使用 repl 模块搭建一个面向 curl 的 SREPL

repl-curl.js

/**
 * Requires node v0.7.7 or greater.

 * To connect: $ curl -sSNT. localhost:8000

var http = require('http')
  , repl = require('repl')

var server = http.createServer(function (req, res) {
  res.setHeader('content-type', 'multipart/octet-stream')

  res.write('Welcome to the Fun House\r\n')
  repl.start({
      prompt: 'curl repl> '
    , input: req
    , output: res

  // log
  console.log(req.headers['user-agent'])

  // hack to thread stdin and stdout
  // simultaneously in curl's single thread
  var iv = setInterval(function () {
    res.write(buf0)
  }, 100)

  res.connection.on('end', function () {
    clearInterval(iv)
