本文介紹了webpack+vuex+axios 跨域請求數據的示例代碼，分享給大家，具體如下：
使用vue-li 構建 webpack項目，修改bulid/config/index.js文件
dev: { env: require('./dev.env'), port: process.env.PORT || 8080, autoOpenBrowser: true, assetsSubDirectory: 'static', assetsPublicPath: '/', proxyTable: { '/v2': { target: 'http://api.douban.com', changeOrigin: true, pathRewrite: { '^/v2': '/v2' } } }, }在action.js 中想跨域請求
設置action.js：
import axios from 'axios'export const GET_IN_THEATERS = ({ dispatch, state, commit}) => { axios({ url: '/v2/movie/in_theaters' }).then(res => { commit('in_theaters', res.data) })}組件內使用：
<template> <div class="movie-page"> <ul class="clearfix"> <movies-item v-for="(item,index) in movie_list" :key="index" :movie="item"></movies-item> </ul> </div></template><script>import {mapState, mapActions, mapGetters} from 'vuex';import MoviesItem from "./movie-item";export default { data () { return { } }, components: { MoviesItem }, computed: { ...mapState({ movie_list: state => { return state.in_theaters.subjects } }) }, methods: { }, created () { this.$store.dispatch('GET_IN_THEATERS') }, mounted () { }}</script><style lang="scss">@import "./../../assets/reset.scss";@import "./../../assets/main.scss";.movie-page{ padding: 0 rem(40);}</style>在組件內想跨域
在main.js設置：
import axios from 'axios'// 將 axios 改寫為 Vue 的原型屬性,使在其它的組件中可以使用 axiosVue.prototype.$axios = axios
在組件內設置：
<template> <div class="movie-page"> <ul class="clearfix"> <movies-item v-for="(item,index) in movie_list" :key="index" :movie="item"></movies-item> </ul> </div></template><script>import MoviesItem from "./movie-item";export default { data () { return { movie_list: [] } }, components: { MoviesItem }, computed: { }, methods: { }, created () { }, mounted () { this.$axios.get('/v2/movie/in_theaters').then(res => { this.movie_list = res.data.subjects }, res => { console.infor('error') }) }}</script><style lang="scss">@import "./../../assets/reset.scss";@import "./../../assets/main.scss";.movie-page{ padding: 0 rem(40);}</style>以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
