webpack+vuex+axios 跨域请求数据的示例代码

本文介绍了webpack+vuex+axios 跨域请求数据的示例代码，分享给大家，具体如下：

使用vue-li 构建 webpack项目，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 中想跨域请求

设置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)
 })
}

组件内使用：

<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>

在组件内想跨域

在main.js设置：

import axios from 'axios'
// 将 axios 改写为 Vue 的原型属性,使在其它的组件中可以使用 axios
Vue.prototype.$axios = axios

在组件内设置：

<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>
