    import (


    func main() {
    	// CORS for https://foo.* origins, allowing:
    	// - PUT and PATCH methods
    	// - Origin header
    	// - Credentials share
    	beego.InsertFilter("*", beego.BeforeRouter, cors.Allow(&cors.Options{
    		AllowOrigins:     []string{"https://*"},
    		AllowMethods:     []string{"PUT", "PATCH"},
    		AllowHeaders:     []string{"Origin"},
    		ExposeHeaders:    []string{"Content-Length"},
    		AllowCredentials: true,

    func Allow

    func Allow(opts *Options) beego.FilterFunc

      type Options

      type Options struct {
      	// If set, all origins are allowed.
      	AllowAllOrigins bool
      	// A list of allowed origins. Wild cards and FQDNs are supported.
      	AllowOrigins []string
      	// If set, allows to share auth credentials such as cookies.
      	AllowCredentials bool
      	// A list of allowed HTTP methods.
      	AllowMethods []string
      	// A list of allowed HTTP headers.
      	AllowHeaders []string
      	// A list of exposed HTTP headers.
      	ExposeHeaders []string
      	// Max age of the CORS headers.
      	MaxAge time.Duration

        Options represents Access Control options.

        func (*Options) Header

        func (o *Options) Header(origin string) (headers map[string]string)

          Header converts options into CORS headers.

          func (*Options) IsOriginAllowed

          func (o *Options) IsOriginAllowed(origin string) (allowed bool)

            IsOriginAllowed looks up if the origin matches one of the patterns generated from Options.AllowOrigins patterns.

            func (*Options) PreflightHeader

            func (o *Options) PreflightHeader(origin, rMethod, rHeaders string) (headers map[string]string)

              PreflightHeader converts options into CORS headers for a preflight response.
