文档中（保密）提供了php的加解密方法，这里就不重复描述，java方法类型提供如下
小程序前端：
<button open-type="getRealnameAuthInfo" bindgetrealnameauthinfo="queryuserInfo" style='font-size: 40rpx;border-radius:0rpx; background-color: #005bac; line-height: 90rpx;color:white;' category-id="{{[99, 6]}}">获取实名</button>前端需要注意的是行业目录坐标category-id,具体不重复。
后端加密解密java代码
/** * 私钥加密 */public static String sign(String request, String privateKey) throws Exception {byte[] data = request.getBytes("UTF-8");byte[] keyBytes = Base64Util.decode(privateKey);PKCS8EncodedKeySpec pkcs8KeySpec = new PKCS8EncodedKeySpec(keyBytes);KeyFactory keyFactory = KeyFactory.getInstance("RSA");PrivateKey privateK = keyFactory.generatePrivate(pkcs8KeySpec);Signature signature = Signature.getInstance("SHA256WithRSA");signature.initSign(privateK);signature.update(data);return Base64Util.encode(signature.sign());}// 私钥解密public static String decryptByPrivateKey(String content, String Key) throws Exception {// 将base64编码后的私钥字符串转成PrivateKey实例byte[] keyBytes = Base64.getDecoder().decode(Key.getBytes());PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(keyBytes);KeyFactory keyFactory = KeyFactory.getInstance("RSA");PrivateKey privateKey = keyFactory.generatePrivate(keySpec);// 获取私钥Cipher cipher = Cipher.getInstance("RSA");cipher.init(Cipher.DECRYPT_MODE, privateKey);byte[] cipherText = Base64.getDecoder().decode(content);byte[] decryptText = cipher.doFinal(cipherText);return new String(decryptText, "gbk");}由于接口为高级接口，不能公开，提供java后端加密解密方法，仅供参考

有人私底下问我是不是少个类，我现在给补上。这个类很简单的。
