python-3.x - 如何在 Sanic 中使用依赖注入实现 CORS

Question

我正在使用依赖注入库在 Sanic 中构建 API，并且正在尝试实现 CORS。

我试图将 Sanic 类分配给一个变量并将其CORS()传递__name__给providers.Factory.

下面的评论显示了我尝试实现 CORS 的确切行：

from sanic_cors import CORS, cross_origin # imported the Sanic_cors here

class Application(containers.DeclarativeContainer):
    """
    Application components container
    """
  # declared the app variable here and passed the Sanic class
    app = Sanic()
  # passed the variable in to CORS()
    CORS(app) 
    webapi = providers.Factory(app, __name__)

我预计运行 API 不会出错，但我在下面收到此错误：

Traceback (most recent call last):
  File "api.py", line 7, in <module>
    run_api(APP)
  File "/Users/Kassim/Documents/Projects/pythonProjects/my-app-engine/app/api_runner.py", line 8, in run_api
    web_api = application.webapi()
