Mojolicious 基本登录

我正在 Mojolicious 中寻找身份验证。我有 2 个页面 momcorp1 和 momcorp2，但我不能 在页面之间，有人知道如何做到这一点。

我正在阅读有关“under”的内容，但我不知道如何做到这一点。

另一种形式是使用 -Mojolicious::Plugin::Authentication - 但更困难。

这是代码，当 1 单击链接到 momcorp 2 时，显示错误。

#!/usr/bin/env perl
use Mojolicious::Lite;

helper auth => sub {
my $self = shift;

return 1 if
$self->param('username') eq 'user1' and
$self->param('password') eq 'user1';
};

get '/login'=> sub { shift->render('login') };

under sub {
my $self = shift;
return 1 if $self->auth;

$self->render(text => 'denied');
return;
};

post 'momcorp' => sub { shift->render(template => 'momcorp1') };

post '/momcorp/carol' => sub { shift->render(template => 'momcorp2') 
};

app->start

这是您想要的示例

#!/usr/bin/env perl

  return 1 if
