Delegate CallNextHandlerDelegate

Invokes the next compatible handler in the current routing pipeline.

Namespace: NanoRoute

Assembly: NanoRoute.dll

Syntax

public delegate Task<HttpResponseMessage> CallNextHandlerDelegate()

Returns

Type	Description
Task<HttpResponseMessage>	The HttpResponseMessage produced by the next matching handler.

Remarks

This delegate is passed into RequestHandlerDelegate so handlers can opt into middleware-style composition. When the current handler does not call it, the pipeline stops at the current handler. Matching continues only within the route branch already selected for the request; sibling branches are not revisited.

Examples

routerBuilder.AddHandler("GET", "/api/users/{id:int}", async (requestContext, callNext) =>
{
    requestContext.Parameters["StartTime"] = DateTimeOffset.UtcNow;
    return await callNext();
});
