Asynchronous HTTP Upload

See more Upload Examples

Demonstrates how to do an HTTP 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

Go

    success := false

    upload := chilkat.NewUpload()

    // Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
    // that will process the HTTP Upload.
    upload.SetHostname("www.mywebserver.com")
    upload.SetPath("/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")

    // Begin the HTTP upload in a background thread:
    success = upload.BeginUpload()
    if success != true {
        fmt.Println(upload.LastErrorText())
    } else {
        fmt.Println("Upload started...")
    }

    // Wait for the upload to finish.
    // Print the progress as we wait...
    for (upload.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:
        fmt.Println(upload.PercentUploaded(), "% ", upload.NumBytesSent(), "/", upload.TotalUploadSize())

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

    }

    // Did the upload succeed?
    if upload.UploadSuccess() == true {
        fmt.Println("Files uploaded!")
    } else {
        fmt.Println(upload.LastErrorText())
    }


    upload.DisposeUpload()
