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 = {}) { // 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 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>

总结

以上所述是小编给大家介绍的Vue简单封装axios之解决post请求后端接收不到参数问题，希望对大家有所帮助！
