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. C++

#include <CkHttp.h>
#include <CkBinData.h>
#include <CkPdf.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.

    CkHttp http;
    http.put_KeepResponseBody(true);

    CkBinData bd;

    //  Download the contents of a PDF file into the bd object.
    success = http.QuickGetBd("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();
        std::cout << "Response status: " << statusCode << "\r\n";

        if (statusCode == 0) {
            //  There was an error in communications.  
            std::cout << http.lastErrorText() << "\r\n";
        }
        else {
            //  We received a response status code indicating failure.
            //  Examine the response body.
            std::cout << http.lastResponseBody() << "\r\n";
        }

        return;
    }

    //  Load the downloaded PDF into a Chilkat PDF object.
    CkPdf pdf;
    success = pdf.LoadBd(bd);
    if (success == false) {
        std::cout << pdf.lastErrorText() << "\r\n";
        return;
    }

    //  ...

    std::cout << "Success." << "\r\n";
    }
