您正在滥用url模块。要访问当前路线，可以使用request.url，并且setHeader对象上没有request方法

这是一个可行的例子

const http = require("http");
const fs = require("fs");
const path = require("path");
const hostname = "127.0.0.1";
const port = 3001;
let server = http.createServer((request, response) => {
  if (request.url === "/index" || request.url === "/") {
    fs.readFile(path.join(__dirname, "index.html"), "utf8", (err, data) => {
      if (err) throw err;
      response.writeHead(200, { "Content-Type": "text/html" });
      response.end(data);
    });
  } else if (request.url === "/contact") {
    fs.readFile(path.join(__dirname, "contact.html"), "utf8", (err, data) => {
      if (err) throw err;
      response.writeHead(200, { "Content-Type": "text/html" });
      response.end(data);
      response.end(data);
    });
  } else if (request.url === "/about") {
    fs.readFile(path.join(__dirname, "about.html"), "utf8", (err, data) => {
      if (err) throw err;
      response.writeHead(200, { "Content-Type": "text/html" });
      response.end(data);
      response.end(data);
    });
  } else if (request.url === "/profile") {
    fs.readFile(path.join(__dirname, "profile.html"), "utf8", (err, data) => {
      if (err) throw err;
      response.writeHead(200, { "Content-Type": "text/html" });
      response.end(data);
      response.end(data);
    });
  } else if (request.url === "/service") {
    fs.readFile(path.join(__dirname, "service.html"), "utf8", (err, data) => {
      if (err) throw err;
      response.writeHead(200, { "Content-Type": "text/html" });
      response.end(data);
      response.end(data);
    });
  }
});

server.listen(port, hostname, () => {
  console.log(`server is started at http://${hostname}:${port}`);
});
