Types

type Config

type Config struct {
	// Specifies either the origins, which tells browsers to allow that origin
	// to access the resource; or else — for requests without credentials —
	// the "*" wildcard, to tell browsers to allow any origin to access the resource.
	AllowedOrigins []string

	// Specifies the method or methods allowed when accessing the resource.
	// This is used in response to a preflight request.
	// The conditions under which a request is preflighted are discussed above.
	AllowedMethods []string

	// This is used in response to a preflight request to indicate which HTTP headers
	// can be used when making the actual request.
	AllowedHeaders []string

	// 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.
	// Note that simple GET requests are not preflighted, and so if a request is made
	// for a resource with credentials, if this header is not returned with the resource,
	// the response is ignored by the browser and not returned to web content.
	AllowCredentials bool

	// Indicates how long, in seconds, the results of a preflight request can be cached
	AllowMaxAge int

	// Header or headers to lets a server whitelist headers that browsers are allowed to access.
	ExposedHeaders []string
