URL Encoding and Decoding

See more Encryption Examples

Demonstrates URL encoding and decoding. Lua

local chilkat = require("chilkat")

-- To URL encoding a string:
local s = "Why a > b?"

local sb = chilkat.StringBuilder.new()
local success = sb:append(s)

-- URL encode the string.
sb:encode("url", "utf-8")

-- Show the URL encoded string:
local sEncoded = sb:get_as_string()
print(sEncoded)

-- The result is:  Why%20a%20%3E%20b%3F

-- If you prefer "+" instead of "%20" for SPACE chars:
local numReplaced = sb:replace("%20", "+")
print(sb:get_as_string())

-- Output is:   Why+a+%3E+b%3F

-- To decode:
sb:decode("url", "utf-8")
print(sb:get_as_string())

-- Result is: Why a > b?
