use Plack::Builder;
use Plack::Builder::Conditionals;
# exports "match_if, addr, path, method, header, browser, any, all"
builder {
enable match_if addr(['192.168.0.0/24','127.0.0.1']),
"Plack::Middleware::ReverseProxy";
enable match_if all( path(qr!^/private!), addr( '!', [qw!127.0.0.1 ::1!] ) ),
"Plack::Middleware::Auth::Basic", authenticator => \&authen_cb;
enable match_if sub { my $env = shift; $env->{HTTP_X_ENABLE_FRAMEWORK} },
"Plack::Middleware::XFramework", framework => 'Test';
$app;
};
use Plack::Builder::Conditionals -prefx => 'c';
# exports "c_match_if, c_addr, c_path, c_method, c_header, c_any, c_all"
# DESCRIPTION
Plack::Builder::Conditionals is..
# FUNCTIONS
- match\_if
enable match_if addr('127.0.0.1'), "Plack::Middleware::ReverseProxy";
enable match_if sub { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' }, "Plack::Middleware::ReverseProxy";
As like Plack::Builder's enable\_if enable middleware if given conditions return true
- addr
addr('127.0.0.1');
addr([qw!192.168.0.0/24 127.0.0.1 ::1!]);
addr('!','127.0.0.1');
return true if REMOTE\_ADDR is found in the CIDR range. If first argument is '!', return the opposite result.
This function supports IPv6 addresses
- path
path('/')
path(qr!^/(\w+)/!)
path('!', qr!^/private!)
matching PATH\_INFO
- method
method('GET')
method(qr/^(get|head)$/i)
method(qw(GET HEAD))
method('!','GET')
method('!', qr/^(post|put)$/i)
method('!', qw(POST PUT))
- header
header('User-Agent',qr/iphone/)
header('If-Modified-Since') #exists check
header('!', 'User-Agent',qr/MSIE/)
- browser
browser(qr/\bMSIE (7|8)/)
browser('!',qr!^Mozilla/4!);
Shortcut for header('User-Agent')
- all
all( method('GET'), path(qr!^/static!) )
return true if all conditions are return true
- any
any( path(qr!^/static!), path('/favicon.ico') )
return true if any condition return true
