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>

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final req = CkHttpRequest();

  // The ContentType, HttpVerb, and Path properties should
  // always be explicitly set.
  req.httpVerb = 'PROPFIND';
  req.path = '/container/';
  req.contentType = 'text/xml';
  req.charset = 'utf-8';
  req.sendCharset = true;

  req.addHeader('Depth', '1');

  final xml = CkXml();
  xml.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:
  final requestMime = req.generateRequestText();
  print(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.
