func Get(origin string, next http.Handler) http.Handler

Get implements a simple read-only access control policy handling preflight and normal requests with a cache age of 10 minutes for preflight requests. Methods other than HEAD, OPTIONS, GET will return 405.

The origin parameter should be the case-insentive fully qualified origin domain to match or '*' to match any domain.

func Middleware 

func Middleware(cfg Config) func(http.Handler) http.Handler

Middleware returns a middleware that applies Config to the request.

type Config

Config parameterizes CORS behavior.

    // header, default is full access "*".
    AllowOrigin func(*http.Request) string
}
