下面通過(guò)一段代碼給大家介紹Vue axios全局?jǐn)r截 get請(qǐng)求、post請(qǐng)求、配置請(qǐng)求，具體代碼如下所述：
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title> <script src="../node_modules/vue/dist/vue.js"></script> <script src="../node_modules/axios/dist/axios.js"></script> <link rel="stylesheet" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous"></head><body><div id="app" class="container"> <h1>axios插件講解</h1> <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="btn btn-primary" v-on:click="get">Get請(qǐng)求</a> <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="btn btn-primary" v-on:click="post">Post請(qǐng)求</a> <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="btn btn-primary" v-on:click="http">http</a> <div> <span>{{this.msg}}</span> </div></div><script> new Vue({ el: '#app', data: { msg: '' }, mounted () { // 請(qǐng)求攔截 axios.interceptors.request.use(config => { return config },error => { return Promise.reject(error) }) axios.interceptors.response.use(response => { // 預(yù)處理相應(yīng)的數(shù)據(jù) return response }, error => { // 錯(cuò)誤返回 狀態(tài)碼驗(yàn)證 return Promise.reject(error) }) }, methods: { get () { axios.get('../package1.json', { params: { userId: '999' }, headers: { token: 'jack' } }).then(res => { this.msg = res.data }).catch(error => { console.log('error init.' + error) }) }, post () { axios.post('../package.json', { userId: '888' },{ headers: { token: 'tom' } }).then(res => { this.msg = res.data }).catch(error => { console.log('error init.' + error) }) }, http () { // 配置請(qǐng)求 axios({ url: '../package.json', method: 'get', // if method is post data: { userId: '101' }, // if method is get params: { userId: '102' }, headers: { token: 'http-test' } }).then(res => { this.msg = res.data }).catch(error => { console.log('error init.' + error) }) } } })</script></body></html>ps：下面看下vue axios數(shù)據(jù)請(qǐng)求get、post方法的使用
我們常用的有g(shù)et方法以及post方法，下面簡(jiǎn)單的介紹一下這兩種請(qǐng)求方法
vue中使用axios方法我們先安裝axios這個(gè)方法
npm install --save axios
安裝之后采用按需引入的方法，哪個(gè)頁(yè)面需要請(qǐng)求數(shù)據(jù)就在哪個(gè)頁(yè)面里引入一下。
import axios from 'axios'
引入之后我們就可以進(jìn)行數(shù)據(jù)請(qǐng)求了，在methods中創(chuàng)建一個(gè)方法
