BufferHelper 
Why?
Reason of written bufferhelper: 小心data事件里的chunk拼接.
Install it via NPM
npm install bufferhelper
Usage
var http = require('http');
var BufferHelper = require('bufferhelper');
http.createServer(function (request, response) {
var bufferHelper = new BufferHelper();
request.on("data", function (chunk) {
bufferHelper.concat(chunk);
});
request.on('end', function () {
var html = bufferHelper.toBuffer().toString();
response.writeHead(200);
response.end(html);
});
}).listen(8001);
或者更简单：
var http = require('http');
var BufferHelper = require('bufferhelper');
http.createServer(function (request, response) {
var bufferHelper = new BufferHelper();
bufferHelper.load(request, function (err, buffer) {
var html = buffer.toString();
response.writeHead(200);
response.end(html);
});
}).listen(8001);
