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

loHttp = createobject("CkHttp")
loBd = createobject("CkBinData")

// Download the contents of a PDF file into the bd object.
llSuccess = loHttp.QuickGetBd("https://www.chilkatsoft.com/hello.pdf",loBd)
if (llSuccess = .F.) then
    // This will happen if the response status code was 400 or greater,
    // or if the request could not be sent, or if no response was received.
    // 
    // In other words, success will only be .T. if bd contains the desired content at the URL (not an error response).
    lnStatusCode = loHttp.LastStatus
    ? "Response status: " + str(lnStatusCode)

    if (lnStatusCode = 0) then
        // There was an error in communications.  
        ? loHttp.LastErrorText
    else
        // We received a response status code indicating failure.
        // Examine the response body.
        ? loHttp.LastResponseBody
    endif

    release loHttp
    release loBd
    return
endif

// Save the contents of bd to a file.
// Note: This is only for the sake of this example.
// It's better to call the Download method to download directly to a file.
llSuccess = loBd.WriteFile("qa_output/hello.pdf")
if (llSuccess = .F.) then
    ? "Failed to write output file."
else
    ? "Wrote hello.pdf"
