Python 使用自定义路径参数将路由添加到 FastAPI

这将生成一个具有新签名的函数(我假设每个参数都是一个字符串):

from fastapi import APIRouter
import re
import inspect

my_router = APIRouter()


def generate_function_signature(route_path: str):
    args = {arg: str for arg in re.findall(r'\{(.*?)\}', route_path)}
    
    def new_fn(**kwargs):
        return {"Result": kwargs['xyz']}

    params = [
        inspect.Parameter(param,
                         inspect.Parameter.POSITIONAL_OR_KEYWORD,
                         annotation=type_)
        for param, type_ in args.items()
    ]

    new_fn.__signature__ = inspect.Signature(params)
    new_fn.__annotations__ = args
    return new_fn


read_from_file = '/foo/{xyz}' # Assume this is read from a file

my_router.add_api_route(read_from_file, endpoint=generate_function_signature(read_from_file))


read_from_file = '/foo/bar/{xyz}' # Assume this is read from a file

my_router.add_api_route(read_from_file, endpoint=generate_function_signature(read_from_file))

然而，我相信有一个更好的方法来做你想做的任何事情，但我需要首先了解你的问题
