Estoy tratando de aprender a usar la biblioteca Fast API. Estoy tratando de aceptar una matriz en la publicación usando frozenset como dice la documentación, pero parece que no funciona.

 import logging from fastapi import FastAPI, BackgroundTasks from worker.celery_app import celery_app log = logging.getLogger(__name__) app = FastAPI() def celery_on_message(body): """ Logs the initiation of the endpoint """ log.warn(body) def background_on_message(task): """ logs the function when it is added to queue """ log.warn(task.get(on_message=celery_on_message, propagate=False)) @app.get("/") async def root(stocks: frozenset, background_task: BackgroundTasks): """ :param stocks: stocks to be analyzed :param background_task: initiate the tasks queue :type background_task: starlette.background.BackgroundTasks :return: """ task_name = None # set correct task name based on the way you run the example log.log(level=1, msg=f'{stocks}') task_name = "app.app.worker.celery_worker.compute_stock_indicators" task = celery_app.send_task(task_name, args=[stocks]) background_task.add_task(background_on_message, task) return {"message": "Stocks analyzed"}

Cuando estoy usando los documentos de Swagger para enviar una solicitud:

 curl -X GET "http://127.0.0.1:8000/?stocks=wix&stocks=amzn" -H "accept: application/json"

la respuesta es:

 { "detail": [ { "loc": [ "query", "stocks" ], "msg": "value is not a valid frozenset", "type": "type_error.frozenset" } ] }
