这次给大家带来webpack+vuex怎么实现跨域请求数据，webpack+vuex实现跨域请求数据的注意事项有哪些，下面就是实战案例，一起来看一下。
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>
<p class="movie-page">
<ul class="clearfix">
<movies-item v-for="(item,index) in movie_list" :key="index" :movie="item"></movies-item>
</ul>
</p>
</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>
<p class="movie-page">
<ul class="clearfix">
<movies-item v-for="(item,index) in movie_list" :key="index" :movie="item"></movies-item>
</ul>
</p>
</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>相信看了本文案例你已经掌握了方法，更多精彩请关注php中文网其它相关文章！
