首先是简单的java接口代码
写了四个让前端请求的接口，以下为代码

@GetMapping("/v1/user/{username}/{password}")public Result login2(@PathVariable("username") String username, @PathVariable("password") String password){ return Result.succResult(200,username+"--"+password);}@PostMapping("/v1/user")public Result login3(@RequestBody User user){ return Result.succResult(200,"ok",user);}@PutMapping("/v1/user")public Result putUser(@RequestBody User user){ return Result.succResult(200,user);}@DeleteMapping("/v1/user/{id}")public Result delete(@PathVariable Integer id){ return Result.succResult(200,id);} |
前端请求需要在main.js中配置
import Axios from 'axios' Vue.prototype.$axios = Axios
前端请求方式如下
在调用的时候用以下方式进行请求

this.$axios.get('/api/v1/user/'+this.username+'/'+this.password) .then(data=> { alert('get//'+data.data.code); }).catch(error=> { alert(error); }); this.$axios.get('/api/v1/user',{ params: { username: this.username, password: this.password } }).then(data =>{ alert('get'+data.data.data) }).catch(error => { alert(error) }); this.$axios.put('/api/v1/user',{ id: 1, username: this.username, password: this.password }).then(data => { alert('数据password:'+data.data.data.password) alert('数据username:'+data.data.data.username) }).catch(error => { alert(error) }); this.$axios.delete('/api/v1/user/1') .then(data=> { alert('delete//'+data.data.code); }).catch(error=> { alert(error); }); this.$axios.post('/api/v1/user',{ username: this.username, password: this.password }).then(data => { alert('post'+data.data.data.password) }).catch(error => { alert(error); }); |
补充知识：vue结合axios封装form,restful,get,post四种风格请求
axios特点
1.从浏览器中创建 XMLHttpRequests
2.从 node.js 创建 http 请求
3.支持 Promise API
4.拦截请求和响应 （就是有interceptor）
5.转换请求数据和响应数据
6.取消请求
7.自动转换 JSON 数据
8.客户端支持防御 XSRF
安装

npm i axios–savenpm i qs --savenpm i element-ui --savenpm i lodash --save |
引入
1.在入口文件中引入所需插件
main.js

import Vue from 'vue'import App from './App.vue'import router from './router'import store from './store'import ElementUI from 'element-ui';import 'element-ui/lib/theme-chalk/index.css';import url from './apiUrl'import api from './apiUtil'Vue.prototype.$axios = api.generateApiMap(url);Vue.config.productionTip = falseVue.use(ElementUI);new Vue({ router, store, render: h => h(App)}).$mount('#app') |
2.新建一个util文件夹（只要存放工具类）
在util中建apiUtil.js ， apiUrl.js两个文件
apiUtil.js 封装请求体

apiUrl.js 配置所有请求路径参数
其中resetful风格请求的路径中的请求字段必须写在 ‘{}'中

const host= '/api' //反向代理export default { userAdd:{ url: host + "/user/add", method:"post" }, userList:{ url: host + "/user/userList", method:"get" }, userInfo:{ url: host + "/user/userInfo/{id}/{name}", method:"resetful"}, userInsert:{ url: host + "/login", method:"form"},} |
使用
四种请求方式的入参统一都以object形式传入

<template> <div class="login"> <el-button type="primary" @click="submitForm" class="submit_btn">登录</el-button> </div></template><script>export default { data() { return { }; }, methods:{ submitForm(){ this.$axios.userAdd({ id:'123', name:'liyang' }).then(data=>{ console.log(data) }) } }};</script> |
ps：入参也可以再请求interceptors.request中封装
以上这篇vue 调用 RESTful风格接口操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
