Add a Query Parameter from a StringBuilder

See more REST Examples

Demonstrates Rest.AddQueryParamSb, which adds or replaces a query parameter whose value is read from a StringBuilder. The 1st argument is the name and the 2nd is the StringBuilder.

Background. This variant is convenient when the parameter value has already been assembled in a StringBuilder, avoiding an extra conversion to a plain string.

local chilkat = require("chilkat")

local rest = chilkat.Rest.new()

-- Connect to the REST server.  The 3rd argument enables TLS (use true for HTTPS on port 443),
-- and the 4th enables automatic reconnection if the connection is dropped between requests.
local bTls = true
local bAutoReconnect = true
local success = rest:connect("example.com", 443, bTls, bAutoReconnect)
if not success then
    print(rest.last_error_text)

-- The parameter value can also be supplied from a StringBuilder.  The 1st argument is the name and
-- the 2nd is the StringBuilder holding the value.
