Example: Http.SetOAuthRsaKey method

Demonstrates the SetOAuthRsaKey method. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final pfx = CkPfx();
  try {
    pfx.loadPfxFile('qa_data/pfx/MCD_Sandbox_chilkat_iccp_API_Keys/chilkat_iccp-sandbox.p12', 'keystorepassword');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final privKey = CkPrivateKey();
  try {
    pfx.privateKeyAt(0, privKey);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final http = CkHttp();

  // Use OAuth1.0a authentication.
  http.oAuth1 = true;

  // Use your own consumer key (this is not a valid consumer key)
  http.oAuthConsumerKey = '123abc';

  http.oAuthSigMethod = 'RSA-SHA256';

  try {
    http.setOAuthRsaKey(privKey);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Tell Chilkat to automatically calculate and add the oauth_body_hash field when sending the request.
  http.oAuthBodyHash = true;

  // Send this request to an endpoint at chilkatsoft.com.  The purpose of this example is to show
  // how the OAuth1.0a Authorization header is computed and sent by Chilkat.
  // The chilkatsoft.com site itself doesn't do OAuth1.  It's just ignoring the Authorization header.
  final resp = CkHttpResponse();
  try {
    http.httpStr('POST', 'https://chilkatsoft.com/echo_request_body.asp', '<notUsed>123</notUsed>', 'utf-8', 'application/xml', resp);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Examine the request header we just sent..
  print(http.lastHeader);

  // Sample output:

  // POST /echo_request_body.asp HTTP/1.1

  // Accept: */*
