NodeJs Http 外网访问

NodeJs 官方代码：

example.js http

var http = require(‘http‘);
http.createServer(function (req, res) {
        res.writeHead(200, {‘Content-Type‘: ‘text/plain‘});
        res.end(‘Hello World\n‘);
}).listen(9337, ‘127.0.0.1‘);
console.log(‘Server running at http://127.0.0.1:9337/‘);

example.js tcp

var net = require(‘net‘);
var server = net.createServer(function (socket) {
        socket.write(‘Echo server\r\n‘);
        socket.pipe(socket);
});
server.listen(9337, ‘127.0.0.1‘);

运行

node example.js

访问

http://127.0.0.1:9337/

如果部署在服务器，需要外网访问，把127.0.0.1改为对应服务器的IP地址，对应的防火墙端口开放出来 就好了
