如何在 node.js 中创建一个简单的套接字? [英] How to create a simple socket in node.js?

问题描述

我正在尝试创建一个虚拟套接字以用于我的一些测试

I'm trying to create a dummy socket for use in some of my tests

var net = require("net");

var s = new net.Socket();

s.on("data", function(data) {
  console.log("data received:", data);
});

s.write("hello!");

出现此错误

错误:此套接字已关闭.

Error: This socket is closed.

我也试过用

var s = new net.Socket({allowHalfOpen: true});

我做错了什么?

作为参考，完整的测试如下

For reference, the complete test looks like this

it("should say hello on connect", function(done) {

  var socket = new net.Socket();

  var client = Client.createClient({socket: socket});

  socket.on("data", function(data){
    assert.equal("hello", data);
    done();
  });

  client.connect();
  // writes "hello" to the socket
});

推荐答案

我不认为服务器处于监听状态.这是我用的..

I don't think the server is put into listening state. This what I use..

// server
require('net').createServer(function (socket) {
    console.log("connected");

    socket.on('data', function (data) {
        console.log(data.toString());
    });
})

.listen(8080);

// client
var s = require('net').Socket();
s.connect(8080);
s.write('Hello');
s.end();

仅限客户端..

var s = require('net').Socket();
s.connect(80, 'google.com');
s.write('GET http://www.google.com/ HTTP/1.1

');

s.on('data', function(d){
    console.log(d.toString());
});

s.end();
