我一直在使用Cloudinary相当一段时间了，现在有一个类似的查询，你关于批量上传。据我所知，你不能通过一个请求将多个资产上传到Cloudinary。但是，您可以使用循环来改进当前代码，以避免代码重复。
如果你想上传的所有图片都在一个目录下，你可以运行下面的Node.js代码：

// Import packages
const fs = require('fs');
const cloudinary = require('cloudinary').v2;

// Replace with your credentials to configure Cloudinary
cloudinary.config({
  cloud_name: "cloud",
  api_key: "key",
  api_secret: "secret"
});

// Function to upload multiple images
const uploadMultipleImages = async (directoryPath, batchID) => {
  try {
    const fileNames = await fs.promises.readdir(directoryPath); // Read the file names from the specified directory

    const uploadResults = await Promise.all(
      fileNames.map(async (fileName) => {
        const imagePath = `${directoryPath}/${fileName}`; // Build the full path of each image file
        return cloudinary.uploader.upload(imagePath, {
          use_filename: true,
          tags: `batch ${batchID}` // Add a tag to identify the batch of uploaded images
        });
      })
    );

    // Process the upload results
    uploadResults.forEach((result) => {
      console.log(`Image uploaded with public ID: ${result.public_id}`);
      console.log(`Image URL: ${result.secure_url}`);
      console.log('----------------------');
    });
  } catch (error) {
    console.error('Error:', error);
  }
};

// Usage example
const directoryPath = 'asset_directory';
const batchID = 1;
uploadMultipleImages(directoryPath, batchID);

正如上面的代码所做的那样，我觉得用批号标记一组上传总是很有帮助的，这样可以在Cloudinary媒体库中更容易地跟踪。

没有办法批量上传图像，但我找到了一个合适的方法来避免代码重复。
在这里，所有你需要创建一个函数，它是适合保存在其他文件，然后导入

const uploadImage = async (req, id, folder, title) => {
  const image = await cloudinary.uploader.upload(req.files[id].tempFilePath, {
    public_id: `${title}`,
    use_filename: true,
    folder: `${folder}`,
  });
  fs.unlinkSync(req.files[id].tempFilePath);
  return image;
};

每当你想上传一张图片时，只需调用函数并给予函数一个名字，因为你需要一个图片的URL

const thumbnail = await uploadImage(
    req,
    "thumbnail",
    "Vehicles",
    `Vehicle thumbnail`
  );

您可以访问图像链接如下

thumbnail = thumbnail.secure_url;
