首先引用pako.js
function gzip(str) {//加密
var binaryString = pako.gzip(str, { to: 'string' });
return btoa(binaryString);
}
function ungzip(b64Data) {//解密
var strData = atob(b64Data);
// Convert binary string to character-number array
var charData = strData.split('').map(function (x) { return x.charCodeAt(0); });
// Turn number array into byte-array
var binData = new Uint8Array(charData);
// // unzip
var data = pako.inflate(binData);
// Convert gunzipped byteArray back to ascii string:
strData = decodeUTF8(new Uint8Array(data));
return strData;
}
function decodeUTF8(arr) {//转为utf8编码字符串
var str = '';
for (var i = 0; i < arr.length; i++) {
str += String.fromCharCode(arr[i]);
}
return decodeURIComponent(escape(str));
}如：
>gzip("提示:abc123")
输出："H4sIAAAAAAAAA3vWP+H5kl1WiUnJhkbGALeI35MNAAAA"
>ungzip("H4sIAAAAAAAAA3vWP+H5kl1WiUnJhkbGALeI35MNAAAA")
输出："提示:abc123"
