从fastapi python开始
这就是我如何串我的服务器

class Server:
    def __init__(self):
        self.app = FastAPI()

    def runServer(self, host: str, port: int,is_dev:bool):
        uvicorn.run(self.app, host=host, port=port,debug=is_dev)

if __name__ == "__main__":
    server = Server()
    # read the environment variables
    host: str = os.environ['host']
    port: int = int(os.environ['port'])
    is_dev: bool = bool(os.environ['dev'])

    server.runServer(host, port, is_dev)

这ups服务器，但不运行在自动重装模式，如果我做任何更改.
即使我试过

uvicorn.run(self.app, host=host, port=port, reload=is_dev)

重载是我猜不是一个选项，从而导致服务器中断。
我甚至尝试在launch.json中传递--reload参数，但仍然不起作用

    ]
}

有什么想法吗？我错过了什么吗？
