NSwag

Installation

Powershell.svg 
# pour vscode
dotnet add package NSwag.AspNetCore
# Add to the project file *.csproj:
#  <ItemGroup> 
#    <PackageReference Include="NSwag.AspNetCore" Version="11.17.15" />

Configuration

Configuration Web API

Startup.cs 
public void ConfigureServices(IServiceCollection services)
{
    services.AddSwaggerDocument();

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseOpenApi();
    app.UseSwaggerUi3();

Configuration MVC

Startup.cs 
using NJsonSchema;
using NSwag.AspNetCore;
using System.Reflection;

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseMvc();

    // à ajouter avant app.UseSpa
    app.UseSwaggerUi(typeof(Startup).GetTypeInfo().Assembly, settings =>
    {
        settings.GeneratorSettings.DefaultPropertyNameHandling = PropertyNameHandling.CamelCase;
        settings.PostProcess = document =>
        {
            //document.Info.Version = "v1";
            document.Info.Title = "Test API";
            document.Info.Description = "A simple ASP.NET Core web API";
            //document.Info.TermsOfService = "None";
            document.Info.Contact = new NSwag.SwaggerContact
            {
                Name = "Nicolas",
                //Email = string.Empty,
                //Url = "https://twitter.com/spboyer"
            };
            /*document.Info.License = new NSwag.SwaggerLicense
            {
                Name = "Use under LICX",
                Url = "https://example.com/license"
            };*/
        };
    });

Problème avec IActionResult

NSwag utilise la réflexion pour obtenir le type de retour. Avec IActionResult il ne peut pas.

Csharp.svg 
[HttpGet]
// utiliser SwaggerResponse
[SwaggerResponse(HttpStatusCode.OK, typeof(IReadOnlyList<ItemDto>))]
[SwaggerResponse(HttpStatusCode.BadRequest, typeof(void))]
// ou ProducesResponseType
[ProducesResponseType(typeof(IReadOnlyList<ItemDto>), StatusCodes.Status200OK)]
public IActionResult Get()

Swashbuckle

Swashbuckle installation

Already installed in .NET 7+

MyWebApi.csproj 
<ItemGroup>
  <PackageReference Include="Swashbuckle.AspNetCore" Version="6.4.0" />
</ItemGroup>
Program.cs 
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

Installation Old

Bash.svg 
dotnet add package Swashbuckle.AspNetCore
Startup.cs 
public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers();
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "EFWebApi", Version = "v1" });
    });
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseSwagger();
        app.UseSwaggerUI(c => 
        {
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "EFWebApi v1");
            c.RoutePrefix = string.Empty;  // serve the Swagger UI at the app's root (http://localhost:<port>/)
        });
    }

Usage

Controllers/ItemController.cs 
[ApiController]
[Route("[controller]")]
[Produces("application/json")]  // set the Media type
public class ItemController : ControllerBase
{
    [HttpGet]
    [ProducesResponseType(typeof(IEnumerable<Item>), StatusCodes.Status200OK)]  // set the status code and the return type
    public IActionResult Get() { /* ... */ }
}

XML documentation

MyProject.csproj 
<PropertyGroup>
  <GenerateDocumentationFile>true</GenerateDocumentationFile>
  <NoWarn>$(NoWarn);1591</NoWarn>
</PropertyGroup>
Program.cs 
builder.Services.AddSwaggerGen(
    options =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "My Web Api", Version = "v1" });

        // Set the comments path for the Swagger JSON and UI.
        var xmlFilename = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
        options.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, xmlFilename));
    });
}
Controllers/ItemController.cs 
/// <summary>Fetch all the items.</summary>

public IActionResult GetAll() { /* ... */ }

Dark theme

Paramètres optionnels

Swagger ne gère pas les paramètres optionnels s'ils font partie du chemin, il les considère comme des paramètres required.
