ValidateReqSigHandler

import "github.com/aws/aws-sdk-go/aws/corehandlers"

var ValidateReqSigHandler = request.NamedHandler{
	Name: "core.ValidateReqSigHandler",
	Fn: func(r *request.Request) {
		if r.Config.Credentials == credentials.AnonymousCredentials {
			return
		}
		signedTime := r.Time
		if !r.LastSignedAt.IsZero() {
			signedTime = r.LastSignedAt
		}
		if signedTime.Add(5 * time.Minute).After(time.Now()) {
			return
		}
		fmt.Println("request expired, resigning")
		r.Sign()
	},
}

ValidateReqSigHandler is a request handler to ensure that the request's signature doesn't expire before it is sent. This can happen when a request is built and signed significantly before it is sent. Or significant delays occur when retrying requests that would cause the signature to expire.
