vue3.0引用axios

安装axios 

npm install axios -S 

main.js 配置

import axios from 'axios'
//基础配置
axios.defaults.baseURL = "https://localhost:44324/";

const app = createApp(App)
app.config.globalProperties.$http =axios
app.use(naive).use(store).use(router).mount('#app')

页面用法

 const { proxy } = getCurrentInstance();

 let login = ()=>{
      proxy.$http.get('Api/values').then((res) => {
        console.log(res)
      });
    }
