The output from ``cors get`` can be redirected into a file, edited and then updated using ``cors set``. z� <B>SET</B> Sets the CORS configuration for one or more buckets. The ``cors-json-file`` specified on the command line should be a path to a local file containing a JSON-formatted CORS configuration, such as the example described above. � z a Gets or sets the Cross-Origin Resource Sharing (CORS) configuration on one or more buckets. This command is supported for buckets only, not objects. An example CORS JSON file looks like the following: [ { "origin": ["http://origin1.example.com"], "responseHeader": ["Content-Type"], "method": ["GET"], "maxAgeSeconds": 3600 } ] The above CORS configuration explicitly allows cross-origin GET requests from http://origin1.example.com and may include the Content-Type response header. The preflight request may be cached for 1 hour. Note that requests to the authenticated browser download endpoint ``storage.cloud.google.com`` do not allow CORS requests. For more information about supported endpoints for CORS, see `Cloud Storage CORS support <https://cloud.google.com/storage/docs/cross-origin#server-side-support>`_. The following (empty) CORS JSON file removes any CORS configuration for a bucket: [] The cors command has two sub-commands: z� For more info about CORS generally, see https://www.w3.org/TR/cors/.
