ASP.NET Core & Swagger : generate multiple outputs

Question

I'm using ASP.NET Core with Swashbuckle.AspNetCore.SwaggerGen in version v6.1.5.

I want routes like [HttpGet] or [HttpGet("user")] in a public swagger.json for public endpoints and other routes that contain internal inside the route like this [HttpGet("internal/user/{userGuid}")] to be in an internal instance of swagger.json endpoints.

I configure Swagger in startup in ConfigureServices like this:

services.AddSwaggerGen(gen =>
{
    gen.SwaggerDoc("v1", new OpenApiInfo
    {
        Title = "Server API",
        Version = "1.0",
        Description = "This API features all public available endpoints showing different API features."
    });
    gen.SwaggerDoc("v1-internal", new OpenApiInfo
    {
        Title = "Viewer Server API (internal)",
        Version = "v1-internal",
        Description = "This API features all public available endpoints showing different API features."
    });
});

and in Configure

app.UseSwagger();
app.UseSwaggerUI(c =>
{
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "Viewer Server API v1");
    c.SwaggerEndpoint("/swagger/v1-internal/swagger.json", "Viewer Server API v1 (internal)");
});

How can I get it to create a public and an internal swagger.json?

Is [this](https://stackoverflow.com/a/49613813/1752270) what you want? — AndrewSilver, Aug 29 '21 at 16:12
@AndrewSilver I'm don't get where the sorting happens, see updated question. — user3079834, Aug 29 '21 at 18:57

Filtering different version or in my case "visibility-layer" can be done like the follwing. Configure Swagger in startup in ConfigureServices like this:

services.AddSwaggerGen(gen =>
{
    gen.SwaggerDoc("v1", new OpenApiInfo
    {
        Title = "Server API",
        Version = "1.0",
        Description = "This API features all public available endpoints showing different API features."
    });
    gen.SwaggerDoc("v1-internal", new OpenApiInfo
    {
        Title = "Viewer Server API (internal)",
        Version = "v1-internal",
        Description = "This API features all public available endpoints showing different API features."
    });

    gen.DocInclusionPredicate((docName, apiDesc) =>
    {
        if (docName.Contains("internal"))
        {
            return apiDesc.RelativePath.Contains("internal/");
        }
        else
        {
            return !apiDesc.RelativePath.Contains("internal/");
        }
    });
});

and in Configure

app.UseSwagger();
app.UseSwaggerUI(c =>
{
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "Viewer Server API v1");
    c.SwaggerEndpoint("/swagger/v1-internal/swagger.json", "Viewer Server API v1 (internal)");
});

And now you can choose different configurations like in the image below:
