HTTP Verb - How to use any Verb (GET, PUT, POST, DELETE, PROPFIND, etc.)

The HttpVerb property may be set to anything. Typically, it is set to the common/standard HTTP verbs such as GET, POST, PUT, DELETE, etc. It can be set to anything, including custom verbs that only have meaning to your particular server-side application.

This example demonstrates how to compose an HTTP request using the PROPFIND verb, which is something one might use with a WebDAV request.

This example composes the following HTTP request:

   PROPFIND  /container/ HTTP/1.1
   Host: www.foo.bar
   Depth: 1
   Content-Type: text/xml; charset="utf-8"
   Content-Length: xxxx

   <?xml version="1.0" encoding="utf-8" ?>
   <D:propfind xmlns:D="DAV:">
     <D:allprop/>
   </D:propfind>

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkHttpRequest req = new CkHttpRequest();

    //  The ContentType, HttpVerb, and Path properties should
    //  always be explicitly set.
    req.put_HttpVerb("PROPFIND");
    req.put_Path("/container/");
    req.put_ContentType("text/xml");
    req.put_Charset("utf-8");
    req.put_SendCharset(true);

    req.AddHeader("Depth","1");

    CkXml xml = new CkXml();
    xml.put_Tag("propfind");
    xml.AddAttribute("xmlns:D","DAV:");
    xml.NewChild2("allprop","");

    req.LoadBodyFromString(xml.getXml(),"utf-8");

    //  View the request that would be sent if HttpSReq was called:
    String requestMime = req.generateRequestText();
    Log.i(TAG, requestMime);

    //  A few important comments about the HTTP request that is generated:
    //  
    //  1) The Content-Length header is automatically generated based on the actual length of the MIME message
    //     that follows the intial (topmost) MIME header.
    //  2) The HOST header will automatically get filled in with the actual domain when HttpSReq
    //     is called.

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
