node.js中的process.nextTick错误？

Question

我在node.js这个非常基本的例子中得到process.nextTick错误

有人可以搞清楚吗？节点无法开始侦听端口8000吗？

# cat nodejs.js
net = require("net");
s = net.createServer();

net.on('connection', function (c) {
c.end('hello');
});

s.listen(8000);

# node nodejs.js

node.js:201
    throw e; // process.nextTick error, or 'error' event on first tick
          ^
TypeError: Object #<Object> has no method 'on'

Answer 1

在Ryan的幻灯片中,这是一个错字!:-0

s/net.on/s.on/

Answer 2

您似乎正在尝试捕获库 ( ) 上的事件net，但您应该查看createServer 的 connectionListener 参数。试试这个：

var net = require("net");

var server = net.createServer(function (c) {
  c.end('Hello!'); // Implicitly fired on 'connection'
});

server.listen(8000);
