How webpack+vuex implements cross-domain request data

This time I will show you how webpack vuex implements cross-domain request data, and what are the precautions for webpack vuex to implement cross-domain request data. The following is a practical case, let's take a look.

Use vue-li to build the webpack project and modify the bulid/config/index.js file

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'
    } 
   }
  },
 }

Want to make cross-domain requests in action.js

Set 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)
 })
}

Used within components:

<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>

Want to cross domain within the component

Set in main.js:

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

Set within the component:

<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>
