大模型读取本地文件，必须上传对象存储获取文件URL地址才行么

想说的是如果文件必须上传云端获得文件链接才能给大模型处理，那本地化部署的意义就小了。

可不可以像Dify那样加一个文件读取节点呀，获取文件链接太麻烦了，而且有数据风险，不符合本地化的初衷？

No files, tests, or entry points are named. First locate the workflow node implementation and the local file-handling path, then review how model inputs currently require object-storage URLs. Done means a documented and tested local-file route exists without requiring cloud upload.
