NAME ^

Apache2::URI - Perl API for manipulating URIs

Synopsis ^

  use Apache2::URI ();
  
  $hostport = $r->construct_server();
  $hostport = $r->construct_server($hostname);
  $hostport = $r->construct_server($hostname, $port);
  $hostport = $r->construct_server($hostname, $port, $pool);
  
  $url = $r->construct_url();
  $url = $r->construct_url($rel_uri);
  $url = $r->construct_url($rel_uri, $pool);
  
  $parsed_uri = $r->parse_uri($uri);
  
  $parsed_uri = $r->parsed_uri();
  
  $url = join '%20', qw(one two three);
  Apache2::URI::unescape_url($url);

Description ^

While APR::URI provides a generic API to dissect, adjust and put together any given URI string, Apache2::URI provides an API specific to Apache, by taking the information directly from the $r object. Therefore when manipulating the URI of the current HTTP request usually methods from both classes are used.

API ^

Apache2::URI provides the following functions and methods:

construct_server

Construct a string made of hostname and port

  $hostport = $r->construct_server();
  $hostport = $r->construct_server($hostname);
  $hostport = $r->construct_server($hostname, $port);
  $hostport = $r->construct_server($hostname, $port, $pool);
obj: $r ( Apache2::RequestRec object )

The current request object

opt arg1: $hostname ( string )

The hostname of the server.

If that argument is not passed, $r->get_server_name is used.

opt arg2: $port ( string )

The port the server is running on.

If that argument is not passed, $r->get_server_port is used.

opt arg3: $pool ( APR::Pool object )

The pool to allocate the string from.

If that argument is not passed, $r->pool is used.

ret: $hostport ( string )

The server's hostport string

since: 2.0.00

Examples:

construct_url

Build a fully qualified URL from the uri and information in the request rec:

  $url = $r->construct_url();
  $url = $r->construct_url($rel_uri);
  $url = $r->construct_url($rel_uri, $pool);
obj: $r ( Apache2::RequestRec object )

The current request object

opt arg1: $rel_uri ( string )

The path to the requested file (it may include a concatenation of path, query and fragment components).

If that argument is not passed, $r->uri is used.

opt arg2: $pool ( APR::Pool object )

The pool to allocate the URL from

If that argument is not passed, $r->pool is used.

ret: $url ( string )

A fully qualified URL

since: 2.0.00

Examples:

parse_uri

Break apart URI (affecting the current request's uri components)

  $r->parse_uri($uri);
obj: $r ( Apache2::RequestRec object )

The current request object

arg1: $uri ( string )

The uri to break apart

ret: no return value
warning:

This method has several side-effects explained below

since: 2.0.00

This method call has the following side-effects:

  1. sets $r->args to the rest after '?' if such exists in the passed $uri, otherwise sets it to undef.
  2. sets $r->uri to the passed $uri without the $r->args part.
  3. sets $r->hostname (if not set already) using the (scheme://host:port) parts of the passed $uri.

parsed_uri

Get the current request's parsed uri object

  my $uri = $r->parsed_uri();
obj: $r ( Apache2::RequestRec object )

The current request object

ret: $uri ( APR::URI object )

The parsed uri

since: 2.0.00

This object is suitable for using with APR::URI::rpath

unescape_url

Unescape URLs

  Apache2::URI::unescape_url($url);
obj: $url ( string )

The URL to unescape

ret: no return value

The argument $url is now unescaped

since: 2.0.00

Example:

  my $url = join '%20', qw(one two three);
  Apache2::URI::unescape_url($url);

$url now contains the string:

  "one two three";
