Realms

Realms are rooted in /v1/realms collection.

Each realm defines a specific authentication provider. Any of the authentication providers can be used to obtain access tokens that can be used with Nexus.

Authorization notes

When modifying realms, the caller must have realms/write permissions on the path /.

When reading realms, the caller must have realms/read permissions on the path /.

Please visit Authentication & authorization section to learn more about it.

Create

This operation creates a realm.

PUT /v1/realms/{realm}

The following examples describe the payload used to create a realm.

Example

Request
sourcecurl -XPUT \
  -H "Content-Type: application/json" \
  "http://localhost:8080/v1/realms/realm1" \
  -d '{
        "name":"Nexus Dev",
        "openIdConfig":"http://localhost:8080/auth/realms/bbp-test/.well-known/openid-configuration",
        "logo":"http://localhost:8080/logo.png"
      }'
Payload
source{
  "name": "Nexus Dev",
  "openIdConfig": "http://localhost:8080/auth/realms/bbp-test/.well-known/openid-configuration",
  "logo": "http://localhost:8080/logo.png"
}
Response
source{

    "https://bluebrain.github.io/nexus/contexts/realms-metadata.json",
    "https://bluebrain.github.io/nexus/contexts/metadata.json"
  ],

Server Sent Events

This endpoint allows clients to receive automatic updates from the realms in a streaming fashion.

GET /v1/realms/events

where Last-Event-Id is an optional HTTP Header that identifies the last consumed realm event. It can be used for cases when a client does not want to retrieve the whole event stream, but to start after a specific event.

The response contains a series of realm events, represented in the following way

data:{payload}
event:{type}
id:{id}

where…

  • {payload}: Json - is the actual payload of the current realm
  • {type}: String - is a type identifier for the current realm. Possible types are: RealmCreated, RealmUpdated and RealmDeprecated
  • {id}: String - is the identifier of the realm event. It can be used in the Last-Event-Id HTTP Header
