关于如何向FastAPI的依赖函数添加参数

1. 通过path 或者query添加参数

from fastapi import Depends, FastAPI

app = FastAPI()

async def my_dependency_function(item_id: int):
    return {
    "item_id": item_id}


@app.get("/items/{item_id}")
async def read_item(item_id: int, my_dependency: dict = Depends(my_dependency_function):
    return my_dependency

2. 显示的说明参数来源

from fastapi import Depends, FastAPI, Path

app = FastAPI()

async def my_dependency_function(item_id: int = Path(...)):
    return {
    "item_id": item_id}


@app.get("/items/{item_id}")
async def read_item(my_dependency: dict = Depends(my_dependency_function):
    return my_dependency

3. 将request对象作为参数

async def test_parameters(request:Request):
    vv = request
    return {
    "result":"success"}

@app.get('/ellis/parameters')
async def ellis(token:str=Depends(verify_jwt),value:dict=Depends(test_parameters)):
    return value

4. 在路由层面设置dependends

items_router = APIRouter(
    prefix="/items",
    tags=["items"],
    dependencies=[Depends(my_dependency_function)],
)
