다음의 인자들이 지원됩니다:

* `allow_origins` - 교차-출처 요청을 보낼 수 있는 출처의 리스트입니다. 예) `['https://example.org', 'https://www.example.org']`. 모든 출처를 허용하기 위해 `['*']` 를 사용할 수 있습니다.
* `allow_origin_regex` - 교차-출처 요청을 보낼 수 있는 출처를 정규표현식 문자열로 나타냅니다.  `'https://.*\.example\.org'`.
* `allow_methods` - 교차-출처 요청을 허용하는 HTTP 메소드의 리스트입니다. 기본값은 `['GET']` 입니다. `['*']` 을 사용하여 모든 표준 메소드들을 허용할 수 있습니다.

The following arguments are supported:

* `allow_origins` - A list of origins that should be permitted to make cross-origin requests. E.g. `['https://example.org', 'https://www.example.org']`. You can use `['*']` to allow any origin.
* `allow_origin_regex` - A regex string to match against origins that should be permitted to make cross-origin requests. e.g. `'https://.*\.example\.org'`.

#### Calico

For Calico, you must also modify the settings to allow source spoofing:

- if deployed by operator,  `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofing", "value": "Any"}]'`
- if deployed by manifest, add env `FELIX_WORKLOADSOURCESPOOFING` with value `Any` in `spec.template.spec.containers.env` for daemonset `calico-node`. (This will allow PODs with specified annotation to skip the rpf check. )

	// form http://localhost:8181/v1/data/httpapi/authz
	type opaResultAllow struct {

		} `json:"result"`

	// Handle simpler OPA responses when OPA URL is of
