You can add it in an IComposer. It will automatically be picked up when the site starts, and from there you can do what you would do in Program.cs https://docs.umbraco.com/umbraco-cms/implementation/composing

Thank you, @skttl. Already tested the filtering below but didn't work!

Copy code

// CorsComposer.cs
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.DependencyInjection;

public class CorsComposer : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        builder.Services.AddCors(options =>
        {
            options.AddPolicy("AstraCorsPolicy", builder =>
            {
                builder.WithOrigins("https://192.168.1.12:5001") // Specify allowed origins
                       .AllowAnyMethod()
                       .AllowAnyHeader();
            });
        });
    }
}

Copy code

//CorsMiddlewareComposer.cs
using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.DependencyInjection;
using Microsoft.Extensions.DependencyInjection;

public class CorsMiddlewareComposer : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        builder.Services.AddTransient<IStartupFilter, CorsStartupFilter>();
    }
}

public class CorsStartupFilter : IStartupFilter
{
    public Action<IApplicationBuilder> Configure(Action<IApplicationBuilder> next)
    {
        return app =>
        {
             // Ensure CORS is applied between UseRouting and UseEndpoints
            app.UseRouting();

            app.UseCors("AstraCorsPolicy");

            next(app); 
        };
    }
}

Copy code

//AstraController.cs
using Microsoft.AspNetCore.Mvc;
using Umbraco.Cms.Core.Services;
using Umbraco.Cms.Web.Common.Controllers;
using System;
using System.Collections.Generic;
using System.Linq;
using Umbraco.Cms.Core.Models;
using Umbraco.Cms.Core.Models.PublishedContent;
using Microsoft.AspNetCore.Cors;
using Microsoft.AspNetCore.Authorization;

namespace Astra.Controllers
{
    [EnableCors("AstraCorsPolicy")]
    public class AstraController : UmbracoApiController
    {...

Check the docs 🙂 You add middleware by configuring UmbracoPipelineOptions https://docs.umbraco.com/umbraco-cms/reference/routing/custom-middleware
