FastAPI depends on Pydantic and Starlette. standardDependencies¶ When you install FastAPI withpip install "fastapi[standard]"it comes with thestandardgroup of optional dependencies: Used by Pydantic: email-validator- for email validation. Used by Starlette: ...

limit 并传给 common_parameters# 然后将 common_parameters 的返回值赋给 commons# 但如果解析不到某个参数,那么会判断函数中参数是否有默认值# 没有的话就会返回错误return commons@app.get("/users/")async def read_users(commons: dict = Depends(common_parameters)):return commonsif __name__ == "__...

FastAPI provides Depends class and its object is used as a common parameter in such cases. First import Depends from FastAPI and define a function to receive these parameters −async def dependency(id: str, name: str, age: int): return {"id": id, "name": name, "age": age} ...
It is just a standard function that can receive parameters. 它只是可以接收参数的标准功能。 It can be anasync defor normaldeffunction,FastAPIwill know how to handle it correctly. 它可以是一个async def或普通的def功能,FastAPI会知道如何正确处理它。
