Sure! Below is the complete setup for handling multiple endpoints with different JSON responses in an ASP.NET Core Web API project using .NET 8 and Ocelot.
- Create a new ASP.NET Core Web API project.
- Define the Article model and controller.
// Models/Article.cs
public class Article
{
public int Id { get; set; }
public string Title { get; set; }
public string Content { get; set; }
}
// Controllers/ArticlesController.cs
[ApiController]
[Route("api/[controller]")]
public class ArticlesController : ControllerBase
{
private static readonly List<Article> Articles = new()
{
new Article { Id = 1, Title = "Article 1", Content = "Content 1" },
new Article { Id = 2, Title = "Article 2", Content = "Content 2" }
};
[HttpGet]
public IActionResult GetArticles() => Ok(Articles);
}- Create another ASP.NET Core Web API project.
- Define the Writer model and controller.
// Models/Writer.cs
public class Writer
{
public int Id { get; set; }
public string Name { get; set; }
public string Bio { get; set; }
}
// Controllers/WritersController.cs
[ApiController]
[Route("api/[controller]")]
public class WritersController : ControllerBase
{
private static readonly List<Writer> Writers = new()
{
new Writer { Id = 1, Name = "Writer 1", Bio = "Bio 1" },
new Writer { Id = 2, Name = "Writer 2", Bio = "Bio 2" }
};
[HttpGet]
public IActionResult GetWriters() => Ok(Writers);
}-
Create a new ASP.NET Core Web API project for the API Gateway.
-
Install the Ocelot package:
dotnet add package Ocelot -
Configure
ocelot.jsonfor routing:
{
"Routes": [
{
"UpstreamPathTemplate": "/gateway/articles",
"DownstreamPathTemplate": "/api/articles",
"DownstreamHostAndPorts": [
{
"Host": "localhost",
"Port": 7201
}
]
},
{
"UpstreamPathTemplate": "/gateway/writers",
"DownstreamPathTemplate": "/api/writers",
"DownstreamHostAndPorts": [
{
"Host": "localhost",
"Port": 7265
}
]
}
],
"GlobalConfiguration": {
"BaseUrl": "http://localhost:7152"
}
}- Configure
Program.csto use Ocelot:
using Ocelot.DependencyInjection;
using Ocelot.Middleware;
var builder = WebApplication.CreateBuilder(args);
builder.Configuration.AddJsonFile("ocelot.json", optional: false, reloadOnChange: true);
builder.Services.AddOcelot();
var app = builder.Build();
await app.UseOcelot();
app.Run();-
Set up the solution to run all three projects (Article.Api, Writer.Api, and API Gateway) simultaneously.
-
Ensure each project runs on its designated port:
- Article.Api: http://localhost:7201
- Writer.Api: http://localhost:7265
- API Gateway: http://localhost:7152
-
Test the endpoints:
This setup routes requests through the API Gateway to the respective microservices, handling different JSON endpoints effectively.
