Functions ¶

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 "".

Extensions are looked up first case-sensitively, then case-insensitively.

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

On Windows, MIME types are extracted from the registry.

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