Go

Send HTTP POST using non-UTF8 such as Windows-1250

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

    success := false

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

    http := chilkat.NewHttp()

    req := chilkat.NewHttpRequest()

    // Load a JSON file containing strings with Polish chars.
    json := chilkat.NewJsonObject()
    success = json.LoadFile("qa_data/json/has_polish_chars.json")
    if success == false {
        fmt.Println(json.LastErrorText())
        http.DisposeHttp()
        req.DisposeHttpRequest()
        json.DisposeJsonObject()
        return
    }

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

    // Indicate we wish to explicitly send the charset attribute in the HTTP request header.
    req.SetSendCharset(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.

    req.SetHttpVerb("POST")
    req.SetContentType("application/x-www-form-urlencoded")

    resp := chilkat.NewHttpResponse()
    success = http.HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",req,resp)
    if success == false {
        fmt.Println(http.LastErrorText())
        http.DisposeHttp()
        req.DisposeHttpRequest()
        json.DisposeJsonObject()
        resp.DisposeHttpResponse()
        return
    }

    fmt.Println(http.LastHeader())
    fmt.Println(resp.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.

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

    req.SetSendCharset(true)
    req.SetCharset("windows-1250")
    req.SetHttpVerb("POST")
    req.SetContentType("application/x-www-form-urlencoded")

    success = http.HttpReq("https://www.chilkatsoft.com/echoPost.cshtml",req,resp)

        resp.DisposeHttpResponse()
        return
    }

    fmt.Println(http.LastHeader())
    fmt.Println(resp.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
