axios跨域处理！

1. 使用npm安装axios插件 npm install axios

2. config目录下 index.js文件 proxyTable: {
   '/douban_api': {
   target: 'api.douban.com', //目标接口域名
   pathRewrite: {
   '^/douban_api': '' //重写接口
   },
   changeOrigin: true, //是否跨域
   },

   },

3. main.js

    import  Axios from  'axios'
    Vue.prototype.$axios=Axios      
    Vue.prototype.HOST="/douban_api"
   

4. components下 HelloWorld.vue组件

export default {

name: 'HelloWorld',
data () {
return {
msg: 'Welcome to Your Vue.js App'
}
},
mounted() {
const url=this.HOST+"/v2/movie/top250";
this.$axios.get(url)
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
}

}
