// Demonstrates how to use Basic Authentication in a REST API call for Twilio.
// Sends an SMS text message..

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

Chilkat.Rest rest = new Chilkat.Rest();

// Use Basic Authentication.
// Your Twilio Account SID is the username.
// Your Twilio Auth Token is the password.
bool success = rest.SetAuthBasic("TWILIO_ACCOUNT_SID","TWILIO_AUTH_TOKEN");

// Make the initial connection (without sending a request yet) to Twilio.
bool bTls = true;
int port = 443;
bool bAutoReconnect = true;
success = await rest.ConnectAsync("api.twilio.com",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// Provide the information for the SMS text message:
success = rest.AddQueryParam("To","+16518675309");
success = rest.AddQueryParam("From","+15005550006");
success = rest.AddQueryParam("Body","Hey Jenny! Good luck on the bar exam!");
success = rest.AddQueryParam("MediaUrl","http://farm2.static.flickr.com/1075/1404618563_3ed9a44a3a.jpg");

// Send the SMS text message.
// Your Twilio Account SID is part of the URI path:
string responseJson = await rest.FullRequestFormUrlEncodedAsync("POST","/2010-04-01/Accounts/TWILIO_ACCOUNT_SID/Messages.json");
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// When successful, the response status code will equal 201.
if (rest.ResponseStatusCode != 201) {
    // Examine the request/response to see what happened.
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));
    Debug.WriteLine("response status text = " + rest.ResponseStatusText);
    Debug.WriteLine("response header: " + rest.ResponseHeader);
    Debug.WriteLine("response body (if any): " + responseJson);
    Debug.WriteLine("---");
    Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine);
    Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

// The response is JSON.  We'll show how to get a few bits of information from it.
// A full sample JSON response is shown below..

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;
success = json.Load(responseJson);

// First show the entire JSON.
Debug.WriteLine(json.Emit());

// Now get some individual pieces of information:
Debug.WriteLine("sid: " + json.StringOf("sid"));
Debug.WriteLine("body: " + json.StringOf("body"));
Debug.WriteLine("media: " + json.StringOf("subresource_uris.media"));

Debug.WriteLine("Success.");
