* `expose_headers` - Indicate any response headers that should be made accessible to the browser. Defaults to `[]`.
* `max_age` - Sets a maximum time in seconds for browsers to cache CORS responses. Defaults to `600`.

The middleware responds to two particular types of HTTP request...

### CORS preflight requests { #cors-preflight-requests }

* `allow_credentials` - 指示跨域请求支持 cookies。默认是 `False`。另外，允许凭证时 `allow_origins` 不能设定为 `['*']`，必须指定源。
* `expose_headers` - 指示可以被浏览器访问的响应头。默认为 `[]`。
* `max_age` - 设定浏览器缓存 CORS 响应的最长时间，单位是秒。默认为 `600`。

中间件响应两种特定类型的 HTTP 请求……

### CORS 预检请求

这是些带有 `Origin` 和 `Access-Control-Request-Method` 请求头的 `OPTIONS` 请求。

* `allow_credentials` - 교차-출처 요청시 쿠키 지원 여부를 설정합니다. 기본값은 `False` 입니다. 또한 해당 항목을 허용할 경우 `allow_origins` 는 `['*']` 로 설정할 수 없으며, 출처를 반드시 특정해야 합니다.
* `expose_headers` - 브라우저에 접근할 수 있어야 하는 모든 응답 헤더를 가리킵니다. 기본값은 `[]` 입니다.
* `max_age` - 브라우저가 CORS 응답을 캐시에 저장하는 최대 시간을 초 단위로 설정합니다. 기본값은 `600` 입니다.

미들웨어는 두가지 특정한 종류의 HTTP 요청에 응답합니다...

### CORS 사전 요청

`Origin` 및 `Access-Control-Request-Method` 헤더와 함께 전송하는 모든 `OPTIONS` 요청입니다.
