QuickGetBd Example

The QuickGetBd method is called to send a GET request to download a binary target, such as PDF, zip, image file, etc. into a Chilkat BinData object. Unicode C++

#include <CkHttpW.h>
#include <CkBinDataW.h>
#include <CkPdfW.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkHttpW http;
    http.put_KeepResponseBody(true);

    CkBinDataW bd;

    //  Download the contents of a PDF file into the bd object.
    success = http.QuickGetBd(L"https://www.chilkatsoft.com/hello.pdf",bd);
    if (success == false) {
        //  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 true if bd contains the desired content at the URL (not an error response).
        int statusCode = http.get_LastStatus();
        wprintf(L"Response status: %d\n",statusCode);

        if (statusCode == 0) {
            //  There was an error in communications.  
            wprintf(L"%s\n",http.lastErrorText());
        }
        else {
            //  We received a response status code indicating failure.
            //  Examine the response body.
            wprintf(L"%s\n",http.lastResponseBody());
        }

        return;
    }

    //  Load the downloaded PDF into a Chilkat PDF object.
    CkPdfW pdf;
    success = pdf.LoadBd(bd);
    if (success == false) {
        wprintf(L"%s\n",pdf.lastErrorText());
