我总是出错，不知道出了什么问题。我正在尝试通过 Mongoose 上传多个文件。我是新来的，任何帮助都将不胜感激，谢谢。
这是我的app.js

const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, __dirname + '/uploads')
  },
  filename: function (req, file, cb) {
    const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1E9)
    cb(null, file.fieldname + '-' + uniqueSuffix)
  }
})
const upload = multer({ storage: storage })

个字符
HTML（.ejs文件）

<form action="/movies" enctype="multipart/form-data" method="POST">
  <label for="title">Title:</label>
  <input type="text" name="postTitle" required>
    
  <label for="postImages">Choose file(s):</label>
  <input type="file" name="postImages" accept="image/*" multiple>      
    
  <label for="content">Content:</label>
  <textarea name="postContent" rows="8" required></textarea>
    
  <input type="submit" value="Submit">
</form>

架构

const mongoose = require('mongoose');

const imageSchema = new mongoose.Schema({
  name: String,
  alt: String,
  image:
  {
      data: Buffer,
      contentType: String
  }
});
const Image = mongoose.model('Image', imageSchema);
module.exports = {
  Image
};
