' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim req As New Chilkat.HttpRequest
Dim http As New Chilkat.Http

' The PUT request to be sent will look like this:

' PUT /request HTTP/1.1
' Content-Type: application/jsonrequest
' Cookie: JSESSIONID=1234
' Content-Encoding: identity
' Host: json.penzance.org
' Accept: application/jsonrequest
' Accept-Encoding:
' Content-Length: 72
' 
' {"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...)
http.AcceptCharset = ""
http.UserAgent = ""
http.AcceptLanguage = ""

' Suppress the Accept-Encoding header by disallowing 
' a gzip response:
http.AllowGzip = False

' If a Cookie needs to be added, it may be added by calling
' AddQuickHeader:
Dim success As Boolean = http.AddQuickHeader("Cookie","JSESSIONID=1234")

' Add the Content-Encoding: identity header.
success = http.AddQuickHeader("Content-Encoding","identity")

' Modify the default "Accept" header:
http.Accept = "application/jsonrequest"


Dim jsonText As String = "{""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.

Dim responseBody As String = http.PutText("http://json.penzance.org/request",jsonText,"utf-8","application/jsonrequest",False,False)
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
Else
    ' Display the JSON response.
    Debug.WriteLine(responseBody)

End If
