Duplicate curl -u user:password with Chilkat HTTP

See more HTTP Misc Examples

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

Dart

import 'package:chilkat/chilkat.dart';

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

  final http = CkHttp();
  final req = CkHttpRequest();

  // The AddHeader method corresponds to the curl "-H" argument.
  req.addHeader('Accept', 'application/json');
  req.addHeader('Accept-Language', 'en_US');

  // The curl "-d" argument specifies the HTTP request body.  In this case,
  // we're sending an application/x-www-form-urlencoded request, and therefore
  // the body contains the URL-encoded query parameters.
  req.addParam('grant_type', 'client_credentials');

  http.login = 'PAYPAL_REST_API_CLIENT_ID';
  http.password = 'PAYPAL_REST_API_SECRET';

  // Sends a POST request where the Content-Type is application/x-www-form-urlencoded
  req.httpVerb = 'POST';
  req.contentType = 'application/x-www-form-urlencoded';

  final resp = CkHttpResponse();
  try {
    http.httpReq('https://api.sandbox.paypal.com/v1/oauth2/token', req, resp);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  if (resp.statusCode != 200) {
    print('Error status code: ${resp.statusCode}');
    print(resp.bodyStr);
    return;
  }

  // The JSON response is in the resp BodyStr property
  print(resp.bodyStr);
  print('-- Success.');
