Types

type Config

type Config struct {
	// Next defines a function to skip this middleware when returned true.
	//
	// Optional. Default: nil
	Next func(c *fiber.Ctx) bool

	// AllowOriginsFunc defines a function that will set the 'access-control-allow-origin'
	// response header to the 'origin' request header when returned true.
	//
	// Optional. Default: nil
	AllowOriginsFunc func(origin string) bool

	// AllowOrigin defines a list of origins that may access the resource.
	//
	// Optional. Default value "*"
	AllowOrigins string

	// AllowMethods defines a list methods allowed when accessing the resource.
	// This is used in response to a preflight request.
	//
	// Optional. Default value "GET,POST,HEAD,PUT,DELETE,PATCH"
	AllowMethods string

	// AllowHeaders defines a list of request headers that can be used when
	// making the actual request. This is in response to a preflight request.
	//
	// Optional. Default value "".
	AllowHeaders string

	// AllowCredentials indicates whether or not the response to the request
	// can be exposed when the credentials flag is true. When used as part of
	// a response to a preflight request, this indicates whether or not the
	// actual request can be made using credentials.
	//
	// Optional. Default value false.
	AllowCredentials bool

	// ExposeHeaders defines a whitelist headers that clients are allowed to
	// access.
	//
	// Optional. Default value "".
	ExposeHeaders string

	// MaxAge indicates how long (in seconds) the results of a preflight request
	// can be cached.
	// If you pass MaxAge 0, Access-Control-Max-Age header will not be added and
	// browser will use 5 seconds by default.
	// To disable caching completely, pass MaxAge value negative. It will set the Access-Control-Max-Age header 0.
	//
	// Optional. Default value 0.
	MaxAge int
}
