Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST.

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

$oHttp = ObjCreate("Chilkat.Http")

$oReq = ObjCreate("Chilkat.HttpRequest")

; Load a JSON file containing strings with Polish chars.
$oJson = ObjCreate("Chilkat.JsonObject")
Local $bSuccess = $oJson.LoadFile("qa_data/json/has_polish_chars.json")
If ($bSuccess = False) Then
    ConsoleWrite($oJson.LastErrorText & @CRLF)
    Exit
EndIf

; Add the request params expected by the server-side:
$oReq.AddParam "tytul",$oJson.StringOf("tytul")
$oReq.AddParam "tresc",$oJson.StringOf("tresc")

; Indicate we wish to explicitly send the charset attribute in the HTTP request header.
$oReq.SendCharset = True

; Send the POST
; You can send the POST to the URL below.  It will respond with the request body in quoted-printable format.
; Using quoted-printable, we can easily see the binary bytes for the accented chars.
Local $oResp
$oResp = $oHttp.PostUrlEncoded("https://www.chilkatsoft.com/echoPost.cshtml",$oReq)
If ($oHttp.LastMethodSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

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

; Sample output:

; --------------------------------------------------
; POST /echoPost.cshtml HTTP/1.1
; Host: www.chilkatsoft.com
; Content-Type: application/x-www-form-urlencoded; charset=utf-8
; Content-Length: 79
; 
; <pre>tytul=3DPrzyk%C5%82ad&amp;tresc=3DPrzyk%C5%82ad
; %82oszenie</pre>
; --------------------------------------------------

; We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

; -----------------------
; However.. we can change the charset used for the HTTP request by specifying the request object's charset.

$oReq.SendCharset = True
$oReq.Charset = "windows-1250"

$oResp = $oHttp.PostUrlEncoded("https://www.chilkatsoft.com/echoPost.cshtml",$oReq)
If ($oHttp.LastMethodSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

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

; Sample output...
; You can see how the bytes used for the Polish chars are now 1-byte per char (i.e. using Windows-1250)
