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>

Lua

local chilkat = require("chilkat")

local req = chilkat.HttpRequest.new()

-- The ContentType, HttpVerb, and Path properties should
-- always be explicitly set.
req.http_verb = "PROPFIND"
req.path = "/container/"
req.content_type = "text/xml"
req.charset = "utf-8"
req.send_charset = true

req:add_header("Depth", "1")

local xml = chilkat.Xml.new()
xml.tag = "propfind"
xml:add_attribute("xmlns:D", "DAV:")
xml:new_child2("allprop", "")

req:load_body_from_string(xml:get_xml(), "utf-8")

-- View the request that would be sent if HttpSReq was called:
local requestMime = req:generate_request_text()
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.
