使用Express搭建一个简易的静态资源服务器，支持代理&跨域

const express = require("express");
const { createProxyMiddleware, responseInterceptor } = require("http-proxy-middleware");

const port = 8080;
const app = express();
app.use(
    createProxyMiddleware("/api/", {
        target: "http://example.com/api/",
        changeOrigin: true,
        pathRewrite: {
            "^/api": "",
        },
       selfHandleResponse: true, 
        onProxyRes: responseInterceptor(async (responseBuffer, proxyRes, req, res) => {
            res.removeHeader("Access-Control-Allow-Origin")
            res.setHeader("Access-Control-Allow-Origin", "*")
            return responseBuffer
     }),
    })
);
app.use(express.static("dist"));
app.listen(port);
console.log("Server is running at http://localhost:" + port);
