QuickGetBd Example

The QuickGetBd method is called to send a GET request to download a binary target, such as PDF, zip, image file, etc. into a Chilkat BinData object. 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.

  final http = CkHttp();
  http.keepResponseBody = true;

  final bd = CkBinData();

  // Download the contents of a PDF file into the bd object.
  try {
    http.quickGetBd('https://www.chilkatsoft.com/hello.pdf', bd);
  } on ChilkatException catch (e) {
    // This will happen if the response status code was 400 or greater,
    // or if the request could not be sent, or if no response was received.
    // 
    // In other words, success will only be true if bd contains the desired content at the URL (not an error response).
    final statusCode = http.lastStatus;
    print('Response status: $statusCode');

    if (statusCode == 0) {
      // There was an error in communications.  
      print(e.lastErrorText);
    } else {
      // We received a response status code indicating failure.
      // Examine the response body.
      print(http.lastResponseBody);
    }

    return;
  }

  // Load the downloaded PDF into a Chilkat PDF object.
  final pdf = CkPdf();
  try {
    pdf.loadBd(bd);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // ...

  print('Success.');
