Reoss上传java如何生成signature？ /**     * base64转码     *      * @param st     * @return     */    public static String base64Encode(String st) {        return new String(Base64.encodeBase64(st.getBytes()));    } /**            * 生成签名数据            *             * @param data 待加密的数据            * @param key  加密使用的key            * @throws InvalidKeyException            * @throws NoSuchAlgorithmException            */           public static String getSignature(String data,String key) throws Exception{          byte[] keyBytes=key.getBytes();             SecretKeySpec signingKey = new SecretKeySpec(keyBytes, HMAC_SHA1);                Mac mac = Mac.getInstance(HMAC_SHA1);                mac.init(signingKey);                byte[] rawHmac = mac.doFinal(data.getBytes());             StringBuilder sb=new StringBuilder();             for(byte b:rawHmac){              sb.append(byteToHexString(b));             }             return sb.toString();            }                  private static String byteToHexString(byte ib){          char[] Digit={'0','1','2','3','4','5','6','7','8','9','a','b','c','d','e','f'};          char[] ob=new char[2];          ob[0]=Digit[(ib>>>4)& 0X0f];          ob[1]=Digit[ib & 0X0F];          String s=new String(ob);          return s;                  } java生成的签明 与php生成的签明不一致。这是啥子情况泥？ ------------------------- 回3楼xgp的帖子 文档写的好蛋疼，真心看的不明白。。。。。
