goacors

a cors-header middleware for goa(https://github.com/goadesign/goa)

how to use

1. first, import this from glide, or go get github.com/deadcheat/goacors

2. write your main.go generated automatically from goagen.

   service.Use(goacors.WithConfig(service, &goacors.DefaultGoaCORSConfig))
   

   or
   

   service.Use(goacors.WithConfig(service, &goacors.GoaCORSConfig{ AllowOrigins: []string{"http://example.com"}, AllowMethods: []string{goacors.GET}, }))

Intermediate Match Mode

Intermediate Match Mode is using match logic allow wildcard in host, like *.example.com.

NOTIFY

Note that using wild card is not correct for specification of CORS.
And this mode is not recommended for production use.
I implemented this for only testing.

how to use Intermediate Match Mode

To use this mode, you can use goacors.WithConfig like below,

service.Use(goacors.WithConfig(service, &goacors.GoaCORSConfig{
	AllowOrigins:     []string{"http://example.com"},
	AllowMethods:     []string{goacors.GET},
	DomainStrategy:   goacors.AllowIntermediateMatch,
}))

DomainStrategy option is added for this. default is goacors.AllowStrict and you need to change this to goacors.AllowIntermediateMatch
