Nodejs已流的形式读取文件

var fs = require("fs");
var data = '';
var readerStream = fs.createReadStream('input.txt');
readerStream.setEncoding('UTF-8');
readerStream.on('data', function(chunk) {
data += chunk;
});
readerStream.on('end', function(){
console.log(data);
});
readerStream.on('error', function(err){
console.log(error.stack);
});
console.log("execute end...");

1、假设当前目录下有input.txt，内容为：phoenixframework官网地址：www.cewan.la

2、以上代码另存为：readStream.js，在当前目录执行：node readStream.js，效果如下：
