FastAPI接受post上传JSON对象BaseModel，python

from typing import Optional

import uvicorn
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

class Person(BaseModel):
    name: str
    desc: Optional[str] = None
    age: int
    year: Optional[int] = None


@app.post("/item")
async def create_item(p: Person):
    return p


if __name__ == '__main__':
    uvicorn.run(app=app, host="0.0.0.0", debug=True)

用postman往127.0.0.1:8000/item地址post一个json对象，注意里面有些k-v特意缺失：

如果想把Person放入到一个json的key值里面：

from typing import Optional

import uvicorn
from fastapi import FastAPI, Body
from pydantic import BaseModel

app = FastAPI()


class Person(BaseModel):
    name: str
    desc: Optional[str] = None
    age: Optional[int] = 0
    year: Optional[int] = None


@app.post("/item")
async def create_item(person: Person = Body(embed=True)):
    return person


if __name__ == '__main__':
    uvicorn.run(app=app, host="0.0.0.0", debug=True)
