1.在src/下新建api文件夾，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'// 注意點,按照以下寫 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', '登錄失效,請重新登錄');MessageBox.alert('登錄失效,請重新登錄', '提示').then(action => { router.push("/login");});}resolve(res.data);}).catch(error => {reject(error);})})},fetchPost(url, params = {}) {/* axios post請求后端接收不到參數問題：解決方案一：有效，但是兼容性不是很好，不是所有瀏覽器都支持let data = new URLSearchParams()for (var key in params) {data.append(key, params[key])}*/// 解決方案二：使用qs模塊(axios中自帶),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中調用post請求方法:

<template><div class="login"><h1>登錄頁面</h1><input type="text" placeholder="請輸入用戶名" v-model="Username"><input type="password" placeholder="請輸入密碼" v-model="Password"><input type="button" value="登錄" @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調用get請求方法

<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>
