I have updated the `/file_parse` endpoint in `app.py` to correctly handle boolean and string parameters when they are sent via `multipart/form-data` requests (commonly used for file uploads). Previously, these parameters were not being properly parsed because FastAPI expects them to be passed as query or JSON body parameters by default.
### Changes Made:
- Added `Form(...)` to all non-file parameters (`parse_method`, `is_json_md_dump`, `output_dir`, and return flags like `return_layout`, etc.).
- This ensures that FastAPI correctly reads these fields from form-data, allowing clients to send both files and structured configuration options in the same request.
### Why This Change Was Needed:
- When using `requests.post(..., data=data, files=files)`, the `data` dictionary is sent as form-encoded data.
- Without explicitly declaring these fields with `Form(...)`, FastAPI does not bind them correctly, leading to default values always being used (e.g., `False` for boolean flags).
- This change allows the API to accurately reflect the client's intent and enables features like `return_layout`, `return_images`, etc., to work as expected.
This update improves compatibility with HTTP clients that rely on standard form-based file upload mechanisms while preserving the existing behavior of the API.
