Retrieving the bucket's CORS rules.

require "google/cloud/storage"

storage = Google::Cloud::Storage.new

bucket = storage.bucket "my-bucket"
bucket.cors.size #=> 2
rule = bucket.cors.first
rule.origin #=> ["http://example.org"]
rule.methods #=> ["GET","POST","DELETE"]
rule.headers #=> ["X-My-Custom-Header"]
rule.max_age #=> 3600

Methods

#add_rule

def add_rule(origin, methods, headers: nil, max_age: nil)

Add a CORS rule to the CORS rules for a bucket. Accepts options for setting preflight response headers. Preflight requests and responses are required if the request method and headers are not both simple methods and simple headers.

Parameters

• origin (String, Array<String>) — The origin or origins permitted for cross origin resource sharing with the bucket. Note: "*" is permitted in the list of origins, and means "any Origin".
• methods (String, Array<String>) — The list of HTTP methods permitted in cross origin resource sharing with the bucket. (GET, OPTIONS, POST, etc) Note: "*" is permitted in the list of methods, and means "any method".
• headers (String, Array<String>) (defaults to: nil) — The list of header field names to send in the Access-Control-Allow-Headers header in the preflight response. Indicates the custom request headers that may be used in the actual request.
• max_age (Integer) (defaults to: nil) — The value to send in the Access-Control-Max-Age header in the preflight response. Indicates how many seconds the results of a preflight request can be cached in a preflight result cache. The default value is 1800 (30 minutes.)

Example

require "google/cloud/storage"

storage = Google::Cloud::Storage.new

bucket = storage.create_bucket "my-bucket" do |b|
  b.cors.add_rule ["http://example.org", "https://example.org"],
                  "*",
                  headers: ["X-My-Custom-Header"],
                  max_age: 300
