Enabled the ability to use CORS for all sources
Cross-Origin Resource Sharing (CORS)

[ilyajob05]

Hi all!
I added the ability to include braids in the header; to do this, just add a flag -lets-CORS to the arguments and checked the functionality

./s3www -endpoint "https://s3-aws.com" -accessKey "KEY" -secretKey "KEY" -bucket "bucket" -address "0.0.0.0:80" -lets-CORS

If you want to enable cors add rs/cors dependency and use that handler instead.

You can also add, allowedorigins can be skipped for now, because we can take those as options

--allowed-cors-origins "http://example.com,http://example2.com"

        opts := cors.Options{
                AllowOriginFunc: func(origin string) bool {
                        if allowedCorsOrigin == "" {
                                return true
                        }
                        for _, allowedOrigin := range strings.Split(allowedCorsOrigin, ",") {
                                if wildcard.MatchSimple(allowedOrigin, origin) {
                                        return true
                                }
                        }
                        return false
                },
                AllowedMethods: []string{
                        http.MethodGet,
                        http.MethodPut,
                        http.MethodHead,
                        http.MethodPost,
                        http.MethodDelete,
                        http.MethodOptions,
                        http.MethodPatch,
                },
                AllowedHeaders:   []string{"*"},
                ExposedHeaders:   []string{"*"},
                AllowCredentials: true,
        }
        return cors.New(opts).Handler(handler)

@harshavardhana hi!
the workflow is still awaiting approval from the maintainer

[harshavardhana]

let me think about this.

Actually there is a problem we can't link this package here since minio/pkg is AGPLv3
