se.rupy.http.Root

public class Root
extends Service

Secure Unique Identity Cluster. This solution is "wasteful"; but with 16-digit Base-58 keys and long ids, collisions should be rare, at least over the network.

Method Detail

getIp

public static java.lang.String[] getIp()

getHost

public static java.lang.String[] getHost()

create

public void create(Daemon daemon)
            throws java.lang.Exception

Description copied from class: Service

Initiate service dependencies. This is called when you hot-deploy the application / start the server. Important: This will be called for every chain instance of the service. So if you have multiple paths this will be called once for every path. Use static lock if you use this to start some singleton thread.

Overrides:

create in class Service

Parameters:

daemon - so you can setup yourself as a listener.

Throws:

java.lang.Exception

host

public static java.lang.String host()
                             throws java.lang.Exception

Throws:

java.lang.Exception

home

public static java.lang.String home()
                             throws java.lang.Exception

A cross functional Root home folder detection for your deploy. Usage example from logging in a user:

        public static class Login extends Service {
                public String path() { return "/login"; }
                public void filter(Event event) throws Event, Exception {
                        event.query().parse();

                        String mail = event.string("mail");
                        String pass = event.string("pass");

                        if(mail.length() > 0 && pass.length() > 0) {
                                File file = new File(Root.home() + "/node/user/mail" + Root.path(mail));

                                if(!file.exists()) {
                                        System.out.println(file);
                                        error(event, "Användare ej funnen.");
                                }

                                JSONObject user = new JSONObject(Root.file(file));

                                if(Deploy.hash(pass, "SHA").equals(user.getString("pass"))) {
                                        event.session().put("user", user);
                                }
                                else {
                                        error(event, "Fel lösenord.");
                                }
                        }

                        event.reply().header("Location", "user");
                        event.reply().code("302 Found");
                }
        }

Throws:

java.lang.Exception

local

public static java.lang.String local()

path

public java.lang.String path()

Description copied from class: Service

The identifier that should trigger this service. Or return null if you want to filter all 404 queries. For example "/admin". You can specify a service that should filter multiple identifiers by separating them with a ':' character. For example: if you want to identify a user before multiple services, return "/update:/query" here and set the index to 0 on the identity service and set index to 1 on the update and query filters. Then you use the following code to redirect to the login page for example:

 event.daemon().chain(event, "/login").filter(event);
 throw event; // stop the chain

or

 event.reply().header("Location", "/login");
 event.reply().code("302 Found");
 throw event; // stop the chain
 

Specified by:

path in class Service

Returns:

the path (URI) to the service(s).

filter

public void filter(Event event)
            throws Event,
                   java.lang.Exception

Description copied from class: Service

The service method, equivalent of HttpServlet.service().

Specified by:

filter in class Service

Throws:

Event - if you want to break the filter chain

java.lang.Exception

sync

public static JSONObject sync(Event event,
              java.lang.String type,
              java.lang.String sort,
              boolean create)
                       throws java.lang.Exception

Create and synchronize a unique node key across the cluster. The id is generated by hashing the key with hash(String).

Throws:

java.lang.Exception

id

public static long id(java.lang.String key,
      java.lang.String type)
               throws java.lang.Exception
