HTTP GET with Non-USASCII Query Params

See more HTTP Examples

This example illustrates how query parameters in a URL are typically encoded and transmitted. Go

    success := false

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

    // First, let's load the string "Grünhöfer GmbH" from a file.  (This is a fictitious company name.)
    // The file uses the utf-8 charset encoding.
    sbCompanyName := chilkat.NewStringBuilder()
    success = sbCompanyName.LoadFile("qa_data/txt/companyName.txt","utf-8")
    // Assuming success for this example...

    // We'll send an HTTP GET request to https://chilkatsoft.com/example?company_name={company name}

    // When sending an HTTP GET request with query parameters that contain accented characters 
    // (e.g., umlauts: ä, ö, ü), they must be percent-encoded (URL encoded) to ensure proper transmission and 
    // interpretation by the server.  This is based on their UTF-8 byte values.
    sbUrl := chilkat.NewStringBuilder()
    sbUrl.Append("https://chilkatsoft.com/example?company_name=")
    sbUrl.Append(*sbCompanyName.GetEncoded("url","utf-8"))

    http := chilkat.NewHttp()

    // Send the following HTTP GET request:

    // GET /example?company_name=Gr%C3%BCnh%C3%B6fer%20GmbH HTTP/1.1
    // Host: chilkatsoft.com
    // Accept: */*
    // Accept-Encoding: gzip

    sbResponse := chilkat.NewStringBuilder()
    success = http.QuickGetSb(*sbUrl.GetAsString(),sbResponse)
    if success == false {
        fmt.Println(http.LastErrorText())
        sbCompanyName.DisposeStringBuilder()
        sbUrl.DisposeStringBuilder()
        http.DisposeHttp()
        sbResponse.DisposeStringBuilder()
        return
    }

    fmt.Println("response status code: ", http.LastStatus())
    fmt.Println(*sbResponse.GetAsString())

    sbCompanyName.DisposeStringBuilder()
    sbUrl.DisposeStringBuilder()
    http.DisposeHttp()
    sbResponse.DisposeStringBuilder()
