VoiceBase -- Retrieve JSON Transcript

See more VoiceBase Examples

Retrieves a JSON transcript for a media file. Rust

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

// Insert your Bearer token here:
let access_token = "VOICEBASE_TOKEN".to_string();

let http = chilkat::Http::new();

// Add the access (bearer) token to the request, which is a header
// having the following format:
// Authorization: Bearer <userAccessToken>
let sb_auth = chilkat::StringBuilder::new();
let _ = sb_auth.append("Bearer ");
let _ = sb_auth.append(&access_token);
http.set_request_header("Authorization", &sb_auth.get_as_string().unwrap_or_default());

let sb_url = chilkat::StringBuilder::new();
let _ = sb_url.append("https://apis.voicebase.com/v2-beta/media/$MEDIA_ID/transcripts/latest");
let replace_count = sb_url.replace("$MEDIA_ID", "f9b9bb88-d52c-4960-bcef-d516a9f85594");

let Ok(str_json) = http.quick_get_str(&sb_url.get_as_string().unwrap_or_default()) else {
    println!("{}", http.last_error_text());
    return;
};

// The response should be JSON, even if an error.
let json = chilkat::JsonObject::new();
let _ = json.load(&str_json);
json.set_emit_compact(false);

println!("Response status code = {}", http.last_status());

if http.last_status() != 200 {
    println!("{}", json.emit().unwrap_or_default());
    println!("Failed");
    return;
}

// See the sample JSON response below..

// Iterate over the words..
let num_words = json.size_of_array("transcripts.latest.words");
let mut i = 0;
while i < num_words {
    json.set_i(i);
    println!("{}", json.string_of("transcripts.latest.words[i].w").unwrap_or_default());
    i = i + 1;
}

println!("Success.");
