Ungzip Base64 String

Suppose you have a gzip in base64 representation that contains a text file, such as XML. This example shows how to decompress and access the string.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

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

var gzip = new CkGzip();

var gzipBase64 = "H4sIAAAAAAAE ... X6aZjXO3EwAA";

var bd = new CkBinData();
success = bd.AppendEncoded(gzipBase64,"base64");

success = gzip.UncompressBd(bd);
if (success !== true) {
    console.log(gzip.LastErrorText);
    return;
}

var strXml = bd.GetString("utf-8");
console.log("XML:");
console.log(strXml);
