QuickDeleteStr Example

Sends a DELETE request to a URL. The URL can potentially include params, and custom request headers can be added. 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();
  var statusCode = 0;

  // Specifiy a session log file so we can see the exact request/response
  http.sessionLogFilename = 'c:/aaworkarea/sessionLog.txt';

  // Perhaps add a custom header or two..
  http.setRequestHeader('x-exz-date', '20201012T235046Z');
  http.setRequestHeader('x-exz-id', '1234');

  // Send a DELETE request to https://www.example.com/someting?param1=123&param2=abc
  final url = 'https://www.example.com/someting?param1=123&param2=abc';
  final String reponseBodyStr;
  try {
    reponseBodyStr = http.quickDeleteStr(url);
  } 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.
    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;
  }

  // The DELETE request that is sent looks like this.
  // The Accept and Accept-Encoding headers are automatically added by default.

  // 	DELETE /someting?param1=123&param2=abc HTTP/1.1
  // 	Host: www.example.com
  // 	Accept: */*
  // 	Accept-Encoding: gzip
  // 	x-exz-date: 20201012T235046Z
  // 	x-exz-id: 1234

  // Get the response status
  statusCode = http.lastStatus;
  print('Response status: $statusCode');

  // Show the response body
  print(reponseBodyStr);
