类似于websocket API的一个实现，采用HTTP的方式。可用于浏览器和Node环境。
var http = require('http') var through = require('through2') var url = require('url') var Router = require("routes-router") var HTTPSocket = require('./') var HTTPSocketBackend = require('./backend') var debug = require('debug')('HTTPSocketTestServer') var backends = {} var router = Router() var server = http.createServer(router) router.addRoute("/:id/push", function (req, res, opts) { debug(req.method, req.url) var backend = backends[opts.params.id] if (!backend) backend = backends[opts.params.id] = HTTPSocketBackend() backend.post(req, res) }) router.addRoute("/:id/events", function (req, res, opts) { debug(req.method, req.url) var backend = backends[opts.params.id] if (!backend) backend = backends[opts.params.id] = HTTPSocketBackend() backend.events.pipe(res, {end: false}) req.on('close', function() { backend.events.destroy() res.end() }) }) router.addRoute("/:id/get/:object", function (req, res, opts) { debug(req.method, req.url) var backend = backends[opts.params.id] if (!backend) return res.end('no backend for that id') backend.get(opts.params.object, res) }) server.listen(8080, function listening() { var client = new HTTPSocket('http://localhost:8080') console.log('socket send', ["hello"]) client.write(new Buffer('hello')) console.log('socket send', ["world"]) client.write(new Buffer('world')) var pending = 2 client.pipe(through(function(chunk, enc, next) { console.log('socket receive', [chunk.toString()]) next() if (!--pending) { client.end() server.close() } })) })
