Asynchronous HTTPS Upload (TLS)

See more Upload Examples

Demonstrates how to do an HTTPS (TLS) upload asynchronously in a background thread.

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload

C++

#include <CkUpload.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkUpload upload;

    // Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
    // that will process the HTTP Upload.
    upload.put_Hostname("www.mywebserver.com");
    upload.put_Path("/receiveUpload.aspx");

    // Add one or more files to be uploaded.
    upload.AddFileReference("file1","dude.gif");
    upload.AddFileReference("file2","pigs.xml");
    upload.AddFileReference("file3","sample.doc");

    // To upload using SSL/TLS (https), set the Ssl property = true
    upload.put_Ssl(true);

    // Begin the HTTP upload in a background thread:
    success = upload.BeginUpload();
    if (success != true) {
        std::cout << upload.lastErrorText() << "\r\n";
    }
    else {
        std::cout << "Upload started.." << "\r\n";
    }

    // Wait for the upload to finish.
    // Print the progress as we wait...
    while ((upload.get_UploadInProgress() == true)) {
        // We can abort the upload at any point by calling:
        // upload.AbortUpload();

        // Display the percentage complete and the number of bytes uploaded so far..
        // The total upload size will become set after the upload begins:
        std::cout << upload.get_PercentUploaded() << "% " << upload.get_NumBytesSent() << "/" << upload.get_TotalUploadSize() << "\r\n";

        // Sleep 2/10ths of a second.
        upload.SleepMs(200);

    }

    // Did the upload succeed?
    if (upload.get_UploadSuccess() == true) {
        std::cout << "Files uploaded!" << "\r\n";
    }
    else {
        std::cout << upload.lastErrorText() << "\r\n";
    }
    }
