How to map internal endpoint in Ocelot API gateway?

[lujamaharjan]

When i use
await app.UseOcelot()
The endpoints in the same project where ocelot is configured do not work. I get 404. Is there any way to map internal routes.

Hello, Sachin!

What endpoints are you referring to? How were they established? What is the actual type of the 404 error? Could you please extract the logs?

Did you mean the Ocelot controller endpoints or user type ones? Could you provide the complete C# code?

using DMNMiddleware.APIGateway;
using DMNMiddleware.APIGateway.Services;
using Microsoft.IdentityModel.Tokens;
using Ocelot.DependencyInjection;
using Ocelot.Middleware;
using Scalar.AspNetCore;

var builder = WebApplication.CreateBuilder(args);
builder.Configuration
    .SetBasePath(Directory.GetCurrentDirectory()) 
    .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true) 
    .AddJsonFile($"appsettings.{builder.Environment.EnvironmentName}.json", optional: true) 
    .AddEnvironmentVariables();

builder.Configuration.AddJsonFile("ocelot.json");

var app = builder.Build();
app.MapGet("/test", () => "Hello World!");
await app.UseOcelot();
app.Run();

I get 404 while browsing /test. how can I include /test as routing.

This is sample code. when I add app.Mapget and make API in this page I am getting 404

I'm curious about the necessity for additional controllers in a product whose primary function is to forward API requests. If research is required, please conduct it independently.
Please find another public GitHub repository for some fun❗

so, write now, it does not support minimal API and ocelot in same asp.net project?

You should Map controller routes after UseOcelot, not before!

var app = builder.Build();
await app.UseOcelot(); // before your custom MapGet
app.MapGet("/test", () => "Hello World!");
app.Run();

Hope it helps!

hi, the endpoint after UseOcelot() also not worked. For /test also, ocelot is trying to find downstream url.
