HTTP Response Inspection

See more HTTP Examples

Demonstrates how to inspect the HTTP response, including the status code, status text, and response headers, for Chilkat methods that don't use an HttpResponse object. 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[])
  {
    CkHttp http = new CkHttp();

    //  Returns the contents of the response body.
    String jsonText = http.quickGetStr("https://chilkatsoft.com/helloWorld.json");

    //  Examine the response status code.
    System.out.println("response status code: " + http.get_LastStatus());

    //  Examine the response status text
    System.out.println("response status text: " + http.lastStatusText());

    //  Examine the full response header.
    System.out.println("response header:");
    System.out.println(http.lastResponseHeader());
    System.out.println("----");

    //  Examine the response content-type
    System.out.println("LastContentType = " + http.lastContentType());

    //  Examine the response last-mod date
    System.out.println("LastModDate = " + http.lastModDate());

    //  Load the response header into a Chilkat MIME object to access its fields individually.
    CkMime mime = new CkMime();
    mime.LoadMime(http.lastResponseHeader());

    int numHeaders = mime.get_NumHeaderFields();
    int i = 0;
    System.out.println("---- MIME Headers ----");
    while (i < numHeaders) {
        System.out.println("name:  " + mime.getHeaderFieldName(i));
        System.out.println("value: " + mime.getHeaderFieldValue(i));
        i = i+1;
        }

    System.out.println("----");

    //  Get a header field value by name:
    System.out.println("ETag: " + mime.getHeaderField("ETag"));

    //  Output:

    //  response status code: 200
