(JavaScript) VoiceBase -- Retrieve JSON Transcript

Retrieves a JSON transcript for a media file.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

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

// Insert your Bearer token here:
var accessToken = "VOICEBASE_TOKEN";

var http = new CkHttp();

// Add the access (bearer) token to the request, which is a header
// having the following format:
// Authorization: Bearer <userAccessToken>
var sbAuth = new CkStringBuilder();
sbAuth.Append("Bearer ");
sbAuth.Append(accessToken);
http.SetRequestHeader("Authorization",sbAuth.GetAsString());

var sbUrl = new CkStringBuilder();
sbUrl.Append("https://apis.voicebase.com/v2-beta/media/$MEDIA_ID/transcripts/latest");
var replaceCount = sbUrl.Replace("$MEDIA_ID","f9b9bb88-d52c-4960-bcef-d516a9f85594");

var strJson = http.QuickGetStr(sbUrl.GetAsString());
if (http.LastMethodSuccess !== true) {
    console.log(http.LastErrorText);
    return;
}

// The response should be JSON, even if an error.
var json = new CkJsonObject();
json.Load(strJson);
json.EmitCompact = false;

console.log("Response status code = " + http.LastStatus);

if (http.LastStatus !== 200) {
    console.log(json.Emit());
    console.log("Failed");
    return;
}

// See the sample JSON response below..

// Iterate over the words..
var numWords = json.SizeOfArray("transcripts.latest.words");
var i = 0;
while (i < numWords) {
    json.I = i;
    console.log(json.StringOf("transcripts.latest.words[i].w"));
    i = i+1;
}

console.log("Success.");
