1.axios官方中文说明

2.axios官方文档

3.axios和vue-resource

4.引入全局

Vue.prototype.$http = axios可以全局使用，例如：

import Vue from 'vue'import router from './router/router.js'import store from './store/store.js'import axios from 'axios'Vue.prototype.$http = axiosimport VueLazyload from 'vue-lazyload'Vue.use(VueLazyload)const app = new Vue({  router,  store}).$mount('#app')export default app

methods: {      getDataCart () {        console.log(this.$route.params.id)        this.$http({          url: '/api/goods/detail',          method: 'GET',          params: {            brand_id: this.$route.params.id          }        })          .then((res) => {            let data = res.data            console.log(data)            if (data.code === 200) {              // 合并字段 cart_num              this.detailData = Object.assign(this.detailData, data.data)            } else {              console.log(data.msg)            }          })      },
