how to serve asp.net core Angular SPA over HTTP POST
I am trying to develop an LTI tool using asp.net core and its Angular SPA template. A Learning Management System could use my tool (which is a web app) by embedding an i-frame of it inside their website, and they do so by using an HTTP POST request with additional form-data attached to it. If I would use an asp.net core MVC project, that POST request would reach that same action a GET request would reach and the desired view would render, but with the Angular project template I would arrive to an empty html page with this message
Cannot POST /
I could achieve a work around by adding an action with [Post("/")]
attribute and redirect to the home page by using Redirect("/")
but I was wondering if there's a better solution.

could it be that theCannot POST /
message is coming from express ? I can seex-powered-by: Express
withx-powered-by: ASP.NET
in the response headers... does it make sense?

So I found a better way of getting the page and also preserving the form data.
I just created a custom middleware and changed the POST request to a GET request.
it preserves headers and allows setting cookies, unlike Redirect("/")
app.Use(async (context, next) =>
{
if (context.Request.IsAuthenticatedWithLti())
context.Request.Method = HttpMethods.Get;
await next.Invoke();
});
