πŸ“¦ version 2.0.13, in nixos 26.05, nixpkgs unstable

πŸŽ€ NAME πŸŽ€

Bestie, this is Apache2::URI β€” the Perl API for manipulating URIs πŸ’…. The page itself is docs::a...he2::URI(3), from the User Contributed Perl Documentation, and it's here to make Apache URI wrangling make sense.

🌈 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);

πŸ’… Description πŸ’…

Okay so here's the vibe: while APR::URI gives you a generic API to dissect, adjust, and put together any given URI string, Apache2::URI gives you an API that's specific to Apache β€” it takes the information directly from the $r object. So when you're manipulating the URI of the current HTTP request, you usually use methods from both classes 🫢.

✨ API ✨

Apache2::URI provides the following functions and methods:

πŸ¦‹ "construct_server" πŸ¦‹

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) β€” the current request object.
  • opt arg1: $hostname (string) β€” the hostname of the server. If that argument is not passed, $r->get_server_name is used.
  • opt arg2: $port (string) β€” 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) β€” the pool to allocate the string from. If that argument is not passed, $r->pool is used.
  • ret: $hostport (string) β€” the server's hostport string.
  • since: 2.0.00

Examples:

  • Assuming that:
$r->get_server_name == "localhost";
$r->get_server_port == 8001;

The code:

$hostport = $r->construct_server();

returns a string:

localhost:8001
  • The following code sets the values explicitly:
$hostport = $r->construct_server("my.example.com", 8888);

and it returns a string:

my.example.com:8888

🌸 "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) β€” the current request object.
  • opt arg1: $rel_uri (string) β€” 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) β€” the pool to allocate the URL from. If that argument is not passed, $r->pool is used.
  • ret: $url (string) β€” a fully qualified URL.
  • since: 2.0.00

Examples:

  • Assuming that the request was:
http://localhost.localdomain:8529/test?args

The code:

my $url = $r->construct_url;

returns the string:

http://localhost.localdomain:8529/test

notice that the query (args) component is not in the string. You need to append it manually if it's needed.

  • Assuming that the request was:
http://localhost.localdomain:8529/test?args

The code:

my $rel_uri = "/foo/bar?tar";
my $url = $r->construct_url($rel_uri);

returns the string:

http://localhost.localdomain:8529/foo/bar?tar

πŸ”₯ "parse_uri" πŸ”₯

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

$r->parse_uri($uri);
  • obj: $r (Apache2::RequestRec object) β€” the current request object.
  • arg1: $uri (string) β€” 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.

πŸ‘‘ "parsed_uri" πŸ‘‘

Get the current request's parsed uri object:

my $uri = $r->parsed_uri();
  • obj: $r (Apache2::RequestRec object) β€” the current request object.
  • ret: $uri (APR::URI object) β€” 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) β€” the URL to unescape.
  • ret: no return value β€” 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";
