NAME
Apache2::URI - Perl API for manipulating URIs
Synopsis
use Apache2::URI ();

$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:
o Assuming that:
$r->get_server_name == "localhost";
$r->get_server_port == 8001;
The code:
$hostport = $r->construct_server();
returns a string:
localhost:8001
o 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" )
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:
o 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.
o 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
"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";
