Examples for Message Distribution Microservice #

This microservice is distributes messages to one or many recipients using their configured delivery methods: email or sms.

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 = MessageDistributionHttpClientV1(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

// Send message to users
var recipient1 = RecipientV1(id: '1', email: 'user1@somewhere.com', phone: '+1234567890');
var recipient2 = RecipientV1(id: '2', email: 'user2@somewhere.com', phone: '+0987654321');
var message = MessageV1(subject: 'Test', 
                             text: 'This is a test message. Please, ignore it');
await client.sendMessages(
    null,
    [
        recipient1,
        recipient2
    ],
    message,
    null,
    DeliveryMethod.All
);

In the help for each class there is a general example of its use. Also one of the quality sources are the source code for the tests.
