* `allow_origins` - 一个允许跨域请求的源列表。例如 `['https://example.org', 'https://www.example.org']`。你可以使用 `['*']` 允许任何源。
* `allow_origin_regex` - 一个正则表达式字符串，匹配的源允许跨域请求。例如 `'https://.*\.example\.org'`。
* `allow_methods` - 一个允许跨域请求的 HTTP 方法列表。默认为 `['GET']`。你可以使用 `['*']` 来允许所有标准方法。
* `allow_headers` - 一个允许跨域请求的 HTTP 请求头列表。默认为 `[]`。你可以使用 `['*']` 允许所有的请求头。`Accept`、`Accept-Language`、`Content-Language` 以及 `Content-Type` 请求头总是允许 CORS 请求。
