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>
