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_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:
|
• |
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" )
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:
|
• |
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
"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";
