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paramsreturn 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 class="login"><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 class="home">{{stationName}}</h1></template><script>import {getStation} from "../../api/index"export default {data() {return{stationName: ""}},created() {getStation().then(res => {this.stationName = res.msg;})}}</script>
