Demonstrates how to send a JSON POST using the application/json content-type. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkHttpRequest req = new CkHttpRequest();
    CkHttp http = new 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");

    String jsonText = "{ some JSON text ... }";

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

    CkHttpResponse resp = new CkHttpResponse();
    success = http.HttpStr("POST","http://www.someserver.com/someJsonEndpoint",jsonText,"utf-8","application/json",resp);
    if (success == false) {
        System.out.println(http.lastErrorText());
        return;
        }

    // Display the JSON response.
    System.out.println(resp.bodyStr());
