During the script execution, util.base64Decoding is used for base64 decoding. 
base64Decoding(input: string, encoding?: "std" | "rawstd" | "url" | "rawurl", mode?: "b"): string | ArrayBuffer
Background
The different base64 encoding methods are as follows:
StdEncoding is the standard Base64 encoding as defined in RFC 4648.
RawStdEncoding is the standard raw, unpadded base64 encoding as defined in Section 3.2 of RFC 4648; it is the same as StdEncoding but omits the padding characters.
URLEncoding is the alternate base64 encoding defined in RFC 4648, typically used for URLs and file names.
RawURLEncoding is the unpadded alternate base64 encoding defined in RFC 4648, typically used for URLs and file names; it is the same as URLEncoding but omits the padding characters.
Parameters
Parameter
Type
Description
input
string
The string to be decoded.
encoding (optional)
string
Optional; represents the different encoding methods mentioned above; optional values include "std", "rawstd", "url", and "rawurl". If not set, defaults to "std".
mode (optional)
string
Optional; if not set, the result is of type string. If set to "b", the result is of type ArrayBuffer.
Return
Type
Description
string or ArrayBuffer.
The result obtained through base64 decoding.
Usage Examples
Use the base64Decoding method without specifying encoding:
import util from 'pts/util';
﻿
export default function () {
  // Hello, world
  console.log(util.base64Decoding('SGVsbG8sIHdvcmxk')); 
}
Use the base64Decoding method with a specified encoding:
import util from 'pts/util';
﻿
export default function () {
  // http://www.example.com
  console.log(util.base64Decoding('aHR0cDovL3d3dy5leGFtcGxlLmNvbQ==', 'url')); 
}
Use the base64Decoding method with a specified mode:
import util from 'pts/util';
﻿
export default function () {
  // [object ArrayBuffer]
  console.log(util.base64Decoding('SGVsbG8sIHdvcmxk', 'std', 'b')); 
}
﻿
