urlshort/v0 package

Overview

Package urlshort is a simple on-chain URL alias registry.

Callers register an `alias -> url` mapping they own. An alias can only be claimed once; the owner may later update the target URL, but nobody else can overwrite an alias they do not own. A per-alias click counter is bumped every time the alias is resolved through Render("/<alias>").

Function

Shorten

func Shorten(cur realm, alias string, url string, note string)

Shorten registers `alias -> url` owned by the caller.

Rules:

  • alias must be non-empty and alphanumeric;
  • url must be non-empty;
  • if the alias is unclaimed, it is created owned by the caller;
  • if it is already claimed by the caller, the url/note are updated;
  • if it is claimed by someone else, the call aborts.
