根据目录中的文件夹返回字符串

<input type="file" id="folderInput" webkitdirectory directory multiple>

var folderInput = document.getElementById('folderInput');
var folderPath = folderInput.files[0].path;

// 使用腾讯云 COS SDK
var COS = require('cos-nodejs-sdk-v5');
var cos = new COS({
    SecretId: 'your-secret-id',
    SecretKey: 'your-secret-key'
});

// 设置上传参数
var params = {
    Bucket: 'your-bucket-name',
    Region: 'your-region',
    Key: 'your-folder-key',
    Body: folderPath
};

// 上传文件夹
cos.putObject(params, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        console.log('Folder uploaded successfully');
    }
});

npm install cos-nodejs-sdk-v5

var fs = require('fs');

// 读取文件夹中的文件
var folderPath = '/path/to/folder';
fs.readdir(folderPath, function(err, files) {
    if (err) {
        console.log(err);
    } else {
        var fileNames = files.join(', '); // 将文件名拼接成字符串
        console.log(fileNames);
    }
});
