Decode Base64 string

原文 2019-05-29 12:31:43 7 1 javascript/ base64/ decode/ encode

I am currently working on a custom SAPUI5 app. I would like to make a service call, which expects the Guid in a different format than it is currently available.

An example:

Available (base64): QvLAUUzUCZbhAAAAjSS2iA==
As it should be (hexadecimal): 42F2C0514CD40996E10000008D24B688

I have not found an online decoder, which could produce the desired result, however, I was able to encode the guid 42F2C0514CD40996E10000008D24B to QvLAUUzUCZbhAAAAjss2iA== with the SAP ABAP standard function module HTTP_BASE64_ENCODE . With the usual online encoders, however, I got a different result.

How can I decode the encoded guid with JavaScript so that it has the desired format?

The string is in hexadecimal format you will have to convert it.

First you convert the string to binary (atob > charCodeAt) and then using the toString(16) you get the hex.
