- A classic DDD with CQRS-ES, Hypermedia API and Ubiquitous unit test project based on EventFlow. It's targeted to ASP.NET Core 2.2 and can be deployed to docker and k8s.
- Based on EventFlow
- Based .NET Core2.2, plan to migrate .NET Core3.1 after EventFlow was fixed
- Implement read model by EntityFramework, MongoDB, Elasticsearch
- Integrate RabbitMQ and used MassTransit as Message bus (in progress)
- Event driven MicroService integration (in progress)
- Wiki is in progress
Then spin up a new container using docker-compose
docker-compose up
Note: add a -d to run the container in background
An API service and mssql will run in docker
This project based on .NET Core SDK 2.2.103, please install corresponding SDK for your operating system:
After installing, please run below command to make sure current .NET Core version is 2.2.103
dotnet --version
The EventStore and ReadModel are based on EF Core and connect to MSSQL, before run this service please update EventStore connect string and
ReadModel connect string in settings.json under RestAirline.Api project.
After set connect string two database will be migrated automatically by the API service.
Journey items should come from another micro-service named flight availability, for now let's build a journey in the api automatically for convenience. So you need not pass any journey id to this api.
POST api/booking/journeys
We can get request body schema from last Api response become the whole Api is designed by Hypermedia.
The api definition is totally described by last api response under resourceCommands\addPassengerCommand:
"addPassengerCommand":
{
"bookingId": "booking-352cb1f3-0f68-4e04-a2f7-24036eb53ce7",
"name": null,
"passengerType": 0,
"age": 0,
"email": null,
"postUrl": {
"uri": "/api/booking/booking-352cb1f3-0f68-4e04-a2f7-24036eb53ce7/passenger"
}
}
Obviously the endpoint is:
http://localhost:61100/api/booking/booking-352cb1f3-0f68-4e04-a2f7-24036eb53ce7/passenger
The payload schema is:
{
"bookingId": "booking-352cb1f3-0f68-4e04-a2f7-24036eb53ce7",
"name": null,
"passengerType": 0,
"age": 0,
"email": null,
}
bookingId is filled already, please try to fill other parameters, eg:
{
"bookingId": "booking-352cb1f3-0f68-4e04-a2f7-24036eb53ce7",
"name": "test",
"passengerType": 0,
"age": 22,
"email": "[email protected]",
}
Send request:
POST api/{bookingId}/passenger
According to response of last api, you can either get the booking by resourceLinks or post data by resourceCommand.
GET api/booking/{bookingId}
