Security, Basic Authorization

You can enable authorization in zero system as following steps:

1. Configuration

In your configuration vertx.yml, you must define lime extend node as following:

zero:
  lime: secure

Then it means that you must create new up.god.file named vertx-secure.yml instead with following content:

secure:
  # Standard Type
  mongox:
    type: mongo
    config:
      collectionName: DB_USER
      saltStyle: NO_SALT

Zero system provide some standard authorization by type ( Now support mongo ).

2. Create new class

Then you can create new class as following:

import io.vertx.core.json.JsonObject;
import io.vertx.ext.auth.mongo.MongoAuth;
import io.vertx.ext.web.handler.AuthHandler;
import io.vertx.up.annotations.Authenticate;
import io.vertx.up.annotations.Wall;
import io.vertx.mod.plugin.mongo.MongoInfix;
import io.vertx.up.secure.component.BasicOstium;

@Wall(value = "mongox", path = "/exp4/*")
public class MongoKeeper {

    @Authenticate
    public AuthHandler authenticate(final JsonObject config) {
        return BasicOstium.create(
            MongoAuth.create(MongoInfix.getClient(), config)
        );
    }
}

This class is annotated with @Wall, if the path is not set, it will be the value /* for all routes, the value should be configured in vertx-secure.yml.in current example it’s mongox. You can define more than one walls for each routes. Then you must create the AuthHandler method to create the AuthHandler, now you can use BasicOstium to create basic authorization handler, also this method must be annotated with @Authenticate.

• The method must be annotated with @Authenticate to mean that this method will provide AuthHandler for authenticate.
• In this class, you must mot use any Inject Dependency to get instance such as MongoClient, because this @Wall will be processed in start up phase instead of request phase.
• We recommend to use BasicOstium instead of standard vert.x BasicAuthHandler because the class BasicOstium will bind to Resource Model instance Envelop to provide zero format http response.

3. Example response

Once you set the @Wall, you must send request with Authorization http header or your’ll get following response:

{
    "code": -60012,
    "message": "[ERR-60012] (BasicPhylum) Web Exception occus: (401) - (Security) Unauthorized request met in request."
}
