String based data encoding: Base64 vs Base64url

阅读更多关于 String based data encoding: Base64 vs Base64url

What is the difference between Base64 and Base64url that I see in things like JSON web tokens? Both Base64 and Base64url are ways to encode binary data in string form. You can read about the theory of base64 here . The problem with Base64 is that it contains the characters + , / , and = , which have a reserved meaning in some filesystem names and URLs. So base64url solves this by replacing + with - and / with _ . The trailing padding character = can be eliminated when not needed, but in a URL it would instead most likely be % URL encoded. Then the encoded data can be included in a URL without
