#5 WebApi - Bare Metal for custom requests
Bare Metal WebAPI Commands (v12.10+)
In some cases you want to have more control over the API calls, but still need 2sxc to help you get the right headers and urls.
This is what we call the Bare Metal WebApi since it gives you the stuff so you can do the work yourself.
As with everything, you usually need to get the module sxc
controller first, so that the values you get match your app and use case.
In these examples, we're using the current HTML-node to find the sxc
controller,
but there are other ways as well if you prefer working the the Module Id.
Headers
This will show you the headers which will probably be needed for a request:
<script>
function showHeaders(moduleContext, optionalVerb) {
var headers = $2sxc(moduleContext).webApi.headers(optionalVerb);
alert('These are the headers used if the verb is "' + (optionalVerb ?? '') + '":\n'
+ JSON.stringify(headers, null, 2));
}
</script>
URL
Resolve URLs to endpoints and similar
<script>
function showUrl(moduleContext, url) {
var finalUrl = $2sxc(moduleContext).webApi.url(url);
alert('These is the full url for "' + url + '":\n' + finalUrl);
}
</script>

Info about the Base Class
This tutorial inherits from the Custom.Hybrid.Razor14 base class.
This allows us to use Kit.Page to access IPageService without having to use GetService<>
@inherits Custom.Hybrid.Razor14
@{
// Tell the page that we need the 2sxc Js APIs
Kit.Page.Activate("2sxc.JsCore");
}

Note about Hybrid WebAPIs
These examples are all done to work in both Dnn ☢️ and Oqtane 💧.
Because of this, the Api Controller have special conditional statements like
#if NETSTANDARD
which uses different namespaces in .net core and .net Framework.
If you only target Dnn
or Oqtane, you can remove the lines you don't need.
See
See how to use #if
// Add namespaces for security check in Oqtane & DNN despite differences in .net core/.net Framework
// If you only target one platform, you can remove the parts you don't need
#if NETCOREAPP
using Microsoft.AspNetCore.Authorization; // .net core [AllowAnonymous] & [Authorize]
using Microsoft.AspNetCore.Mvc; // .net core [HttpGet] / [HttpPost] etc.
#else
using System.Web.Http; // .net 4.5 [AllowAnonymous] / [HttpGet]
using DotNetNuke.Web.Api; // [DnnModuleAuthorize] & [ValidateAntiForgeryToken]
#endif
[AllowAnonymous] // all commands can be accessed without a login
[ValidateAntiForgeryToken] // protects API from users not on your site (CSRF protection)
public class VerifiedController : Custom.Hybrid.Api14 // see https://r.2sxc.org/CustomWebApi
{
[HttpGet] // [HttpGet] says we're listening to GET requests
public string Hello()
{
return "Hello from the controller with ValidateAntiForgeryToken in /api";
}
}
// The next line is for 2sxc-internal quality checks, you can ignore this
