VUE|安装与配置axios

cd bookstore

npm install axios vue-axios -S

在main.js中:
import { createApp } from 'vue' import App from './App.vue' import router from './router' import store from './store' import axios from 'axios' import VueAxios from 'vue-axios'createApp(App).use(store).use(router).use(VueAxios,axios).mount('#app')

在项目根目录下的vue.config.js中的原始代码:
const { defineConfig } = require('@vue/cli-service') module.exports = defineConfig({ transpileDependencies: true })

需要更改为:
module.exports = { devServer: { proxy:{ ///api是后端数据接口的上下文路径 '/api':{ //这里的地址是后端数据接口的地址 target:'http://111.229.37.167/', //允许跨域 changeOrigin:true, } } } }

【VUE|安装与配置axios】接下来在main.js中为axios配置全局的baseURL默认值:
axios.defaults.baseURL = '/api'
