Example Code

from typing import Union

from fastapi import Body, FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    description: Union[str, None] = None
    price: float
    tax: Union[float, None] = None


class User(BaseModel):
    username: str
    full_name: Union[str, None] = None


@app.put("/items/{item_id}")
async def update_item(
    *,
    item_id: int,
    item: Item,
    user: User,
    importance: int = Body(gt=0),
    q: Union[str, None] = None
):
    results = {"item_id": item_id, "item": item, "user": user, "importance": importance}
    if q:
        results.update({"q": q})
    return results

Description

教程-用户指南 中的 请求体-多个参数 中的 多个请求体参数和查询参数 中的示例代码出现错误
https://fastapi.tiangolo.com/zh/tutorial/body-multiple-params/#_3

Body参数缺少一个位置参数，即TypeError: Body() missing 1 required positional argument: 'default'

个人建议改为 Body(..., gt=0),

Hi @liufei1997
Maybe you need to update the version of fastapi to 0.78.0.
See #4911 (comment)
