Dim success As Boolean = False

Dim http As New Chilkat.Http
success = False

' This example will send an HTTP POST with the body of the HTTP request containing JSON.

' Create the following JSON: { "name": "Harry", "state": "FL" }

Dim json As New Chilkat.JsonObject
json.UpdateString("name","Harry")
json.UpdateString("state","FL")

' Specify the details of the request
Dim req As New Chilkat.HttpRequest

req.HttpVerb = "POST"
req.ContentType = "application/json"
req.LoadBodyFromString(json.Emit(),"utf-8")

' Send the charset attribute in the HTTP request header.
req.SendCharset = True
req.Charset = "utf-8"

' Send the POST
' You can send the POST to the URL below.  
' The response will contain the raw body of the request that was sent.
' (i.e. everything except the HTTP request header).

Dim resp As New Chilkat.HttpResponse
success = http.HttpReq("https://www.chilkatsoft.com/echo_request_body.asp",req,resp)
If (success = False) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' Examine the HTTP request header we sent:
Debug.WriteLine(http.LastHeader)

' The response body contains the raw content of the HTTP request body we sent.
Debug.WriteLine(resp.BodyStr)

' Sample output:

' POST /echo_request_body.asp HTTP/1.1
' Host: www.chilkatsoft.com
' Content-Type: application/json; charset=utf-8
' Content-Length: 29
' 
' 
' {"name":"Harry","state":"FL"}
