API

Errors

Whenever pitaya admin responds with an error, it will be in the following format:

{"success":false, "message":[msg], "reason": [error]}

Client Request

Establishes a websocket connection with pitaya admin that can be used to send requests to handlers and receive theirs outputs through a pitaya client connected to given server address.

• URL

  /request

• Method

  GET

• URL Params

  Required:

  address=[pitaya server address]

  You also need to add origins to request.whitelist configuration. When upgrading the connection, pitaya admin will only accept requests incoming from hosts specified in the whitelist.

• Data Params

  After the websocket connection is set, pitaya admin will listen to requests in the following structure:

      Route       Pitaya route to handler
      Payload     The data that will be sent to the handler
      IsRequest   Whether this should be sent as a request or a notify
  

• Response Example

  After the websocket connection is set and the pitaya client connects to the given server address, any message sent to the client will be forwarded as a response. It will return an error if it fails to establish any of the connections.

Documentation

Returns server auto documentation given its type. Target server must implement pitaya's auto documentation remote. The documentation remote is usefull on servers that have many handlers and remotes.

• URL

  /docs

• Method

  GET

• URL Params

  Required:

  type=[server type]

  Optional:

  methodtype=[either "remote" or "handler"]

  Specifies whether to get documentation only for remote's or handler's methods.

  route=[pitaya route]

  Specifies a single method route to get its documentation. Must have specified methodtype as well.

  getProtos=["1"]

  Specifies if the documentation will have protobuf message names when set to 1.

• Response Example

  Auto documentation as implemented in remote or an error.

• Requirements

  As stated above, in order for documentation routes to work, you will need to implement on the server a remote for pitaya's auto documentation. If you want to be able to retrieve the documentation for a server type, lets say connector, you have to create the following remote on the connector.

func (c *ConnectorRemote) Docs(ctx context.Context, flag *protos.DocMsg) (*protos.Doc, error) {
    d, err := pitaya.Documentation(flag.GetGetProtos())

    if err != nil {
        return nil, err
    }
    doc, err := json.Marshal(d)

    if err != nil {
        return nil, err
    }

    return &protos.Doc{Doc: string(doc)}, nil
}

The boolean inside flag passed to pitaya.Documentation specifies if the documentation will have protobuf message names. Note that in order to pitaya admin RPC to work, documentation must have protos name.

Kick Users

Send a kick packet to users in a given user list, breaking the users connections to the pitaya server

• URL

  /user/kick

• Method

  POST

• Data Params

  A kick message struct:

      Uids          Array with users IDs
      FrontendType  The type of the frontend server the users are connected to
  

• Response Example

  {"success" : true}

  If the user were kicked or an error otherwise

List Servers

Returns a json array with servers information

• URL

  /servers

• Method

  GET

• URL Params

  Optional:

  type=[server type]

  If no server type is given, all servers are returned

• Response Example

  {"success" : true, "response":[{"id":"740bcdba-1a9b-4790-9f07-ddf9f33a912e","type":"admin","metadata":{},"frontend":false}]}

RPC

Sends a RPC to a pitaya server. Target server must implement remotes for protobuf descriptors and auto documentation.

• URL

  /rpc

• Method

  POST

• Data Params

  A RPC message struct:

      Route          Remote's route
      FrontendType   Remote's type
      ServerID       Remote's server ID (can be empty)
      Meta           Remote's args data serialized
  

  Since pitaya's RPC methods take protos as an argument and return protos as a response, pitaya admin uses reflection alongside with pitaya's autodoc feature to build dynamic messages and send them to the server.

• Response Example

  {"success" : true, "response":{"Msg":"hi im a rpc msg"}}

  If the RPC was sent successfully, response will contain the response returned by the method, otherwise, it will be an error.

• Requirements

  As stated, in order to RPC work properly, you will need a remote that provides protobuf descriptors via reflection and the documentation's remote, both functions are available on pitaya, you only need to expose them on a remote on the servers that you want to be able to send RPC via pitaya admin. This allows pitaya-admin to work with RPCs without any proto specification at compile time. An remote example for, lets say, send RPC to servers of type connector is presented below

func (c *ConnectorRemote) Docs(ctx context.Context, flag *protos.DocMsg) (*protos.Doc, error) {
    d, err := pitaya.Documentation(flag.GetGetProtos())

    if err != nil {
        return nil, err
    }

    doc, err := json.Marshal(d)

    if err != nil {
        return nil, err
    }

    return &protos.Doc{Doc: string(doc)}, nil
}

func (c *ConnectorRemote) Proto(ctx context.Context, message *protos.ProtoName) (*protos.ProtoDescriptor, error) {
    protoDescriptor, err := pitaya.Descriptor(message.GetName())

    if err != nil {
        return nil, err
    }

    return &protos.ProtoDescriptor{
        Desc: protoDescriptor,
    }, nil
}

All of the used protobuf messages can be found at pitaya-protos. You can implement the remotes on your own components as shown above, or you can use the components defined at the package remotes.

Send Push

Sends a push notification to users in a given user list

• URL

  /user/push

• Method

  POST

• Data Params

  A push message struct:

      Uids          Array with users IDs
      Route         Route to push
      Message       Notification message
      FrontendType  The type of the frontend server the users are connected to
  

• Response Example

  {"success" : true}

  If the message was sent or an error otherwise.

Configuring Pitaya Admin

In order for Pitaya Admin to work, the following configuration must be set using environment variables or passing it through a .yaml configuration file.

Example yaml config:

routes:
  protos: "protoRemote.proto"
  docs: "docRemote.docs"
request:
  whitelist:
    - localhost:8080
  readdeadline: 5m

• routes.protos is the protobuf descriptor remote route without server type.
• routes.docs is the documentation remote route without server type.
• request.readdeadline is the websocket connection deadline
• request.whitelist is the accepted origins slice for the websocket connection

If environment variables are used, their prefix must be PITAYAADMIN. It is important to note that you also have to setup Pitaya configuration such as etcd configs according to your needs.
