Request Pipeline

Understand the request pipeline around endpoint execution.

The HTTP pipeline receives a request, creates an http.Context, matches an endpoint, runs middleware, and eventually invokes the matched handler delegate.

The important pipeline contract is RequestDelegate:

request.go

type RequestDelegate func(ctx *Context) error

A delegate represents the next step in the pipeline. Middleware can call it to continue, or return early to stop the request.

Middleware

Add cross-cutting behavior before endpoint execution.

Results

Return status, headers, and body values from HTTP handlers.
