    byte[] b = Base64.encodeBase64URLSafe(data.getBytes(ENCODING));

    byte[] b = Base64.encodeBase64(data.getBytes(ENCODING));

    区别在于encodeBase64会对字符串3位一组自动补全,因而最后可能会出现 == 或者 =

    而encodeBase64URLSafe则是按照字符串实际位数进行加密,最后若为1位,则不补全,不会出现 == 或者 =

  • 总所周知的,BASE64是通用算法,不同语言都应该有基础框架支持这种编码方式,而Java写法里面,apche搞了个包org.apache.commons.codec.binary,这个包里面的Base64.encodeBase64URLSafe方法就比较奇葩,通过命名...

    其实咱们都知道,开发很简单,数据对接也不难,难的是标准的兼容。比如咱们是C#写的代码,对方是Java写的或者是PHP写的代码,这个时候通用的倒是无所谓,但是部分写法是某种语言专用的,因此可能兼容起来就非常的困难。比如对方给了个标准RSA加密,pkcs8,那么我们就得去深入研究了,今天我们讨论的不是RSA的问题,而是BASE64加密的问题。

    总所周知的,BASE64是通用算法,不同语言都应该有基础框架支持这种编码方式,而Java写法里面,apche搞了个包org.apache.commons.codec.binary,这个包里面的Base64.encodeBase64URLSafe方法就比较奇葩,通过命名可以知道是安全的URL,通过名称我们猜想应该是把Base64里面的等号(=)做了处理。这里就不细说了,咱们把C#里面的写法共享出来,分享给大家。

    C#咱们新增一个ConvertHelper类处理:

    public classConvertHelper

    {///

    ///将Java安全的base64字符串转换为byte数组///

    ///

    ///

    ///

    public static byte[] FromBase64StringURLSafe(stringjavaURLSafeString)

    {

    javaURLSafeString= javaURLSafeString.Replace("-", "+").Replace("_", "/");var base64 =Encoding.ASCII.GetBytes(javaURLSafeString);var padding = base64.Length * 3 % 4;//(base64.Length*6 % 8)/2

    if (padding != 0)

    {

    javaURLSafeString= javaURLSafeString.PadRight(javaURLSafeString.Length + padding, ‘=‘);

    }returnConvert.FromBase64String(javaURLSafeString);

    }///

    ///将byte数组转换为java安全的base64字符串///

    ///

    ///

    ///

    public static string ToBase64StringURLSafe(byte[] bytes)

    {string base64String =Convert.ToBase64String(bytes);return base64String.Replace("+", "-")

    .Replace("/", "_")

    .Replace("=", "");

    }

    }

    通过代码我们可以明显看出,实际上就是对+、/、=进行了特殊处理。
