Sessions Microservice Client SDK for Dart

This is a Dart client SDK for pip-services-sessions microservice.

Download

Right now the only way to get the microservice is to check it out directly from github repository

git clone git@github.com:pip-services-users/pip-clients-sessions-dart.git

Pip.Service team is working to implement packaging and make stable releases available for your as zip downloadable archieves.

Contract

Logical contract of the microservice is presented below. For physical implementation (HTTP/REST), please, refer to documentation of the specific protocol.

class SessionV1 implements IStringIdentifiable {
  /* Identification */
  String id;
  String user_id;
  String user_name;

  /* Session info */
  bool active;
  DateTime open_time;
  DateTime close_time;
  DateTime request_time;
  String address;
  String client;

  /* Cached content */
  var user;
  var data;
}

abstract class ISessionsV1 {
  Future<DataPage<SessionV1>> getSessions(
      String correlationId, FilterParams filter, PagingParams paging);

  Future<SessionV1> getSessionById(String correlationId, String id);

  Future<SessionV1> openSession(
      String correlationId,
      String user_id,
      String user_name,
      String address,
      String client,
      dynamic user,
      dynamic data);

  Future<SessionV1> storeSessionData(String correlationId, String sessionId, dynamic data);

  Future<SessionV1> updateSessionUser(String correlationId, String sessionId, dynamic user);

  Future<SessionV1> closeSession(String correlationId, String sessionId);

  Future<SessionV1> deleteSessionById(String correlationId, String sessionId);
}

Use

The easiest way to work with the microservice is to use client SDK.

Define client configuration parameters that match the configuration of the microservice's external API

// Client configuration
var httpConfig = ConfigParams.fromTuples(
	"connection.protocol", "http",
	"connection.host", "localhost",
	"connection.port", 8080
);

Instantiate the client and open connection to the microservice

// Create the client instance
var client = SessionsHttpClientV1(config);

// Configure the client
client.configure(httpConfig);

// Connect to the microservice
try{
  await client.open(null)
}catch() {
  // Error handling...
}       
// Work with the microservice
// ...

Now the client is ready to perform operations

    // Open new session
    try {
      var session1 = await client.openSession('123', '1', 'User 1', 'localhost', 'test', 'abc');
      // Do something with the returned session...
    } catch(err) {
      // Error handling...     
    }

// Get the session
try {
var session = await client.getSessionById(
    null,
    session1.id);
    // Do something with session...

    } catch(err) { // Error handling}
