批量替换文件名称中的非法字符nodejs脚本

批量替换文件名称中的非法字符nodejs脚本

var fs = require('fs');
const path = require('path');

//非法字符
const invalidchar = `~!@#$%^&*，。；‘’\\{【】[]}|`;

//处理非法文件名称
function process_invalid_char_in_filename(root) {
    files = fs.readdirSync(root);

    files.forEach(function(file) {
        let validfilename = []; //合法字符
        for (var i = 0; i < file.length; i++) {
            if (invalidchar.indexOf(file[i]) != -1) { //非法字符判断
                validfilename.push('x')
            } else {
                validfilename.push(file[i])
            }
        }

        var pathname = path.join(root, file),
            stat = fs.lstatSync(pathname);

        if (stat.isDirectory()) {
            //递归调用
            process_invalid_char_in_filename(pathname)
        } else {

            if (validfilename.join('') != file) { //重命名
                console.log(`${file}含有非法字符,建议新名称:${validfilename.join('')}`);
                fs.rename(path.join(root, file), path.join(root, validfilename.join('')), function(err) {
                    if (err) {
                        console.log(err);
                        throw err;
                    }
                })
            }
        }
