How to call FastAPI file upload route

I have written FastAPI to upload a file but in my new requirement, I have to create CLI to upload a file for that I am calling route function.

@app.post("/uploadfile/")
async def create_upload_file(file: Uploadfile =File(...));
      pd.DataFrame = pd.read_csv(file.file)
      return True

create_upload_file(file=UploadFile(input_file_path))

when i tried to read that file like : claims: pd.DataFrame = pd.read_csv(file.file) i am getting following error

No columns to parse from file

You can try reading and decoding the content from the file and then using pandas to read csv.

from io import StringIO
import pandas as pd

@app.post("/uploadfile/")
async def create_upload_file(file: Uploadfile =File(...)):
      file = StringIO((await file.read()).decode("utf-8"))
      df = pd.read_csv(file)
      return True

you can read the csv as following:

from io import BytesIO
df = pd.read_csv(BytesIO(file.file.read()))
