正在尝试从server.js作用域之外的文件夹检索所有图像

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

const folderPath = '/path/to/folder'; // 替换为实际的文件夹路径

function retrieveImagesFromFolder(folderPath) {
  const imagePaths = [];

  const files = fs.readdirSync(folderPath);
  files.forEach((file) => {
    const filePath = path.join(folderPath, file);
    const stats = fs.statSync(filePath);
    if (stats.isFile() && isImageFile(file)) {
      imagePaths.push(filePath);
    }
  });

  return imagePaths;
}

function isImageFile(file) {
  const imageExtensions = ['.jpg', '.jpeg', '.png', '.gif']; // 可根据需要添加其他图像文件扩展名
  const ext = path.extname(file).toLowerCase();
  return imageExtensions.includes(ext);
}

const images = retrieveImagesFromFolder(folderPath);
console.log(images);
