Bad base-64 error
问题 I'm getting a "java.lang.IllegalArgumentException: bad base-64" on the following code: byte[] msgBytes = Base64.decode(msgStr, Base64.NO_WRAP); msgString is a String, and right before this line, I check the value of msgStr and it is "fl-ILw==". Is there anything wrong? Thanks. 回答1: According to RFC 4648(http://www.rfc-editor.org/rfc/rfc4648.txt) '-' character is not a valid Base64 character but on the other hand is valid for "URL and Filename safe Base 64 Alphabet". So you could use Base64
