Guess media type for a file or a url
use LWP::MediaTypes qw(guess_media_type);
$type = guess_media_type("/tmp/foo.gif");
This module provides functions for handling media (also known as \s-1MIME\s0) types and encodings. The mapping from file extensions to media types is defined by the media.types file. If the ~/.media.types file exists it is used instead. For backwards compatibility we will also look for ~/.mime.types.
The following functions are exported by default: This function tries to guess media type and encoding for a file or a \s-1URI\s0. It returns the content type, which is a string like "text/html". In array context it also returns any content encodings applied (in the order used to encode the file). You can pass a \s-1URI\s0 object reference, instead of the file name. If the type can not be deduced from looking at the file name, then guess_media_type() will let the \*(C`-T\*(C' Perl operator take a look. If this works (and \*(C`-T\*(C' returns a \s-1TRUE\s0 value) then we return text/plain as the type, otherwise we return application/octet-stream as the type. The optional second argument should be a reference to a HTTP::Headers object or any object that implements the $obj->header method in a similar way. When it is present the values of the 'Content-Type' and 'Content-Encoding' will be set for this header. This function will return all suffixes that can be used to denote the specified media type(s). Wildcard types can be used. In a scalar context it will return the first suffix found. Examples: @suffixes = media_suffix('image/*', 'audio/basic'); $suffix = media_suffix('text/html');
The following functions are only exported by explicit request: Associate a list of file extensions with the given media type. Example: add_type("x-world/x-vrml" => qw(wrl vrml)); Associate a list of file extensions with an encoding type. Example: add_encoding("x-gzip" => "gz"); Parse media types files and add the type mappings found there. Example: read_media_types("conf/mime.types");
