(Lianja) 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>

loReq = createobject("CkHttpRequest")

// The ContentType, HttpVerb, and Path properties should
// always be explicitly set.
loReq.HttpVerb = "PROPFIND"
loReq.Path = "/container/"
loReq.ContentType = "text/xml"
loReq.Charset = "utf-8"
loReq.SendCharset = .T.

loReq.AddHeader("Depth","1")

loXml = createobject("CkXml")
loXml.Tag = "propfind"
loXml.AddAttribute("xmlns:D","DAV:")
loXml.NewChild2("allprop","")

loReq.LoadBodyFromString(loXml.GetXml(),"utf-8")

// View the request that would be sent if SynchronousRequest was called:
lcRequestMime = loReq.GenerateRequestText()
? lcRequestMime

// 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 SynchronousRequest
//    is called
