阅读使用JavaScript的二进制文件，并转换为charecter

我试图读取一个二进制文件，并试图将其转换为字符
这里是代码
我不确定这是一个合适的方式
专家请纠正我

var fs = require('fs'); fs.readFile('C:/parsing/test.prn', function (err, data) { bufferString = data.toString(); bufferStringSplit = bufferString.split('\n'); var byteArray = getBytes(bufferStringSplit[50]); // converting to byte array console.log(byteArray.length) var result1 = ""; for (var i = 0; i < byteArray.length; i++) { console.log(byteArray[i],"-----------------byte array") result1 += String.fromCharCode(parseInt(byteArray[i], 2)); // converting to charecter } }); function getBytes(str) { var bytes = [], char; str = encodeURI(str); while (str.length) { char = str.slice(0, 1); str = str.slice(1); if ('%' !== char) { bytes.push(char.charCodeAt(0)); } else { char = str.slice(0, 2); str = str.slice(2); bytes.push(parseInt(char, 16)); } } return bytes; }; 

我使用的另一个代码

 var fs = require('fs'); fs.open('C:/parsing/test.prn', 'r', function(err, fd) { var result =""; if (err) throw err; var buffer = new Buffer(100); while (true) { var num = fs.readSync(fd, buffer, 0, 1, null); if (num === 0) break; console.log('byte read', buffer[0]); result += String.fromCharCode(parseInt(buffer[0], 2)); } console.log(result) }); 

console.log(result)打印如下
