1.在src/下新建api文件夹，api/下新建index.js和public.js
在public.js中：
import axios from 'axios'; import qs from 'qs' import router from '../router' import { MessageBox} from 'mint-ui' // 注意点,按照以下写 var instance = axios.create(); instance.defaults.timeout = 10000; instance.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'; export default { fetchGet(url, params = {}) { return new Promise((resolve, reject) => { axios.get(url, params).then(res => { if(res.data.code === 302) { MessageBox('提示', '登录失效,请重新登录'); MessageBox.alert('登录失效,请重新登录', '提示').then(action => { router.push("/login"); }); } resolve(res.data); }).catch(error => { reject(error); }) }) }, fetchPost(url, params = {}) { /* axios post请求后端接收不到参数问题： 解决方案一：有效，但是兼容性不是很好，不是所有浏览器都支持 let data = new URLSearchParams() for (var key in params) { data.append(key, params[key]) } */ // 解决方案二：使用qs模块(axios中自带),使用qs.stringify()序列化params return new Promise((resolve, reject) => { axios.post(url, qs.stringify(params)).then(res => { resolve(res.data); }).catch(error => { reject(error); }) }) } }
2.在index.js中：
import http from './public' export const getStation = (params) => { return http.fetchGet('/hydro/rest/getBelongUser', params); } export const userLogin = (params) => { return http.fetchPost("/hydro/rest/login", params); }
3.在Login.vue中调用post请求方法:
<template> <div> <h1>登录页面</h1> <input type="text" placeholder="请输入用户名" v-model="Username"> <input type="password" placeholder="请输入密码" v-model="Password"> <input type="button" value="登录" @click="toLogin"> </div> </template> <script> import {userLogin} from "../../api/index" export default { name: 'app', data() { return { Username: "", Password: "" } }, methods: { toLogin() { let params = { username: this.Username, password: this.Password }; userLogin(params).then(res => { if(res.code === 200) { this.$router.push("/home") } }) } } } </script>
#### 4.在Home.vue调用get请求方法
<template> <h1> {{stationName}} </h1> </template> <script> import {getStation} from "../../api/index" export default { data() { return{ stationName: "" } }, created() { getStation().then(res => { this.stationName = res.msg; }) } } </script>
总结
