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

loHttp = createobject("CkHttp")

loReq = createobject("CkHttpRequest")

// Load a JSON file containing strings with Polish chars.
loJson = createobject("CkJsonObject")
llSuccess = loJson.LoadFile("qa_data/json/has_polish_chars.json")
if (llSuccess = .F.) then
    ? loJson.LastErrorText
    release loHttp
    release loReq
    release loJson
    return
endif

// Add the request params expected by the server-side:
loReq.AddParam("tytul",loJson.StringOf("tytul"))
loReq.AddParam("tresc",loJson.StringOf("tresc"))

// Indicate we wish to explicitly send the charset attribute in the HTTP request header.
loReq.SendCharset = .T.

// 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.

loResp = loHttp.PostUrlEncoded("https://www.chilkatsoft.com/echoPost.cshtml",loReq)
if (loHttp.LastMethodSuccess <> .T.) then
    ? loHttp.LastErrorText
    release loHttp
    release loReq
    release loJson
    return
endif

? loHttp.LastHeader
? loResp.BodyStr

// 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.

release loResp

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

loReq.SendCharset = .T.
loReq.Charset = "windows-1250"

loResp = loHttp.PostUrlEncoded("https://www.chilkatsoft.com/echoPost.cshtml",loReq)
if (loHttp.LastMethodSuccess <> .T.) then
    ? loHttp.LastErrorText
    release loHttp
    release loReq
    release loJson
    return
endif

? loHttp.LastHeader
? loResp.BodyStr

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

// --------------------------------------------------
// POST /echoPost.cshtml HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/x-www-form-urlencoded; charset=windows-1250
// Content-Length: 70
// 
// <pre>tytul=3DPrzyk%B3ad&amp;tresc=3DPrzyk%B3ad
