; This URL echoes the contents of the request body, letting us view it.
Local $sUrl = "https://chilkatsoft.com/echo_request_body.asp"

; Send a POST with the contents of the StringBuilder in the HTTP request body.
$oResp = ObjCreate("Chilkat.HttpResponse")
$bSuccess = $oHttp.HttpSb("POST",$sUrl,$oSb,"utf-8","application/json",$oResp)
If ($bSuccess = False) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite("Response Status Code: " & $oResp.StatusCode & @CRLF)

; 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.
ConsoleWrite($oHttp.LastHeader & @CRLF)
ConsoleWrite($oResp.BodyStr & @CRLF)

; Output:

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