Bagaimana Mengendalikan Muat Naik Fail dan Data JSON Secara Serentak dalam Permintaan FastAPI POST?

Bagaimana untuk menambah kedua-dua fail dan badan JSON dalam permintaan FastAPI POST?

Kaedah 1: Menggunakan Fail dan Borang

from fastapi import FastAPI, UploadFile, File, Form

app = FastAPI()

@app.post("/data")
async def data(dataConfiguration: DataConfiguration,
               csvFile: UploadFile = File(...)):
    pass

Kaedah 2 : Menggunakan model Pydantic dan Ketergantungan

from fastapi import Form, File, UploadFile, FastAPI, Depends
from typing import List, Optional
from fastapi.responses import HTMLResponse
from pydantic import BaseModel
from fastapi.templating import Jinja2Templates

app = FastAPI()
templates = Jinja2Templates(directory="templates")

class Base(BaseModel):
    name: str
    point: Optional[float] = None
    is_accepted: Optional[bool] = False

def checker(data: str = Form(...)):
    try:
        return Base.model_validate_json(data)
    except ValidationError as e:
        raise HTTPException(
            detail=jsonable_encoder(e.errors()),
            status_code=status.HTTP_422_UNPROCESSABLE_ENTITY,
        )

@app.post("/submit")
def submit(base: Base = Depends(checker), files: List[UploadFile] = File(...)):
    return {"JSON Payload": base, "Filenames": [file.filename for file in files]}

Kaedah 3: Menggunakan Borang data sebagai rentetan JSON tunggal

from fastapi import FastAPI, status, Form, UploadFile, File, Depends, Request
from pydantic import BaseModel, ValidationError
from fastapi.exceptions import HTTPException
from fastapi.encoders import jsonable_encoder
from typing import Optional, List
from fastapi.templating import Jinja2Templates
from fastapi.responses import HTMLResponse

app = FastAPI()
templates = Jinja2Templates(directory="templates")

class Base(BaseModel):
    name: str
    point: Optional[float] = None
    is_accepted: Optional[bool] = False

def checker(data: str = Form(...)):
    try:
        return Base.model_validate_json(data)
    except ValidationError as e:
        raise HTTPException(
            detail=jsonable_encoder(e.errors()),
            status_code=status.HTTP_422_UNPROCESSABLE_ENTITY,
        )

@app.post("/submit")
def submit(base: Base = Depends(checker), files: List[UploadFile] = File(...)):
    return {"JSON Payload": base, "Filenames": [file.filename for file in files]}
