Lua Requires Chilkat v11.0.0+

VoiceBase -- Upload a media file for transcription and analysis

See more VoiceBase Examples

This example demonstrates how to upload a media file for transcription and analysis. It duplicates the following curl command:

curl https://apis.voicebase.com/v2-beta/media \
  --form media=@msg_123_abc.wav \
  --header "Authorization: Bearer ${TOKEN}"

Lua

local chilkat = require("chilkat")

-- 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 = "POST"
req.path = "/v2-beta/media"
req.content_type = "multipart/form-data"

-- 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())

local success = req:add_file_for_upload2("media", "qa_data/wav/msg_123_abc.wav", "audio/x-wav")
if not success then
    print(req.last_error_text)
    return
end

local resp = chilkat.HttpResponse.new()
success = http:http_sreq("apis.voicebase.com", 443, true, req, resp)
if not success then
    print(http.last_error_text)
    return
end

-- Examine the response status code and body.
print("Response status code = " .. resp.status_code)

-- The response should be JSON, even if an error.
local json = chilkat.JsonObject.new()
json:load(resp.body_str)
json.emit_compact = false

print(json:emit())

-- A successful response will have a status code = 200
if resp.status_code ~= 200 then
    print("Failed.")
else
    print("mediaId: " .. json:string_of("mediaId"))
    print("href: " .. json:string_of("_links.self.href"))
    print("status: " .. json:string_of("status"))
    print("Success.")
end

-- Here is an example of a successful response:

--     {
--       "_links": {
--         "self": {
--           "href": "/v2-beta/media/856a1e85-c847-4c3c-b7a4-6cf15cd51db4"
--         }
--       },
--       "mediaId": "856a1e85-c847-4c3c-b7a4-6cf15cd51db4",
--       "status": "accepted",
--       "metadata": {}
--     }
