Swagger/OpenAPI –part 16

In order to see the WebAPI, Swagger is a default technology. Reading https://docs.microsoft.com/en-us/aspnet/core/tutorials/web-api-help-pages-using-swagger?view=aspnetcore-3.0 , seems to have 2 options: Swashbuckle and NSwag. Looking at github repositories, both have > 2k stars, active development, tutorials. The only thing that I see more at NSwag are generators for Angular.

Integrated NSwag as for the tutorial from https://docs.microsoft.com/en-us/aspnet/core/tutorials/getting-started-with-nswag?view=aspnetcore-3.0&tabs=visual-studio . There is a small problem – when I try the swagger , I should put explicit the version. However, a not experienced user can not see this value.

Trying to put documentation : when I go to Project=>Properties=>Build and click the XML documentation, shows the full path to the XML. I do not need this!  So I edit the .csproj directly and change from full path to file

Also, because I want to be sure to have documentation, I change “warnings to errors”.

So now I must document Program and main(removed public from startup.cs and createwebhost – to not document)

Total: 6 changes , https://github.com/ignatandrei/InfoValutar/commit/4fbff903c4510acbcb219d0263ae89736e9f2d8d

So now I can browse to swagger

However, I should indicate to people that swagger is enabled to invite them browse to this – and this is easy to do in Kestrel, right ? Just take the address of the url …

So, trying in Program.cs to find the adresses:

var build = CreateHostBuilder(args).Build();
var s = build.Services.GetService(typeof(KestrelServerOptions));
var s1 = build.Services.GetService(typeof(IServer));
var s2 = build.Services.GetService(typeof(IServerAddressesFeature));


Not a chance – not yet configured. So , next chance is in Startup.cs

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
//other code
var sa = app.ServerFeatures.Get<IServerAddressesFeature>();
var urls =string.Join(",", sa.Addresses.Select(it => it + "swagger"));
Console.WriteLine("please use " + urls);

( for this, you must not use IIS Express, but rather the project)

And one hour passes...
(This is the result of 1 hour per day auto-challenge as a full cycle developer for an exchange rates application)
