浏览之前，倡议先看这个参考文档：python 如何查看一个函数的参数

如果是其余的呢？
比方如何给 Depends 传递的是：

class？
classs instance？

from typing import Any, Optional, List
import uvicorn
from fastapi import FastAPI, Form, Query, Depends
from fastapi import Depends

app = FastAPI()


class AddressFilter():
    def __init__(self, school: str | None = None) -> None:
        pass


@app.get('/')
async def list_object(address_filter: AddressFilter = Depends(AddressFilter),
):
    return {}


if __name__ == "__main__":

    uvicorn.run(
        app='api:app',
        host="127.0.0.1",
        port=9950,
        workers=1,
        reload=True
    )

把须要让 openAPI 显示的字段，增加在 class 的 __init__ 中

from typing import Any, Optional, List
import uvicorn
from fastapi import FastAPI, Form, Query, Depends
from fastapi import Depends

app = FastAPI()


class AddressFilter():
    def __call__(self, school: str | None = None, grade: int = 1) -> None:
        pass


af = AddressFilter()


@app.get('/')
async def list_object(address_filter: AddressFilter = Depends(af),
):
    return {}


if __name__ == "__main__":

    uvicorn.run(
        app='api:app',
        host="127.0.0.1",
        port=9950,
        workers=1,
        reload=True
    )

把须要让 openAPI 显示的字段，增加在 class instance 的 __call__ 中

仍然能够失常显示
