Gzip Compress In Memory and Base64 Encode

See more Gzip Examples

Demonstrates how to Gzip compress in-memory data and then encode the compressed data to base64. Swift

func chilkatTest() {
    var success: Bool = false

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

    let gzip = CkoGzip()!

    // This example will load a file into the fileData object.
    // Your application might load fileData from other sources..
    let fileData = CkoBinData()!
    success = fileData.loadFile(path: "qa_data/xml/hamlet.xml")
    if success != true {
        print("Failed to load file.")
        return
    }

    // In-place compress the contents of fileData
    success = gzip.compressBd(binDat: fileData)
    if success != true {
        print("\(gzip.lastErrorText!)")
        return
    }

    // Get the base64 encoded compressed data (in a single line).
    var strBase64: String? = fileData.getEncoded(encoding: "base64")
    print("\(strBase64!)")
    print("--------")

    // To get the base64 in multiple lines, as it might appear in MIME,
    // use "base64-mime".
    var strBase64MultiLine: String? = fileData.getEncoded(encoding: "base64-mime")
    print("\(strBase64MultiLine!)")
