(C# UWP/WinRT) VoiceBase -- Upload a media file for transcription and analysis

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}"

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

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

Chilkat.Http http = new Chilkat.Http();

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.HttpVerb = "POST";
req.Path = "/v2-beta/media";
req.ContentType = "multipart/form-data";

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

bool success = req.AddFileForUpload2("media","qa_data/wav/msg_123_abc.wav","audio/x-wav");
if (success != true) {
    Debug.WriteLine(req.LastErrorText);
    return;
}

Chilkat.HttpResponse resp = await http.SynchronousRequestAsync("apis.voicebase.com",443,true,req);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// Examine the response status code and body.
Debug.WriteLine("Response status code = " + Convert.ToString(resp.StatusCode));

// The response should be JSON, even if an error.
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.Load(resp.BodyStr);
json.EmitCompact = false;

Debug.WriteLine(json.Emit());

// A successful response will have a status code = 200
if (resp.StatusCode != 200) {
    Debug.WriteLine("Failed.");
}

    Debug.WriteLine("mediaId: " + json.StringOf("mediaId"));
    Debug.WriteLine("href: " + json.StringOf("_links.self.href"));
    Debug.WriteLine("status: " + json.StringOf("status"));
    Debug.WriteLine("Success.");
