Apache2::URI - Perl API for manipulating URIs

  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);

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.

"Apache2::URI" provides the following functions and methods:

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);
The current request object
The hostname of the server.

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

The port the server is running on.

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

The pool to allocate the string from.

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

The server's hostport string

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
        

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);
The current request object
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.

The pool to allocate the URL from

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

A fully qualified URL

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
        

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

  $r->parse_uri($uri);
The current request object
The uri to break apart
This method has several side-effects explained below

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.

Get the current request's parsed uri object

  my $uri = $r->parsed_uri();
The current request object
The parsed uri
This object is suitable for using with "APR::URI::rpath"

Unescape URLs

  Apache2::URI::unescape_url($url);
The URL to unescape
The argument $url is now unescaped

Example:

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

$url now contains the string:

  "one two three";
