Todo el middleware principal reside en el paquete middleware:

import "github.com/labstack/echo/v5/middleware"

Uso

e := echo.New()
e.Use(middleware.BodyDump(func(c *echo.Context, reqBody, resBody []byte, err error) {
  // Handle the request and response bodies.
}))

Configuración personalizada

e := echo.New()
e.Use(middleware.BodyDumpWithConfig(middleware.BodyDumpConfig{}))

Campos del código fuente
Campo	Tipo	Descripción	Fuente
`Skipper`	`Skipper`	Skipper defines a function to skip middleware.	L21
`Handler`	`BodyDumpHandler`	Handler receives request, response payloads and handler error if there are any. Required.	L25
`MaxRequestBytes`	`int64`	MaxRequestBytes limits how much of the request body to dump. If the request body exceeds this limit, only the first MaxRequestBytes are dumped. The handler callback receives truncated data. The next handler still receives the full request body. Default: 5 * MB (5,242,880 bytes) Set to -1 to disable limits (not recommended in production).	L33
`MaxResponseBytes`	`int64`	MaxResponseBytes limits how much of the response body to dump. If the response body exceeds this limit, only the first MaxResponseBytes are dumped. The handler callback receives truncated data. Default: 5 * MB (5,242,880 bytes) Set to -1 to disable limits (not recommended in production).	L40
