json NSE Library — Nmap Scripting Engine documentation (original) (raw)
Library methods for handling JSON data. It handles JSON encoding and decoding according to RFC 4627.
There is a straightforward mapping between JSON and Lua data types. One exception is JSON NULL, which is not the same as Luanil. (A better match for Lua nil is JavaScriptundefined.) NULL values in JSON are represented by the special value json.NULL.
