用到的模块：
Vue: https://cn.vuejs.org/v2/guide/
Axios: http://www.axios-js.com/zh-cn/docs/
vant: https://youzan.github.io/vant/#/zh-CN/intro
可参考文章
1、接口配置
server/contactApi.js
// 统一接口管理 const CONTACT_API = { // 获取联系人列表 getContactList: { method: "get", url: "/contactList.json" } } export default CONTACT_API
2、配置全局的Http请求函数
server/http.js
import axios from "axios";
import contactApi from "./contactApi"import {Toast} from "vant"
let instance = axios.create({
baseURL: "/",
timeout: 1000 // 毫秒
})
// 包装请求方法的容器
const Http = {}
for(let key in contactApi){
let api = contactApi[key]
// async 作用，避免进入回调地狱
Http[key] = async function(data){
let response = {};
try{
response = await instanceapi.method
}catch(err){
response = err;
}
return response;
}
}
// 请求拦截器
instance.interceptors.request.use(
config => {
Toast.loading({
mask: false,
duration: 0, // 一直存在
forbidClick: true, // 禁止点击
message: "加载中..."
})
return config;
},()=>{
Toast.clear()
Toast("请求出错")
}
)
// 添加响应拦截器
instance.interceptors.response.use(
res => {
Toast.clear()
return res.data;
},()=>{
Toast.clear()
Toast("请求出错")
}
)
export default Http
3、全局挂载
main.js
// 把Http挂在到vue实例上，全局可用
Vue.prototype.$Http = Http
4、视图中调用http
views/VantIndex.vue
<template>
<div>
<!-- 联系人列表 -->
<van-contact-list :list="list" />
</div>
</template>
<script>
// 引入组件
import { ContactList } from "vant";
export default {
name: "vantIndex",
data() {
return {
list: []
};
},
// 注册组件
components: {
[ContactList.name]: ContactList
},
methods: {
async getContactList() {
let res = await this.$Http.getContactList({ name: "Tom" });
this.list = res.data;
}
},
// mounted creared
creared() {
this.getContactList();
}
};
</script>
5、修改路由
router.js
routes: [
{
path: '/',
name: 'index',
component: () => import('./views/VantIndex.vue')
}
]
6、测试数据 public/contactList.json
{
"code": 200,
"data": [
{
"name": "张三",
"tel": "13000000000",
"id": 1
},
{
"name": "李四",
"tel": "13000000001",
"id": 2
},
{
"name": "王五",
"tel": "13000000002",
"id": 3
}
]
}
启动服务访问测试
npm run serve
http://localhost:8080/
</div>
