      The nodes are described as follows:

      Node Name (Keyword) Parent Node Description Type Required
      CORSConfiguration None All configurations of the PUT Bucket cors request Container No

      Content of CORSConfiguration:

      Node Name (Keyword) Parent Node Description Type Required
      CORSRule CORSConfiguration A single CORS rule. You can configure up to 100 CORSRule. Container Yes

      Content of CORSRule:

      Node Name (Keyword) Parent Node Description Type Required
      AllowedOrigin CORSConfiguration.CORSRule An origin allowed. More than one AllowedOrigin can be configured for a single CORSRule.
    • You can set it to * to allow all domains (not recommended).
    • You can set it to a single domain such as http://www.example.com.
    • * can be placed in any positions, including the protocol, domain name, or port to match 0 or more characters. There can only be one *. Note that if you use *, unexpected origins might be matched.
    • Do not omit “http” or “https”, and if the port number is not the default port (HTTP: 80; HTTPS: 443), also include the port (e.g., https://example.com:8443).
      		•  string Yes
      AllowedMethod CORSConfiguration.CORSRule An HTTP method allowed, which corresponds to the Access-Control-Allow-Methods header in the response to a CORS request. More than one AllowedMethod can be configured for a single CORSRule. Enumerated values: PUT, GET, POST, DELETE, HEAD enum Yes
      AllowedHeader CORSConfiguration.CORSRule A custom HTTP header (case-insensitive) that the browser is allowed to send in a CORS request. When an OPTIONS request is sent, the browser will let the server know what custom HTTP headers will be used in the actual request. More than one AllowedHeader can be configured for a single CORSRule.
    • You can set it to * to allow all headers. To avoid missing headers, * is recommended.
    • If you don’t set it to *, every header specified in Access-Control-Request-Headers in the OPTIONS request must have a corresponding one in AllowedHeader.
      		•  string Yes
      ExposeHeader CORSConfiguration.CORSRule A CORS response header (case-insensitive) that can be exposed to the browser. More than one ExposeHeader can be configured for a single CORSRule.
    • If this parameter is not specified, the browser can only access simple response headers (Cache-Control, Content-Type, Expires, and Last-Modified) by default. Therefore, if you want the browser to access more response headers, specify them using this parameter.
    • You cannot set this parameter to *, meaning you must set it to a specific header.
    • You are advised to set this parameter according to the needs of your browser. ETag is recommended. For more information, please see the response header parts in API Documentation and Common Response Headers.
      		•  string Yes
      MaxAgeSeconds CORSConfiguration.CORSRule Validity period of the CORS configuration, in seconds. This parameter corresponds to the Access-Control-Max-Age header in the response to the CORS request. During the validity period, the browser does not have to issue more OPTIONS requests for the same request. Only one MaxAgeSeconds can be configured for a single CORSRule. integer Yes
      ID CORSConfiguration.CORSRule ID of the CORSRule. It can be used to specify a specific CORSRule when you call GET Bucket cors. You can configure only one ID for a single CORSRule at most. string No
