Update

Version 3.0.0

Getting Started

1. Install the standard Nuget package into your Azure Functions application.

Package Manager : Install-Package AzureExtensions.Swashbuckle
CLI : dotnet add package AzureExtensions.Swashbuckle

2. Add Program.cs class on your Functions project.

!!! Now you need to specify in option the RoutePrefix.

        opts.RoutePrefix = "api";

using System;
using System.Collections.Generic;
using Microsoft.Extensions.Hosting;
using System.Reflection;
using AzureFunctions.Extensions.Swashbuckle.Settings;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.OpenApi;
using Microsoft.OpenApi.Models;
using AzureFunctions.Extensions.Swashbuckle;
using Swashbuckle.AspNetCore.SwaggerGen;

var host = new HostBuilder()
    .ConfigureServices((hostContext, services) =>
    {
        //Register the extension
        services.AddSwashBuckle(opts =>
        {
            // If you want to add Newtonsoft support insert next line
            // opts.AddNewtonsoftSupport = true;
            opts.RoutePrefix = "api";
            opts.SpecVersion = OpenApiSpecVersion.OpenApi3_0;
            opts.AddCodeParameter = true;
            opts.PrependOperationWithRoutePrefix = true;
            opts.XmlPath = "TestFunction.xml";
            opts.Documents = new[]
            {
                new SwaggerDocument
                {
                    Name = "v1",
                    Title = "Swagger document",
                    Description = "Swagger test document",
                    Version = "v2"
                },
                new SwaggerDocument
                {
                    Name = "v2",
                    Title = "Swagger document 2",
                    Description = "Swagger test document 2",
                    Version = "v2"
                }
            };
            opts.Title = "Swagger Test";
            //opts.OverridenPathToSwaggerJson = new Uri("http://localhost:7071/api/Swagger/json");
            opts.ConfigureSwaggerGen = x =>
            {
                //custom operation example
                x.CustomOperationIds(apiDesc => apiDesc.TryGetMethodInfo(out MethodInfo methodInfo)
                    ? methodInfo.Name
                    : new Guid().ToString());

                //custom filter example
                //x.DocumentFilter<RemoveSchemasFilter>();

                //oauth2
                x.AddSecurityDefinition("oauth2",
                    new OpenApiSecurityScheme
                    {
                        Type = SecuritySchemeType.OAuth2,
                        Flows = new OpenApiOAuthFlows
                        {
                            Implicit = new OpenApiOAuthFlow
                            {
                                AuthorizationUrl = new Uri("https://your.idserver.net/connect/authorize"),
                                Scopes = new Dictionary<string, string>
                                {
                                    { "api.read", "Access read operations" },
                                    { "api.write", "Access write operations" }
                                }
                            }
                        }
                    });
            };

            // set up your client ID if your API is protected
            opts.ClientId = "your.client.id";
            opts.OAuth2RedirectPath = "http://localhost:7071/api/swagger/oauth2-redirect";
        });
    })
    .Build();

host.Run();

3. Add swagger and swagger ui endpoint functions on your project.

    public class SwaggerController
    {
        private readonly ISwashBuckleClient swashBuckleClient;

        public SwaggerController(ISwashBuckleClient swashBuckleClient)
        {
            this.swashBuckleClient = swashBuckleClient;
        }

        [SwaggerIgnore]
        [Function("SwaggerJson")]
        public async Task<HttpResponseData> SwaggerJson(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = "Swagger/json")]
            HttpRequestData  req)
        {
            return await this.swashBuckleClient.CreateSwaggerJsonDocumentResponse(req);
        }

        [SwaggerIgnore]
        [Function("SwaggerYaml")]
        public async Task<HttpResponseData> SwaggerYaml(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = "Swagger/yaml")]
            HttpRequestData req)
        {
            return await this.swashBuckleClient.CreateSwaggerYamlDocumentResponse(req);
        }

        [SwaggerIgnore]
        [Function("SwaggerUi")]
        public async Task<HttpResponseData> SwaggerUi(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = "Swagger/ui")]
            HttpRequestData req)
        {
            return await this.swashBuckleClient.CreateSwaggerUIResponse(req, "swagger/json");
        }

        /// <summary>
        /// This is only needed for OAuth2 client. This redirecting document is normally served
        /// as a static content. Functions don't provide this out of the box, so we serve it here.
        /// Don't forget to set OAuth2RedirectPath configuration option to reflect this route.
        /// </summary>
        /// <param name="req"></param>
        /// <param name="swashBuckleClient"></param>
        /// <returns></returns>
        [SwaggerIgnore]
        [Function("SwaggerOAuth2Redirect")]
        public async Task<HttpResponseData> SwaggerOAuth2Redirect(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = "swagger/oauth2-redirect")]
            HttpRequestData req)
        {
            return await this.swashBuckleClient.CreateSwaggerOAuth2RedirectResponse(req);
        }
    }

4. Open Swagger UI URL in your browser.

If you does not changed api route prefix. Swagger UI URL is https://hostname/api/swagger/ui .

Options

Include Xml document file

AzureFunctions.Extensions.Swashbuckle can include xml document file.

1. Change your functions project's GenerateDocumentationFile option to enable.

        builder.AddSwashBuckle(Assembly.GetExecutingAssembly(), opts =>
        {
            opts.XmlPath = "TestFunction.xml";
        });
   

2. Add configration setting this extensions on your functions project's local.settings.json

  "SwaggerDocOptions": {
    "XmlPath": "TestFunction.xml"
  }

Alternatively you can add this section to your host.json

  "extensions": {
    "Swashbuckle": {
      "XmlPath": "TestFunction.xml"
    }
  }
