How to use

Middlewares

GroupNameKeyAuthorizationMiddleware

This middleware is used to block access to an OpenAPI document or specification by using a pre-shared key that must be provided in the request header per specification.

To configure, use the GroupNameKeyAuthenticationOptions class.

When requesting an OpenAPI specification, identified by its group name, the client must provide the pre-shared key in the request header. Otherwise, the request will fail with an HTTP 401 UNAUTHORIZED response.

Extensions

IApplicationBuilderExtensions

The IApplicationBuilderExtensions is a static class that provides extension methods for IApplicationBuilder, usually to add and configure middlewares.

Using it is quite simple, just get an instance of an IApplicationBuilder and call any of the available extension methods.

var builder = WebApplication.CreateBuilder(new WebApplicationOptions()
{
    ContentRootPath = Directory.GetCurrentDirectory(),
});

// ...

var app = builder.Build();

app.UseSwaggerGroupNameKeyAuthorization(options =>
{
    // Enable only if not in Development environment. Allow developers to test without keys...
    options.IsEnabled = !builder.Environment.IsDevelopment(); 
});

// ...

Currently, available extension methods are:

• UseSwaggerGroupNameKeyAuthorization(this IApplicationBuilder app, SwaggerGroupNameKeyAuthenticationOptions options): adds the GroupNameKeyAuthorizationMiddleware middleware using provided options.
• UseSwaggerGroupNameKeyAuthorization(this IApplicationBuilder app, Action<SwaggerGroupNameKeyAuthenticationOptions>? setupAction = null): adds the GroupNameKeyAuthorizationMiddleware middleware configuring options inline.

Important: Make sure that UseSwaggerGroupNameKeyAuthorization is added before any UseSwagger(), UseSwaggerUI(), or any other OpenAPI implementation middleware call, so that authorization middleware is called before accessing the OpenAPI document.
