NAME¶
HTTP::Config - Configuration for request and response objects
SYNOPSIS¶
use HTTP::Config; my $c = HTTP::Config->new; $c->add(m_domain => ".example.com", m_scheme => "http", verbose => 1); use HTTP::Request; my $request = HTTP::Request->new(GET => "http://www.example.com"); if (my @m = $c->matching($request)) { print "Yadayada\n" if $m[0]->{verbose}; }
DESCRIPTION¶
An "HTTP::Config" object is a list of entries that can be matched against request or request/response pairs. Its purpose is to hold configuration data that can be looked up given a request or response object.
Each configuration entry is a hash. Some keys specify matching to occur against attributes of request/response objects. Other keys can be used to hold user data.
The following methods are provided:
- $conf = HTTP::Config->new
- Constructs a new empty "HTTP::Config" object and returns it.
- $conf->entries
- Returns the list of entries in the configuration object. In scalar context returns the number of entries.
- $conf->empty
- Return true if there are no entries in the configuration object. This is just a shorthand for "not $conf->entries".
- $conf->add( %matchspec, %other )
- $conf->add( \%entry )
- Adds a new entry to the configuration. You can either pass separate key/value pairs or a hash reference.
- $conf->remove( %spec )
- Removes (and returns) the entries that have matches for all the key/value pairs in %spec. If %spec is empty this will match all entries; so it will empty the configuation object.
- $conf->matching( $uri, $request, $response )
- $conf->matching( $uri )
- $conf->matching( $request )
- $conf->matching( $response )
- Returns the entries that match the given $uri,
$request and $response
triplet.
If called with a single $request object then the $uri is obtained by calling its 'uri_canonical' method. If called with a single $response object, then the request object is obtained by calling its 'request' method; and then the $uri is obtained as if a single $request was provided.
The entries are returned with the most specific matches first. In scalar context returns the most specific match or "undef" in none match.
- $conf->add_item( $item, %matchspec )
- $conf->remove_items( %spec )
- $conf->matching_items( $uri, $request, $response )
- Wrappers that hides the entries themselves.
Matching¶
The following keys on a configuration entry specify matching. For all of these you can provide an array of values instead of a single value. The entry matches if at least one of the values in the array matches.
Entries that require match against a response object attribute will never match unless a response object was provided.
- m_scheme => $scheme
- Matches if the URI uses the specified scheme; e.g. "http".
- m_secure => $bool
- If $bool is TRUE; matches if the URI uses a secure scheme. If $bool is FALSE; matches if the URI does not use a secure scheme. An example of a secure scheme is "https".
- m_host_port => "$hostname:$port"
- Matches if the URI's host_port method return the specified value.
- m_host => $hostname
- Matches if the URI's host method returns the specified value.
- m_port => $port
- Matches if the URI's port method returns the specified value.
- m_domain => ".$domain"
- Matches if the URI's host method return a value that within the given domain. The hostname "www.example.com" will for instance match the domain ".com".
- m_path => $path
- Matches if the URI's path method returns the specified value.
- m_path_prefix => $path
- Matches if the URI's path is the specified path or has the specified path as prefix.
- m_path_match => $Regexp
- Matches if the regular expression matches the URI's path. Eg. qr/\.html$/.
- m_method => $method
- Matches if the request method matches the specified value. Eg. "GET" or "POST".
- m_code => $digit
- m_code => $status_code
- Matches if the response status code matches. If a single digit is specified; matches for all response status codes beginning with that digit.
- m_proxy => $url
- Matches if the request is to be sent to the given Proxy server.
- m_media_type => "*/*"
- m_media_type => "text/*"
- m_media_type => "html"
- m_media_type => "xhtml"
- m_media_type => "text/html"
- Matches if the response media type matches.
With a value of "html" matches if $response->content_is_html returns TRUE. With a value of "xhtml" matches if $response->content_is_xhtml returns TRUE.
- m_uri__$method => undef
- Matches if the URI object provides the method.
- m_uri__$method => $string
- Matches if the URI's $method method returns the given value.
- m_header__$field => $string
- Matches if either the request or the response have a header $field with the given value.
- m_response_attr__$key => undef
- m_response_attr__$key => $string
- Matches if the response object has that key, or the entry has the given value.
