Lua Requires Chilkat v11.0.0+

VoiceBase -- Compound Expression Search

See more VoiceBase Examples

Demonstrates how to do a VoiceBase compound expression search. See VoiceBase Search for more details about Search. Lua

-- This example assumes the Chilkat HTTP API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- Insert your Bearer token here:
local accessToken = "VOICEBASE_TOKEN"

local http = chilkat.Http.new()

local req = chilkat.HttpRequest.new()
req.http_verb = "GET"
req.path = "/v2-beta/media"

-- Add the access (bearer) token to the request, which is a header
-- having the following format:
-- Authorization: Bearer <userAccessToken>
local sbAuth = chilkat.StringBuilder.new()
sbAuth:append("Bearer ")
sbAuth:append(accessToken)
req:add_header("Authorization", sbAuth:get_as_string())

-- Search for media containing the terms any of the terms "test", "number", or "three"
req:add_param("query", "\"test\" OR \"number\" OR \"three\"")

local success = http:http_sreq("apis.voicebase.com", 443, true, req, resp)

-- Examine the response status code and body.

-- The response should be JSON, even if an error.
local json = chilkat.JsonObject.new()

-- A successful response will have a status code = 200

-- See the sample JSON response below..

-- Iterate over the JSON like this:
