Question

var http = require("http");

http.createServer(function (request, response){
  response.writeHead(200, {'Content-Type': 'text/plain'});

response.end('hello suneha\n');
}).listen(8081);
console.log('server running at http://127.0.0.1:8081/');

当 运行 节点 js 程序 1

时，浏览器出现错误

Answer 1

这里是你用错名字的问题respponse应该是response.

http.createServer(function (request, response){

Answer 2

可能是其他进程正在使用 8081 端口。 我试过不同的端口号，它工作正常enter image description here
