(Swift 3,4,5...) 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>

func chilkatTest() {
    let req = CkoHttpRequest()!

    // 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", value: "1")

    let xml = CkoXml()!
    xml.tag = "propfind"
    xml.addAttribute("xmlns:D", value: "DAV:")
    xml.newChild2("allprop", content: "")

    req.loadBody(from: xml.getXml(), charset: "utf-8")

    // View the request that would be sent if SynchronousRequest was called:
    var requestMime: String? = req.generateText()
    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 SynchronousRequest
    //    is called
