Proposal : make a synchronous form would be senseful!

[tony-is-coding]

See as the title, and if has any solution, please give me some suggest, thinks!

hey @newbie-tan , I'm not sure I get correctly what enhancement you want, but Forms are explained here: https://fastapi.tiangolo.com/tutorial/request-forms/

In this tutorial the function is async, but nothing prevents you from writing it synchronously removing the async keyword

@app.post("/login/")
def login(*, username: str = Form(...), password: str = Form(...)):
    return {"username": username}

tks, butThe reality is that my front colleagues pass the information to the backend by using the form table all the place, i want to make it easy to packaging as a native python data structure.

from starlette.request import Request
@router.post('/demo')
async def get_file(request:Request)
    form = await request.form()
    file_text = from["file"].file._file.read().decode('utf-8')
    path = "xxx"
    and so on ...
    return {"msg":"success"}

it is my solution , help it work in a synchronous project

@tony-is-coding I imagine you want to use synchronous path operations.

You can use normal def instead of async def: https://fastapi.tiangolo.com/async/

And if you use files (https://fastapi.tiangolo.com/tutorial/request-files/#uploadfile) you can access file.file to get the synchronous version.

@tony-is-coding Is the point that you want to be able to access the result of await request.form() without the await? If so, you should be able to accomplish that by defining a wrapper dependency:

async def get_form_data(request: Request):
    return await request.form()

@router.post('/demo')
def get_file(form = Depends(get_form_data)):
    file_text = form["file"].file._file.read().decode('utf-8')
    path = "xxx"
    and so on ...
    return {"msg":"success"}

FastAPI will evaluate the dependency asynchronously, then inject its result into the synchronous threadpool-based call to get_file.

Does that solve your use case @tony-is-coding ?
