Add a process to fetch the mime type from the file name for signed url in remote_url

Summary

  • Fixes #10737

  • Fix the issue that the remote_url encounters an error due to the inability to retrieve the mime type when using an S3 signed URL.

  • Add a process to fetch the mime type from the file name. This method is already implemented in api/controllers/common/helpers.py.

  • Add the following line to line 172 of api/factories/file_factory.py:
    "mime_type = mime_type or mimetypes.guess_type(filename)[0]".

  • Confirmed that the MIME type is correctly retrieved in the local environment.

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. List any dependencies that are required for this change.

I think we can use this way directly and remove L169, would you mind making this change?
