var fs = require(‘fs‘);
var readstream = fs.createReadStream(‘./新建文本文档.txt‘);
var str=‘‘;
var iconv = require(‘iconv-lite‘);
var count=0;
readstream.on(‘data‘,function (chunk) {
    str+=iconv.decode(chunk,‘GBK‘);
    count++;
});
readstream.on(‘end‘,function () {
    console.log(str.toString());
    console.log("文件分"+count+"次读完")
});
