vue中axios调用接口和用node.js跨域

<script>
const API_PROXY = 'https://bird.ioliu.cn/v1/?url='
import axios from 'axios'
export default {
name: 'hello',
data () {
return {
msg: 'vue调用网易云接口',
author: '泥猴啊',
musics: []
}
},
mounted: function () {
var _this = this
axios.get(API_PROXY + 'http://music.163.com/api/playlist/detail?id=19723756')
.then(function (res) {
_this.musics = res.data.result.tracks
console.log(_this.musics)
}, function (error) {
console.log(error)
})
}
}
</script>

同样的我们新建一个Node.vue的模板和/node的路由

    {
      path: '/node',
      name: 'Node',
      component: Node
    }

index.js 完整代码

import Vue from 'vue'
import Router from 'vue-router'
import Hello from '@/components/Hello'
import Node from '@/components/Node'
import VueResource from 'vue-resource'

Vue.use(Router)
Vue.use(VueResource)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'Hello',
      component: Hello
    },
    {
      path: '/node',
      name: 'Node',
      component: Node
    }
  ]
})

设置代理

打开config/index.js 
修改proxyTable: {}部分 
修改为

    proxyTable: {
      '/api': {
        target: 'http://music.163.com/api',
        changeOrigin: true,
        pathRewrite: {
          '^/api': ''
        }
      }
    }

第一行的'/api'指的是虚拟路径 
target指的是目标地址，也就是实际api的地址 
pathRewrite规则重写

然后在代码页面修改一下请求地址

  mounted: function () {
    this.$http.get('/api/playlist/detail?id=19723756', {}, {
      headers: {

      },
      emulateJSON: true
    }).then(function (res) {
      this.musics = res.data.result.tracks
      console.log(this.musics)
    }, function (error) {
      console.log(error)
    })
  }

/api/playlist/detail?id=19723756上面的这个地址其实就等于http://localhost:8080/api+/playlist/detail?id=19723756

注意这里一定要重启一下node，因为你修改了node的配置一定要重启才能生效

在命令符窗口ctrl + c 
然后重新执行cnpm run dev 
这时候，命令窗口会提示

[HPM] Proxy created: /api  ->  http://music.163.com/api
[HPM] Proxy rewrite rule created: "^/api" ~> ""
> Starting dev server...

说明代理成功

然后访问http://localhost:8080/#/node

就能看到效果了
