之前的同事写了一个工具,但有bug,就是在替换文件后原文件的格式变成utf8 BOM了,这种带BOM的XML在Mac下可能读取不出来,所以就需要写个工具处理一下。
其实思路比较简单,首先遍历目录,然后读取目录,将文件头三个字节去除掉,然后保存为utf-8格式的文件即可,直接上代码吧 :)
var fs = require('fs'); var path = "目标路径..";function readDirectory(dirPath) { if (fs.existsSync(dirPath)) { var files = fs.readdirSync(dirPath); files.forEach(function(file) { var filePath = dirPath + "/" + file; var stats = fs.statSync(filePath);
if (stats.isDirectory()) { console.log('n读取目录:n', filePath, "n"); readDirectory(filePath); } else if (stats.isFile()) { var buff = fs.readFileSync(filePath); if (buff[0].toString(16).toLowerCase() == "ef" && buff[1].toString(16).toLowerCase() == "bb" && buff[2].toString(16).toLowerCase() == "bf") { //EF BB BF 239 187 191 console.log('发现BOM文件:', filePath, "n");
buff = buff.slice(3); fs.writeFile(filePath, buff.toString(), "utf8"); } } });
} else { console.log('Not Found Path : ', dirPath); } }
readDirectory(path);
