HTTPS GET URL with URL Encoded Query Params

See more HTTP Examples

Creates a URL with URL encoded query params, and sends an HTTPS GET to the URL. Dart

import 'package:chilkat/chilkat.dart';

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

  // Create a URL with URL-encoded query params.
  final sbUrl = CkStringBuilder();
  sbUrl.append('https://www.example.com/something?');

  // If we know a query param value does not have any special chars requiring URL encoding,
  // just add it.  In this case, there is no need to URL encode "123" because "123" url encoded is still just "123".
  sbUrl.append('abc=123&xyz=');

  final sbValue = CkStringBuilder();
  sbValue.append('this is a test');

  sbUrl.append('msg=');
  sbUrl.append(sbValue.getEncoded('url', 'utf-8'));

  // sbUrl contains:  https://www.example.com/something?abc=123&xyz=msg=this%20is%20a%20test
  print(sbUrl.getAsString());

  // Send the GET request and get the response body, which is assumed to be text of some sort (HTML, XML, JSON, etc.)
  // (Chilkat automatically decompresses gzipped responses)
  final http = CkHttp();
  final String responseBody;
  try {
    responseBody = http.quickGetStr(sbUrl.getAsString());
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Response Body:');
  print(responseBody);
