Answer 1

By the time it gets to your middleware the request stream has already been read, so what you can do here is Microsoft.AspNetCore.Http.Internal.EnableRewind on the Request and read it yourself

Site wide :

Startup.cs
using Microsoft.AspNetCore.Http.Internal;

Startup.Configure(...){
...
//Its important the rewind us added before UseMvc
app.Use(next => context => { context.Request.EnableRewind(); return next(context); });
app.UseMvc()
...
}

OR selective :

private async Task GenerateToken(HttpContext context)
    {
     context.Request.EnableRewind();
     string jsonData = new StreamReader(context.Request.Body).ReadToEnd();
    ...
    }
