Start the microservice using the command:
dart ./bin/run.dart

Use #
The easiest way to work with the microservice is to use client SDK.
The complete list of available client SDKs for different languages is listed in the Quick Links
If you use dart, then get references to the required libraries:

Pip.Services3.Commons : https://github.com/pip-services3-dart/pip-services3-commons-dart
Pip.Services3.Rpc:
https://github.com/pip-services3-dart/pip-services3-rpc-dart

Add pip-services3-commons-dart, pip-services3-rpc-dart and pip-services_accounts packages
import 'package:pip_services3_commons/pip_services3_commons.dart';
import 'package:pip_services3_rpc/pip_services3_rpc.dart';

import 'package:pip_services_accounts/pip_services_accounts.dart';

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
);
copied to clipboard
Instantiate the client and open connection to the microservice
// Create the client instance
var client = AccountsHttpClientV1(config);

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

// Connect to the microservice
try{
await client.open(null)
}catch() {
// Error handling...
}
// Work with the microservice
// ...
copied to clipboard
Now the client is ready to perform operations
// Create a new account
final ACCOUNT = AccountV1(
id: '1',
login: '[email protected]',
name: 'Test User 1',
deleted: false
);

// Create the account
try {
var account = await client.createAccount('123', ACCOUNT);
// Do something with the returned account...
} catch(err) {
// Error handling...
}
copied to clipboard
// Get the account
try {
var account = await client.getAccountByLogin(
null,
'[email protected]');
// Do something with account...

} catch(err) { // Error handling}
