Dart Requires Chilkat v11.0.0+

HTTP POST JSON (application/json)

See more HTTP Examples

Demonstrates how to send a JSON POST using the application/json content-type. 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 req = CkHttpRequest();
  final http = CkHttp();

  // If any custom headers need to be included with the POST, add them
  // by calling SetRequestHeader

  // Note: An application should never explicitly set the Content-Length header.
  // The Content-Length is automatically computed and added by Chilkat.

  // Here are some examples of custom headers.  

  // Perhaps your particular app needs some sort of custom-computed Authorization header...
  http.setRequestHeader('Authorization', 'my-custom-computed-auth-value');

  // Another custom header for some hypothetical app:
  http.setRequestHeader('X-Pass-Timestamp', 'my-custom-computed-timestamp-value');

  // The following "Accept" header may be set, but it really isn't necessary:
  http.setRequestHeader('Accept', 'application/json');

  final jsonText = '{ some JSON text ... }';

  // To use SSL/TLS, simply use "https://" in the URL.

  final resp = CkHttpResponse();
  try {
    http.httpStr('POST', 'http://www.someserver.com/someJsonEndpoint', jsonText, 'utf-8', 'application/json', resp);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Display the JSON response.
  print(resp.bodyStr);
