Use Superscribe.Owin Package in Web API

Introduction

In this article I will use the "Superscribe.Owin" package in the ASP.NET Web API. We use the package for determine what the web framework contributes. Superscribe is a module for the router handler. It is a way to map between the media types and serialiser.

Step 4

There is a class named "Startup.cs".

Add the following code to it:

using Superscribe.Owin;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace SuperOwin
{
public class Startup
{
public void Configuration(IAppBuilder ibuild)
{
var Con = new SuperscribeOwinConfig();
Con.MediaTypeHandlers.Add(
"text/html",
new MediaTypeHandler { Write = (rslt, o) => rslt.WriteAsync(o.ToString()) });
ibuild.UseSuperscribeModules(Con);
}
}
}

Step 5

Add a new class as in the following:

In the Solution Explorer.
Right-click on the "SuperOwin" project name.
Select "Add" -> "Class".

create Class

Add the folowing code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Superscribe.Owin;
namespace SuperOwin
{
public class Hello: SuperscribeOwinModule
{
public Hello()
{
this.Get["/"] = _ => "This is the example of Superscribe Owin:";
}
}
}

Step 6

Now in the Web.config file we ensure that it handles the OWIN request:

<appSettings>
<add key="owin:HandleAllRequests" value="true" />
<add key="owin:SetCurrentDirectory" value="true" />
</appSettings>
