Information of a few universal deployment eventualities are within the Dancer::Deployment handbook web page, which comes as a part of the normal Dancer distribution. simply input perldoc Dancer::Deployment on the command line. For extra information of PSGI (and Plack, a reference implementation of the specification), see the project’s site at http://plackperl. org. including safety most likely, you’d wish to reveal your interpreting record to an individual who’s , yet you’d like it if purely you could replace it. For that we have to introduce a few defense. We’re going use a few rather easy authentication, yet i am hoping it will likely be noticeable the best way to expand it to be used within the genuine global. We’re going so as to add the concept that of a logged in person. And we’re going to shop no matter if the present consumer is logged in or logged out utilizing a consultation cookie. help for periods comes as part of the traditional Dancer distribution, yet in an effort to shop your consultation in a cookie, it is important to set up the additional Dancer::Session::Cookie module from CPAN. Having put in the module, you want to configure it by means of including the next traces on your config. yml dossier: consultation: cookie session_cookie_key: somerandomnonsense the price of the cookie key should be any random string – the extra random the higher. Mine isn’t a very good instance. with a purpose to upload consultation aid, we have to upload use Dancer::Session to the checklist of modules close to the pinnacle of BookWeb. pm. BookWeb. pm Now we have to take into consideration how our safety will paintings. I’m going to outline an inventory of paths which are public. someone can see these pages, yet somebody attempting to entry pages outdoors of this record may be triggered to log in in the event that they haven’t already. Dancer has the idea that of a prior to hook that is fired earlier than any direction is administered. That’s an ideal position to envision even if the consumer is authorized to do no matter what they are attempting to do: my %public_path = map { $_ => 1 } (‘/’, ‘/login’, ‘/search’); hook earlier than => sub { www. linuxformat. com 1/16/12 12:43:47 PM Modern Perl if (! session(‘logged_in’) and ! $public_path{request->path_info}) { var requested_path => request->path_info; request->path_info(‘/login’); } }; the 1st line of this code defines a hash referred to as %public_ course. The keys of the hash are the general public paths and the linked values are all 1. This makes it effortless to ascertain no matter if a course is public or now not. the remainder of the code snippet defines the sooner than hook. We fee the consultation to determine if the consumer is logged in and, in the event that they aren’t, whether or not they are allowed to work out the web page that they're attempting to stopover at. the trail they've got asked is given via the present request’s path_info procedure. We shop that unique course in a short lived scratch variable known as requested_path and overwrite the asked course with a request to the login web page, which we now have to write. Logging in is dealt with with routes, like this: get ‘/login’ => sub { template ‘login’, { direction => vars->{requested_path } }; }; submit ‘/login’ => sub { if (params->{user} eq ‘reader’ && params->{pass} eq ‘letmein’) { consultation ‘logged_in’ => 1; } redirect params->{path} || ‘/’; }; it is a great representation of the ability of Dancer routes.
