// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code

loo_Req = create oleobject
li_rc = loo_Req.ConnectToNewObject("Chilkat_9_5_0.HttpRequest")
if li_rc < 0 then
    destroy loo_Req
    MessageBox("Error","Connecting to COM object failed")

// This example duplicates the HTTP POST shown at
// http://json.org/JSONRequest.html

// Specifically, the request to be sent looks like this:

// POST /request HTTP/1.1
// Accept: application/jsonrequest
// Content-Encoding: identity
// Content-Length: 72
// Content-Type: application/jsonrequest
// Host: json.penzance.org
// 
// {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

// First, remove default header fields that would be automatically
// sent.  (These headers are harmless, and shouldn't need to 
// be suppressed, but just in case...)
loo_Http.AcceptCharset = ""
loo_Http.UserAgent = ""
loo_Http.AcceptLanguage = ""
// Suppress the Accept-Encoding header by disallowing 
// a gzip response:
loo_Http.AllowGzip = 0

// If a Cookie needs to be added, it may be added by calling
// AddQuickHeader:
li_Success = loo_Http.AddQuickHeader("Cookie","JSESSIONID=1234")

ls_JsonText = "{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}"

// To use SSL/TLS, simply use "https://" in the URL.

// IMPORTANT: Make sure to change the URL, JSON text,
// and other data items to your own values.  The URL used
// in this example will not actually work.

loo_Resp = loo_Http.PostJson("http://json.penzance.org/request",ls_JsonText)
if loo_Http.LastMethodSuccess <> 1 then
    Write-Debug loo_Http.LastErrorText
else
    // Display the JSON response.
    Write-Debug loo_Resp.BodyStr
    destroy loo_Resp
end if
