Returns the bucket's cross-origin rules.

GET404 on successluzon

Request

Request line

GET https://<bucket>-<appid>.cos.luzon.convergecloudcos.com/?cors

Addressed at the bucket host, <bucket>-<appid>.cos.luzon.convergecloudcos.com, where <appid> is the account AppId.

Query parameters: cors. Every query parameter in the request must also be named in q-url-param-list and covered by the signature.

Behaviour

A bucket with no CORS configuration answers 404 NoSuchCORSConfiguration. That is the normal state of a new bucket, not a failure — a browser cannot read the bucket until rules are set.

Example

curl

curl -X GET \
  -H "Authorization: q-sign-algorithm=sha1&q-ak=…&q-signature=…" \
  "https://<bucket>-<appid>.cos.luzon.convergecloudcos.com/?cors"

Response — 404
