I need to pass some parameters from middleware to controller and I'm confused which approach should I use if I have to take care of performance, resource usage and security.
context.Items["user-id"] = "12345";context.Session.SetInt32("user-id", 12345);(It is the requirement to keep the Session enabled anyway.)
You could pass it as an http header down the pipeline with the request
public class UserHeaderMiddleware
{
private readonly RequestDelegate _next;
public UserHeaderMiddleware(RequestDelegate next)
{
_next = next;
}
public async Task Invoke(HttpContext context)
{
context.Request.Headers.Add("user-id", new[] { userId.ToString() });
await _next(context);
}
}
If you need to store the user ID for the future, session is the way to go. Items only passes it along for that request.
