龙卷风旋转未在URL中拾取参数

Question

i具有Tornado中构建的API，我正在尝试使用tornado-swirl进行记录。由于某种原因，它无法从定义的URL中选择可选的查询参数。如何解决？我不确定我在做什么错，或者我在这里缺少什么。

我已经更改了模式，甚至使用了文档和tut。

import tornado.web
import tornado_swirl as swirl
from .base import BaseHandler
@swirl.restapi('/item/(?P<id>[w-]+)?')
class ItemHandler(BaseHandler):
    def post(self, id):
        """Item
        Creating a new item
        Tags:
            Item
        """
        # store the item
        pass
     async def get(self, id):
        """Item
        Get items or item
        Tags:
            Item
        """
        # return all items if no id was provided
        # or return item by id when provided
        pass

我会收到以下错误：

Traceback (most recent call last):
  File "/Users/.../venv/lib/python3.7/site-packages/tornado/web.py", line 1697, in _execute
    result = method(*self.path_args, **self.path_kwargs)
  File "/Users/.../venv/lib/python3.7/site-packages/tornado_swirl/views.py", line 101, in get
    for path, spec, operations in apis},
  File "/Users/.../venv/lib/python3.7/site-packages/tornado_swirl/views.py", line 100, in <dictcomp>
    'paths': {path: self.__get_api_spec(spec, operations)
  File "/Users/.../venv/lib/python3.7/site-packages/tornado_swirl/views.py", line 368, in find_api
    ['{%s}' % arg for arg in [param.name for param in vals]]
TypeError: not enough arguments for format string

显然，它没有得到争论。我认为这与我在那里定义URL有关。

您只需要告知DocString中的路径参数，类似的内容：

"""Item
Creating a new item
Path Params:
    id (string) --  Your id
Tags:
    Item
"""
