Function TerminatedPathBefore

app/api/middleware/encode/encode.go:125–145

TerminatedPathBefore wraps an http.HandlerFunc in a layer that encodes a terminated path (e.g. "/space1/space2/+") before executing the provided http.HandlerFunc. The first prefix that matches the URL.Path will be used during encoding (prefix is ignored during encoding).

(prefixes []string, next http.Handler)

// before executing the provided http.HandlerFunc. The first prefix that matches the URL.Path will
// be used during encoding (prefix is ignored during encoding).
func TerminatedPathBefore(prefixes []string, next http.Handler) http.Handler {
	return http.HandlerFunc(
		func(w http.ResponseWriter, r *http.Request) {
			ctx := r.Context()
			for _, p := range prefixes {
				changed, err := pathTerminatedWithMarker(r, p, "/+", "")
				if err != nil {
					render.TranslatedUserError(ctx, w, err)
					return
				}

				// first prefix that leads to success we can stop
				if changed {
					break
				}
			}

			next.ServeHTTP(w, r)

// TerminatedRegexPathBefore is similar to TerminatedPathBefore but supports regex prefixes.
