
},
ready(){
var that=this;
that.$http({
method:'GET',
url:'http://192.168.30.235:9999/rest/knowledge/list',
//使用定义的全局变量 用$get()获取
data:{'websiteId':that.$get('websiteid'),'pageSize':that.$get('pagesize'),'pageNo':that.$get('pageno'),'isTop':0}
}).then(function(data){
//赋值给alllist数组,
that.$set('alllist',data.data.knowledgeList)
},function(error){
//error
})
}
post方式同理
将数据绑定到dom上
<ul>
<li v-for="item in alllist" v-if="item.istop == false">
<a v-link="{ name: 'getReceiptDetail',params:{knowledgeId: item.id }}">
<div class='fl know-info'>
<!-- | limit 和 | timer是filter 在后续会说到-->
<!--字段含义: -->
<p class='font-normal nomal-height'>{{item.title | limit 30 }}</p>
<p class='co9a9a9a' ><span style='margin-right: 1rem;'>{{item.viewTimes}}K</span><span>{{item.publishTime | timer }}</span></p> <!--viewTimes:有多少人查看 , publishTime:发布时间-->
</div>
<div class='fr know-img'>
<img v-bind:src=item.coverImage />
</div>
<div class='clearfix'></div>
</a>
</li>
</ul>
在vue-validator中做post示例 , 将接口请求地址定义为全局详见VUEX
