Add support for Microsoft HTTP Resilience library

christianhelle commented 2 weeks ago

Previously, the UsePolly setting was used for transient fault handling in the dependency injection settings. This pull request updates the code to use the new TransientErrorHandler property instead. The UsePolly setting is deprecated and will be removed in future versions. This change improves the clarity and maintainability of the code.

The following code is generated:

namespace Petstore
{
    using System;
    using Microsoft.Extensions.DependencyInjection;
    using Microsoft.Extensions.Http.Resilience;

    public static partial class IServiceCollectionExtensions
    {
        public static IServiceCollection ConfigureRefitClients(this IServiceCollection services, Action<IHttpClientBuilder>? builder = default)
        {
            var clientBuilderISwaggerPetstoreDirect = services
                .AddRefitClient<ISwaggerPetstoreDirect>()
                .ConfigureHttpClient(c => c.BaseAddress = new Uri("https://petstore3.swagger.io/api/v3"));

            clientBuilderISwaggerPetstoreDirect
                .AddStandardResilienceHandler(config =>
                {
                    config.Retry = new HttpRetryStrategyOptions
                    {
                        UseJitter = true,
                        MaxRetryAttempts = 3,
                        Delay = TimeSpan.FromSeconds(0.5)
                    };
                });

            builder?.Invoke(clientBuilderISwaggerPetstoreDirect);

            return services;
        }
    }
}

using the following .refitter file

{
  "openApiPath": "./OpenAPI/v3.0/petstore.json",
  "dependencyInjectionSettings": {
    "baseUrl": "https://petstore3.swagger.io/api/v3",
    "transientErrorHandler": "HttpResilience",
    "maxRetryCount": 3,
    "firstBackoffRetryInSeconds": 0.5
  }
}
