Example: Http.ResumeDownload method

Demonstrates the ResumeDownload method. Go

    success := false

    http := chilkat.NewHttp()
    http.SetKeepResponseBody(true)

    // To demonstrate resuming a download, we've created a file on the chilkatsoft.com
    // web server that contains the first 82,379 bytes of the full  279,658 bytes of the hamlet.xml file.

    // We'll first download the partial file, and pretend it was a previous incomplete attempt to download the entire file.
    localFilePath := "c:/temp/qa_output/hamlet.xml"
    success = http.Download("https://www.chilkatsoft.com/testData/hamlet_partial.xml",localFilePath)
    if success == false {
        fmt.Println(http.LastErrorText())
        http.DisposeHttp()
        return
    }

    // Download the remainder of hamlet.xml.
    success = http.ResumeDownload("https://www.chilkatsoft.com/testData/hamlet.xml",localFilePath)
    statusCode := http.LastStatus()
    if success == false {
        if statusCode == 0 {
            // Unable to either send the request or get the response.
            fmt.Println(http.LastErrorText())
        } else {
            // We got a response, but the status code was not in the 200s
            fmt.Println("Response status code: ", statusCode)
            // Examine the response body.
            fmt.Println("Response body:")
            fmt.Println(http.LastResponseBody())
        }

        fmt.Println("Download failed.")

    } else {
        fmt.Println("Download success, response status = ", statusCode)
    }

    // The hamlet.xml file should be 279,658 bytes
    fac := chilkat.NewFileAccess()
    fmt.Println("size of hamlet.xml: ", fac.FileSize(localFilePath))

    fmt.Println("Success.")

    http.DisposeHttp()
