Example: Http.QuickGet method

Demonstrates the QuickGet method. Go

    success := false

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

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

    // This URL is valid and can be tested...
    var zipBytes []byte

    if http.LastMethodSuccess() == false {
        fmt.Println(http.LastErrorText())
        http.DisposeHttp()
        return
    }

    if http.LastStatus() != 200 {
        fmt.Println("Response status code: ", http.LastStatus())
        fmt.Println(http.LastResponseBody())
        http.DisposeHttp()
        return
    }

    zip := chilkat.NewZip()

    // Open the zip from the bytes contained in bd.
    success = zip.OpenFromMemory(zipBytes)
    if success == false {
        fmt.Println(zip.LastErrorText())
        http.DisposeHttp()
        zip.DisposeZip()
        return

    // Get the entry for the file we want..
    entry := chilkat.NewZipEntry()
    success = zip.EntryOf("hamlet.xml",entry)
    if success == false {
        fmt.Println(zip.LastErrorText())
        http.DisposeHttp()
        zip.DisposeZip()

        zip.DisposeZip()
        entry.DisposeZipEntry()
        return

    // The XML in this case is about 274K, so let's just examine the last 20 lines...
