Where did you find this syntax for the request and what does it do? `get '/login:username:password' => sub {` [download] Maybe you wanted to just use `get '/login' => sub {` [download]	[reply] [d/l] [select]

I have found this usage on http://search.cpan.org/~sukria/Dancer2-0.01/lib/Dancer2/Manual.pod Under " NAMED MATCHING A route pattern can contain one or more tokens (a word prefixed with ':'). Each token found in a route pattern is used as a named-pattern match. Any match will be set in the params hashref."	[reply]

I think the documentation is misleading here. Only elements of the path can be matched this way, with `/` as delimiter. So you will need: `get '/login/:username/:password' => sub { ...` [download] But you should consider that such a `GET` request will need Javascript for logging in to the site, where a normal form submission will not need Javascript.

Here is what I was talking about, a peek behind the curtain, what it means to use :paramname #!/usr/bin/perl -- use strict; use warnings; sub ddd { use Data::Dumper; print Data::Dumper->new([@_])->Useqq(1)->D +ump, "\n"; } use Dancer2; get '/login:username:password' => sub { rand }; get '/signon/:username/:password' => sub { rand }; #~ ddd( app() ); ddd( app()->routes->{get} ); __END__ $VAR1 = [ bless( { "options" => {}, "_params" => [ "username:password" ], "spec_route" => "/login:username:password", "regexp" => "^\\/login(?#token)([^\\/]+)\$", "method" => "get", "_should_capture" => 1, "code" => sub { "DUMMY" }, "prefix" => undef }, 'Dancer2::Core::Route' ), bless( { "options" => {}, "_params" => [ "username", "password" ], "spec_route" => "/signon/:username/:password", "regexp" => "^\\/signon\\/(?#token)([^\\/]+)\\/(?#t +oken)([^\\/]+)\$", "method" => "get", "_should_capture" => 1, "code" => sub { "DUMMY" }, "prefix" => undef }, 'Dancer2::Core::Route' ) ]; [download] https://metacpan.org/pod/distribution/Dancer2/lib/Dancer2/Cookbook.pod#Authentication https://metacpan.org/pod/distribution/Dancer2/lib/Dancer2/Cookbook.pod#Password-Hashing https://metacpan.org/pod/Dancer2::Plugin::Passphrase#Usage Re: SessionID on a windows server (secure cookies)	[reply] [d/l]

When I try to access it from the webpage http://localhost:5000?username=foo&password=bar I am getting 404 error ? Hmm, how does that url relate to this one `get '/login:username:password'` ? If you remove the host there is only `?user...` ... which doesn't look like `/login....` See https://metacpan.org/pod/Dancer2::Manual#Declaring-Routes, URI	[reply] [d/l] [select]
