(Visual FoxPro) Send HTTP POST using non-UTF8 such as Windows-1250Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST.
LOCAL loHttp LOCAL loReq LOCAL loJson LOCAL lnSuccess LOCAL loResp * This example requires the Chilkat API to have been previously unlocked. * See Global Unlock Sample for sample code. * For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http') loHttp = CreateObject('Chilkat.Http') * For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.HttpRequest') loReq = CreateObject('Chilkat.HttpRequest') * Load a JSON file containing strings with Polish chars. * For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject') loJson = CreateObject('Chilkat.JsonObject') lnSuccess = loJson.LoadFile("qa_data/json/has_polish_chars.json") IF (lnSuccess = 0) THEN ? loJson.LastErrorText RELEASE loHttp RELEASE loReq RELEASE loJson CANCEL 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 = 1 * 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 <> 1) THEN ? loHttp.LastErrorText RELEASE loHttp RELEASE loReq RELEASE loJson CANCEL 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&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 = 1 loReq.Charset = "windows-1250" loResp = loHttp.PostUrlEncoded("https://www.chilkatsoft.com/echoPost.cshtml",loReq) IF (loHttp.LastMethodSuccess <> 1) THEN ? loHttp.LastErrorText RELEASE loHttp RELEASE loReq RELEASE loJson CANCEL 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&tresc=3DPrzyk%B3ad * e</pre> * -------------------------------------------------- RELEASE loResp RELEASE loHttp RELEASE loReq RELEASE loJson |
