Dim success As Long
success = 0

Dim http As New ChilkatHttp
success = 0

Dim sb As New ChilkatStringBuilder
success = sb.Append("{""greeting"":""Hello World""}")

' This URL echoes the contents of the request body, letting us view it.
Dim url As String
url = "https://chilkatsoft.com/echo_request_body.asp"

' Send a POST with the contents of the StringBuilder in the HTTP request body.
Dim resp As New ChilkatHttpResponse
success = http.HttpSb("POST",url,sb,"utf-8","application/json",resp)
If (success = 0) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

Debug.Print "Response Status Code: " & resp.StatusCode

' Examine the request we sent.
' The LastHeader property stores the HTTP request header of the most recent request sent,
' and in this instance, the response body mirrors the request body.
Debug.Print http.LastHeader
Debug.Print resp.BodyStr

' Output:

' POST /echo_request_body.asp HTTP/1.1
' Host: chilkatsoft.com
' Accept: */*
' Accept-Encoding: gzip
' Content-Type: application/json
' Content-Length: 26
