I would like to prepend all JSON responses with following string:

What is the best way to achieve this with ASP.NET Core? I would like to have it enabled for all JSON responses automatically.

  • So you want to prevent json hijacking. It may already not be relevant. The idiomatic ASP.NET MVC way to protect from it was JsonRequestBehavior.DenyGet, which was removed from MVC Core, apparently because it is not relevant anymore.

You could use a Middleware that checks the following condition (or whatever condition you need).



if(context.Response.ContentType == "application/json")



Then you just append prepend the context.Response.Body with your string.
