javascript - Node 'net' 模块 ECONNREFUSED 错误

Question

我正在查看此页面:http://nodejs.org/api/net.html#net_net_createconnection_options_connectionlistener

从页面运行代码:

var net = require('net');
var client = net.connect({port: 8124},
    function() { //'connect' listener
  console.log('client connected');
  client.write('world!\r\n');
});
client.on('data', function(data) {
  console.log(data.toString());
  client.end();
});
client.on('end', function() {
  console.log('client disconnected');
});

我收到错误:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: connect ECONNREFUSED
    at errnoException (net.js:901:11)
    at Object.afterConnect [as oncomplete] (net.js:892:19)

shell returned 8

版本内容:

我尝试了很多不同的端口，我确定 Node 还没有运行

您尝试连接的网络服务器是否正在运行？

我试过了，它对我有用:

网络.js

var net = require('net');

var server = net.createServer(function(client) {
    console.log('connected');
});

server.listen(8124);

var client = net.connect({port: 8124}, function() {
    console.log('client connected');
    client.write('world!\r\n');
});
client.on('data', function(data) {
    console.log(data.toString());
    client.end();
});
client.on('end', function() {
    console.log('client disconnected');
});

运行:

$ node net.js 
connected
client connected
