Applications microservice for Pip.Services in Dart. It keeps a list of supported applications that are referenced from other content microservices.
Examples for Applications Microservice #
This is applications microservice from Pip.Services library. It keeps a list of supported applications that are referenced from other content microservices.
Define configuration parameters that match the configuration of the microservice's external API
// Service/Client configuration
var httpConfig = ConfigParams.fromTuples(
"connection.protocol", "http",
"connection.host", "localhost",
"connection.port", 8080
);
Instantiate the service
persistence = ApplicationsMemoryPersistence();
persistence.configure(ConfigParams());
controller = ApplicationsController();
controller.configure(ConfigParams());
service = ApplicationsHttpServiceV1();
service.configure(httpConfig);
var references = References.fromTuples([
Descriptor('pip-services-applications', 'persistence', 'memory',
'default', '1.0'),
persistence,
Descriptor('pip-services-applications', 'controller', 'default',
'default', '1.0'),
controller,
Descriptor(
'pip-services-applications', 'service', 'http', 'default', '1.0'),
service
]);
controller.setReferences(references);
service.setReferences(references);
await persistence.open(null);
await service.open(null);
Instantiate the client and open connection to the microservice
// Create the client instance
var client = ApplicationsHttpClientV1(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
// Create a new application
final APPLICATION = ApplicationV1.fromMap({
id: 'my_app',
name: 'My Application',
product: 'My Samples'
});
// Create the application
try {
var application = await client.createApplication('123', APPLICATION);
// Do something with the returned application...
} catch(err) {
// Error handling...
}
// Get the list of applications for 'My Samples' product
try {
var page = await client.getApplications(
null,
{
product: 'My Samples'
},
{
total: true,
skip: 0,
take: 10
});
// Do something with page...
} catch(err) { // Error handling}
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.
