  • urlsafe_b64 RFC 4648 中描述的带有 URL 和文件名安全字母表的标准“base64url” 应用程序接口 #include "b64.h" int b64_encode(const uint8_t *in, size_t ilen, char *out, size_t *olen); int b64_decode...
  • 虽然JavaScript中可以使用原生的btoa和atob函数进行Base64的编解码。但是不支持中文字符,并且不支持url-safe的Base64编解码。当编码后的结果要是通过get请求传输时(比如跨域提交时),结果中包含有'/'字符将导致...

    byte[] b = Base64.encodeBase64URLSafe(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 =
