CGI::Easy::Util - low-level helpers for HTTP/CGI


This document describes CGI::Easy::Util version v2.0.1


    use CGI::Easy::Util qw( date_http date_cookie make_cookie );

    my $mtime = (stat '/some/file')[9];
    printf "Last-Modified: %s\r\n", date_http($mtime);

    printf "Set-Cookie: a=5; expires=%s\r\n", date_cookie(time+86400);

    printf make_cookie({ name=>'a', value=>5, expires=>time+86400 });

    use CGI::Easy::Util qw( uri_unescape_plus
                            burst_urlencoded burst_multipart );

    my $s = uri_unescape_plus('a+b%20c');   # $s is 'a b c'

    my %param = %{ burst_urlencoded($ENV{QUERY_STRING}) };
    my $a = $param{a}[0];

    ($params, $filenames, $mimetypes) = burst_multipart($STDIN_data, $1)

    my $avatar_mimetype = $mimetypes->{avatar}[0];


This module contain low-level function which you usually doesn't need - use CGI::Easy::Request and CGI::Easy::Headers instead.


Nothing by default, but all documented functions can be explicitly imported.



    $date = date_http( $seconds );

Convert given time into text format suitable for sending in HTTP headers.

Return date string.

    $date = date_cookie( $seconds );

Convert given time into text format suitable for sending in HTTP header Set-Cookie's "expires" option.

Return date string.

    $header = make_cookie( \%cookie );

Convert HASHREF with cookie properties to "Set-Cookie: ..." HTTP header.

Possible keys in %cookie:

    name        REQUIRED STRING
    value       OPTIONAL STRING (default "")
    domain      OPTIONAL STRING (default "")
    path        OPTIONAL STRING (default "/")
    expires     OPTIONAL STRING or SECONDS
    secure      OPTIONAL BOOL

Format for "expires" should be either correct date 'Thu, 01-Jan-1970 00:00:00 GMT' or time in seconds.

Return HTTP header string.


    $unescaped = uri_unescape_plus( $uri_escaped_value );

Same as uri_unescape from URI::Escape but additionally replace '+' with space.

Return unescaped string.


    my %param = %{ burst_urlencoded( $url_encoded_name_value_pairs ) };

Unpack name/value pairs from url-encoded string (like $ENV{QUERY_STRING} or STDIN content for non-multipart forms sent using POST method).

Return HASHREF with params, each param's value will be ARRAYREF (because there can be more than one value for any parameter in source string).


    ($params, $filenames, $mimetypes) = burst_multipart( $buffer, $boundary );

Unpack buffer with name/value pairs in multipart/form-data format. This format usually used to upload files from forms, and each name/value pair may additionally contain 'file name' and 'mime type' properties.

Return three HASHREF (with param's values, with param's file names, and with param's mime types), all values in all three HASHREF are ARRAYREF (because there can be more than one value for any parameter in source string). For non-file-upload parameters corresponding values in last two hashes (with file names and mime types) will be undef().
