修复前端文件上传时文件对象未正确传递的问题。 问题根源： 错误信息显示 "Expected UploadFile, received: <class 'str'>, input: undefined"， 说明 file 字段传递的不是有效的文件对象。 原因分析： 在 Ant Design Upload 组件中使用 beforeUpload 返回 false 时， fileList[0].originFileObj 可能为 undefined，导致传递了 undefined 到 FormData。 解决方案： 1. 添加 fallback 逻辑：const file = fileList[0].originFileObj || fileList[0] 2. 添加文件对象有效性检查，确保是 File 或 Blob 实例 3. 提供清晰的错误提示"无效的文件对象" 这样可以确保： - 兼容不同版本的 Ant Design Upload 组件 - 文件对象始终是有效的 File/Blob 实例 - 用户得到明确的错误反馈 Co-authored-by: multica-agent <github@multica.ai>
