Overview ▾

Package mime implements parts of the MIME spec.

func AddExtensionType

func AddExtensionType(ext, typ string) error

AddExtensionType sets the MIME type associated with the extension ext to typ. The extension should begin with a leading dot, as in ".html".

func FormatMediaType

func FormatMediaType(t string, param map[string]string) string

FormatMediaType serializes mediatype t and the parameters param as a media type conforming to RFC 2045 and RFC 2616. The type and parameter names are written in lower-case. When any of the arguments result in a standard violation then FormatMediaType returns the empty string.

func ParseMediaType

func ParseMediaType(v string) (mediatype string, params map[string]string, err error)

ParseMediaType parses a media type value and any optional parameters, per RFC 1521. Media types are the values in Content-Type and Content-Disposition headers (RFC 2183). On success, ParseMediaType returns the media type converted to lowercase and trimmed of white space and a non-nil map. The returned map, params, maps from the lowercase attribute to the attribute value with its case preserved.

func TypeByExtension

func TypeByExtension(ext string) string

TypeByExtension returns the MIME type associated with the file extension ext. The extension ext should begin with a leading dot, as in ".html". When ext has no associated type, TypeByExtension returns "".

The built-in table is small but on unix it is augmented by the local system's mime.types file(s) if available under one or more of these names:

/etc/mime.types
/etc/apache2/mime.types
/etc/apache/mime.types

Windows system mime types are extracted from registry.

Text types have the charset parameter set to "utf-8" by default.
