1、安装vue-resource扩展: npm install vue-resource
2、在main.js中引入
import http from 'vue-resource'
3、使用方法
// 基于全局Vue对象使用http
Vue.http.get('/someUrl', [options]).then(successCallback, errorCallback);
Vue.http.post('/someUrl', [body], [options]).then(successCallback, errorCallback);// 在一个Vue实例内使用$http
this.$http.get('/someUrl', [options]).then(successCallback, errorCallback);
this.$http.post('/someUrl', [body], [options]).then(successCallback, errorCallback);
4、使用拦截器显示和隐藏loading效果 (需要用到vuex扩展,vuex使用方法戳这里)
store.js 代码
import Vue from 'vue'
import Vuex from 'vuex'Vue.use(Vuex)// 定义初始值
const state = {
isShowLoading: false
}// 获取变量值
const getters = {
isShowLoading: state => state.isShowLoading
}//定义触发状态对象方法,传入state整个对象
//在页面中触发时使用this.$store.commit('mutationName') 触发Mutations方法改变state的值
const mutations = {
setLoadingType(state, type) {
state.isShowLoading = type;
}
}//异步执行方法,传入参数context,等同于整个store
//处理Mutations中已经写好的方法 其直接触发方式是 this.$store.dispatch(actionName)
const actions = {
setLoadingType({commit}, type) {
// 调用mutations 方法
commit('setLoadingType', type)
}
}export default new Vuex.Store({
state,
mutations,
actions,
getters
})
main.js 代码
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import http from 'vue-resource'
import $ from 'jquery'
// 引入sotre.js
import store from './components/common/store.js'Vue.config.productionTip = falseVue.use(http)Vue.http.interceptors.push((request, next) => {
// 也可以再这里验证是否登录等操作
// 显示loading
store.dispatch('setLoadingType', true);
next((response) => {
// 隐藏loading
store.dispatch('setLoadingType', false);
return response
});
});/* eslint-disable no-new */
new Vue({
store,
el: '#app',
router,
render: h => h(App)
});
新建Loading.vue
<template id="loading-template" class="loading">
<div class="loading-overlay">
<div class="sk-three-bounce">
<div class="sk-child sk-bounce1"></div>
<div class="sk-child sk-bounce2"></div>
<div class="sk-child sk-bounce3"></div>
</div>
</div>
</template><script>
export default {
name: 'loading',
data () {
return {
msg: 'this.test uve'
}
}
}
</script><!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h1, h2 {
font-weight: normal;
}ul {
list-style-type: none;
padding: 0;
}li {
display: inline-block;
margin: 0 10px;
}a {
color: #42b983;
}
.loading-overlay {
content: "";
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 1000;
opacity: 1;
background: rgba(0, 0, 0, 0.5);
transition: all .6s;
}
</style>
App.vue 添加代码
<template>
<div id="app">
<div id="help">
<loading v-show="isShowLoading"></loading>
</div>
<router-link to="/Login">跳转到详情页</router-link>
<img src="./assets/logo.png">
<router-view></router-view>
</div></template>
<script>import loading from './components/Loading'
import {mapGetters} from 'vuex'
export default {
name: 'app',
components:{
loading
},
data () {
return {
}
},
//computed 实时计算 Vue检测到数据发生变动时就会执行对相应数据有引用的函数。
computed: {
...mapGetters([
'isShowLoading'
])
}
}
</script><style>
#app {
font-family: 'Avenir', Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
</style>
