OAuth2 authentication redirect page isn't served

[sunpeinju]

When doing OAuth2 authentication from swagger-ui, the OAuth server will do user authorization and return the result to swagger (Koa) server's /oauth2-redirect.html endpoint. koa2-swagger-ui doesn't handle this endpoint, so authorization fails.

• 'oauth2-redirect.html' page is part of 'swagger-ui-dist', it's not available through cdn https://cdnjs.cloudflare.com/ajax/libs/swagger-ui/3.20.0/.
• Why does this lib choose to serve swagger-ui resources through cdn? Could it directly uses resources from swagger-ui-dist?

BTW, currently I'm using koa-send in my app to serve the missing page:

• 'my_redirect_uri' is my server's oauth callback endpoint.
• the endpoint is passed to swagger-ui through oauth2RedirectUrl option.
• add route for 'my_redirect_uri' and send the '/oauth2-redirect.html' page to browser.

app.use(koaSwagger({
  oauthOptions: {...},
  swaggerOptions: {
    oauth2RedirectUrl: my_redirect_uri,
  }
}));

const router = new Router();
router.get(my_redirect_uri, async (ctx) => {
  await send(ctx, '/oauth2-redirect.html', { root: swagger.getAbsoluteFSPath() });
});
app.use(router.routes());

its using the cdn because, for our use case, the server was a raspberry pi and it was really slow at serving large blobs because it couldn't compress them quickly and the network isn't great. probably open to a pr

it could be fine if 'oauth2-redirect.html' is also available through cdn. Don't know how to do that.

This needs to be handled. The issue does not exist in e.g. Swagger editor.
