Create a Zip Entirely in Memory

See more Zip Examples

Demonstrates how to create a .zip from in-memory byte data and strings, and to write the .zip to an in-memory image. Go

    success := false

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

    crypt := chilkat.NewCrypt2()
    zip := chilkat.NewZip()

    success = zip.NewZip("test.zip")
    if success == false {
        fmt.Println(zip.LastErrorText())
        crypt.DisposeCrypt2()
        zip.DisposeZip()
        return
    }

    // Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
    bd := chilkat.NewBinData()
    bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
    zip.AddBd("binaryData.dat",bd)

    // Add the string "Hello World!" to the .zip
    zip.AddString("helloWorld.txt","Hello World!","utf-8")

    var zipFileInMemory []byte
    zipFileInMemory = zip.WriteToMemory()

    // We could save these files to a file, and it is a valid .zip
    fac := chilkat.NewFileAccess()
    success = fac.WriteEntireFile("test.zip",zipFileInMemory)
    if success == false {
        fmt.Println(fac.LastErrorText())
        crypt.DisposeCrypt2()
        zip.DisposeZip()
        bd.DisposeBinData()
        fac.DisposeFileAccess()
        return
    }

    fmt.Println("Zip Created!")

    crypt.DisposeCrypt2()
    zip.DisposeZip()
    bd.DisposeBinData()
    fac.DisposeFileAccess()
