Node.js 将流式缓冲区转换回数字？

我有一个可读流的实现，它生成200个1-200之间的随机数：

/*
Readable that produces a list of 200 random numbers
*/
var stream = require('stream');

function Random(options) {
    // Inherits from stream.Readable
    stream.Readable.call(this, options);
    this._counter = 1;
};

Random.prototype = Object.create(stream.Readable.prototype);
Random.prototype.constructor = stream.Readable;

// Called whenever data is required from the stream
Random.prototype._read = function() {
    // Generate a random number between 1 and 200
    var randomNumber = Math.floor((Math.random() * 200) + 1);
    var buf = new Buffer(randomNumber, 'utf8');

    this.push(buf);
    this._counter++;
    // Generate 200 random numbers, then stop by pushing null
    if (this._counter > 200) {
        this.push(null);
    }
};

module.exports = Random;

在我的

main.js

中，我所要做的就是实例化流，并在它们进入时解码每个块。然而，我将jibberish作为我的输出——怎样才能让它打印出我所有的随机数

var Random = require('./random');

// Stream
var random = new Random();

random.on('data', function(chunk) {
    console.log(chunk.toString('utf8'))
});

啊，明白了。缓冲区构造函数需要接受字符串，而不是整数。将

buf

实例化行更改为：

var buf = new Buffer(randomNumber.toString());

成功了
