next，react封装axios，http请求

import axios from 'axios';//声明一个基础接口变量1
let base_url;
//配置开发环境
if (process.env.NODE_ENV === 'development') {base_url = "http://127.0.0.1/";
}
// 配置生产环境
if (process.env.NODE_ENV === 'production') {base_url = "http://127.0.0.1/";
}
axios.defaults.baseURL = base_url;// 辅助函数：安全获取localStorage值,检测window
const getLocalStorage = () => {if (typeof window !== 'undefined') {return true;}return false;};
// 发送请求前拦载
axios.interceptors.request.use((config) => {var urlsa = config.url;var t = Date.parse(new Date()) / 1000;//时间戳if (urlsa.indexOf("?") != -1) {config.url = config.url + "&datest=" + t} else {config.url = config.url + "?datest=" + t}// 给post请求加参数if (config.data) {// 如果原本请求已经有数据（比如是JSON格式数据等情况）config.data = {...config.data,url: base_url};} else {// 如果原本请求没有数据，创建一个新的对象添加token参数config.data = { url: base_url };}if (getLocalStorage()) {config.headers.token = window.localStorage.getItem("token") ? window.localStorage.getItem("token") : "";config.headers.user = encodeURIComponent(window.localStorage.getItem("username"));}return config
}, (error) => {return Promise.reject(error)
})//发送请求返回拦载
axios.interceptors.response.use(function (response) {// 对响应数据做点什么var data = response.data;//console.log("打印请求回来")if (data.code == 2006) {if (getLocalStorage()) {window.localStorage.clear('username');//删除window.localStorage.clear('token');//删除//配置开发环境if (process.env.NODE_ENV === 'development') {window.location.href = "/login";}// 配置生产环境if (process.env.NODE_ENV === 'production') {window.location.href = "/login";}}return false;}return response;
},function (error) {return Promise.reject(error);// return false;}

使用

// use client表示客户端
"use client";
import http from '@/app/comm/http.js';http.post('/dadedadedade666',{id:121}).then((res) => {})
// app/dashboard/layout.tsx
export default function IndexLayout({ children }) {return (<div>{/* 仪表盘专属导航 */}<nav>后台导航</nav>{children} {/* 渲染 /dashboard/users 等子路由内容 */}</div>);
