當輸入包含未包含在 RFC 4648 所指定標準或 URL 安全字母表中的字元時,函式會傳回錯誤 “Msg 9803, Level 16, State 20, Line 15, Type ”Base64Decode“ 的無效數據。 如果數據具有有效的字元,但格式不正確,則函式會傳回錯誤 Msg 9803,狀態 21。 如果輸入包含兩個以上的填補字元或填補字元,後面接著...
int decode(byte[] src, byte[] dst):解码src所有字节到dst(从偏移量0开始)。如果dst不足以保存解码,或者当Base64无效的时,抛出IllegalArgumentException。否则,返回写入dst的字节数。 byte[] decode(String src):将src所有字节解码为新分配的字节数组,并返回该字节数组。调用此方法相当于调用decode(src.getBytes...
