Node.js 小工具
說明：把指定資料夾內的檔案、資料夾使用 7-Zip 壓縮成一個 .zip 檔，再把 .zip 檔上傳到 FTP Server，上傳成功後會使用 Outlook 2013 建立新 Email。
有用到 ftp package。
const fs = require('fs');
const path = require('path');
const { execSync } = require('child_process');
const ftpClient = require('ftp');
if (process.argv.length > 3) {
console.log('檔名請勿包含空格！');
return;
}
// 取得 .zip 檔名，預設為：YYYYMMDD-HHMMSS
const zipFileName = process.argv[2] || getDateTime();
// app
const z7 = '"C:\\Program Files\\7-Zip\\7z.exe"';
const outlook2013 = '"C:\\Program Files (x86)\\Microsoft Office\\Office15\\OUTLOOK.EXE"';
// 程式執行資料夾
const currentFolder = path.join(__dirname);
// 要被壓縮檔案、資料夾的路徑
const ftpFolder = path.join(currentFolder, 'FTP');
const fileList = fs.readdirSync(ftpFolder);
if (!fileList.length) {
console.log('FTP 資料夾內沒有檔案');
return;
}
// zip 檔輸出資料夾
const zipOutputFolder = path.join(currentFolder, 'OUTPUT');
// 如果 OUTPUT 資料夾存在，刪除
if (fs.existsSync(zipOutputFolder)) {
