NAME

HTTP::MobileAgent - HTTP mobile user agent string parser

SYNOPSIS

use HTTP::MobileAgent;

my $agent = HTTP::MobileAgent->new(Apache->request);
# or $agent = HTTP::MobileAgent->new; to get from %ENV
# or $agent = HTTP::MobileAgent->new($agent_string);

if ($agent->is_docomo) {
    # or if ($agent->name eq 'DoCoMo')
    # or if ($agent->isa('HTTP::MobileAgent::DoCoMo'))
    # it's NTT DoCoMo i-mode.
    # see what's available in H::MA::DoCoMo
} elsif ($agent->is_j_phone) {
    # it's J-Phone.
    # see what's available in H::MA::JPhone
} elsif ($agent->is_ezweb) {
    # it's KDDI/EZWeb.
    # see what's available in H::MA::EZweb
} else {
    # may be PC
    # $agent is H::MA::NonMobile
}

my $display = $agent->display;	# HTTP::MobileAgent::Display
if ($display->color) { ... }

DESCRIPTION

HTTP::MobileAgent parses HTTP_USER_AGENT strings of (mainly Japanese) mobile HTTP user agents. It'll be useful in page dispatching by user agents.

METHODS

Here are common methods of HTTP::MobileAgent subclasses. More agent specific methods are described in each subclasses. Note that some of common methods are also overrided in some subclasses.

new

$agent = HTTP::MobileAgent->new;
$agent = HTTP::MobileAgent->new($r);	# Apache or HTTP::Request
$agent = HTTP::MobileAgent->new($ua_string);

parses HTTP headers and constructs HTTP::MobileAgent subclass instance. If no argument is supplied, $ENV{HTTP_*} is used.

Note that you nees to pass Aapche or HTTP::Requet object to new(), as some mobile agents put useful information on HTTP headers other than only User-Agent: (like x-jphone-msname in J-Phone).

user_agent

print "User-Agent: ", $agent->user_agent;

returns User-Agent string.

name

print "name: ", $agent->name;

returns User-Agent name like 'DoCoMo'.

is_docomo, is_j_phone, is_ezweb, is_wap1, is_wap2, is_non_mobile

if ($agent->is_docomo) { }

returns if the agent is DoCoMo, J-Phone or EZweb.

display

my $display = $agent->display;

returns HTTP::MobileAgent::Display object. See HTTP::MobileAgent::Display for details.

WARNINGS

Following warnings might be raised when $^W is on.

"%s: no match. Might be new variants. please contact the author of HTTP::MobileAgent!"

User-Agent: string does not match patterns provided in subclasses. It may be faked user-agent or a new variant. Feel free to mail me to inform this.

NOTE

"Why not adding this module as an extension of HTTP::BrowserDetect?"

Yep, I tried to do. But the module's code seems hard enough for me to extend and don't want to bother the author for this mobile-specific features. So I made this module as a separated one.

MORE IMPLEMENTATIONS

If you have any idea / request for this module to add new subclass, I'm open to the discussion or (more preferable) patches. Feel free to mail me.

OTHER LANGUAGE BINDINGS

This module is now ported to PHP as Net::UserAgent::Mobile by Atsuhiro KUBO. See http://pear.php.net/package-info.php?pacid=180 for details.
