Dart Requires Chilkat v11.0.0+

HTTP GET with Non-USASCII Query Params

See more HTTP Examples

This example illustrates how query parameters in a URL are typically encoded and transmitted. Dart

import 'package:chilkat/chilkat.dart';

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

  // First, let's load the string "Grünhöfer GmbH" from a file.  (This is a fictitious company name.)
  // The file uses the utf-8 charset encoding.
  final sbCompanyName = CkStringBuilder();
  sbCompanyName.loadFile('qa_data/txt/companyName.txt', 'utf-8');
  // Assuming success for this example...

  // We'll send an HTTP GET request to https://chilkatsoft.com/example?company_name={company name}

  // When sending an HTTP GET request with query parameters that contain accented characters 
  // (e.g., umlauts: ä, ö, ü), they must be percent-encoded (URL encoded) to ensure proper transmission and 
  // interpretation by the server.  This is based on their UTF-8 byte values.
  final sbUrl = CkStringBuilder();
  sbUrl.append('https://chilkatsoft.com/example?company_name=');
  sbUrl.append(sbCompanyName.getEncoded('url', 'utf-8'));

  final http = CkHttp();

  // Send the following HTTP GET request:

  // GET /example?company_name=Gr%C3%BCnh%C3%B6fer%20GmbH HTTP/1.1
  // Host: chilkatsoft.com
  // Accept: */*
  // Accept-Encoding: gzip

  final sbResponse = CkStringBuilder();
  try {
    http.quickGetSb(sbUrl.getAsString(), sbResponse);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('response status code: ${http.lastStatus}');
  print(sbResponse.getAsString());
