输入字节68处的base64数据非法

Question

I am getting: error: illegal base64 data at input byte 68 When passing in base64_edcode string into base64.StdEncoding.DecodeString(str):

the string is:

TbHl6ijhdKwXklzOkw5+/r5Yac0kED8Iyp/7suphsFLHSJAUGM8vZHeroTeJ9eF4PePO5A

but put the string into php base64_decoed is ok result is 0000000000bd583f958a7018c9[11,"string",8641231,1111]

Why?

Answer 1

Because it's not a valid Base 64 string. It's missing the end padding. With proper padding:

TbHl6ijhdKwXklzOkw5+/r5Yac0kED8Iyp/7suphsFLHSJAUGM8vZHeroTeJ9eF4PePO5A==

it works, or you can tell the decoder not to look for padding:

    out, err := base64.StdEncoding.WithPadding(base64.NoPadding).DecodeString(str)
