创建套件URL回调URL不合法。错误代码：71009

钉钉开放平台回调给你的消息，你在收到后，需要返回给钉钉开放平台成功的消息，这个成功的消息的内容是 success 字符串，但需要使用你的套件的相关密钥【http://ddtalk.github.io/dingTalkDoc/?spm=a3140.7785475.0.0.SMUO0N#1-创建套件】进行加密，把加密得到的结果返回给钉钉开放平台。
所以还需要请你先熟悉一下加解密的相关逻辑，文档如下
http://ddtalk.github.io/dingTalkDoc/?spm=a3140.7785475.0.0.SMUO0N#加解密库和demo下载

public class Env {
    
    public static final String OAPI_HOST = "https://oapi.dingtalk.com";
    public static final String OA_BACKGROUND_URL = "";
    public static final String CORP_ID = "ding1357db912fad244f";
    
    public static final String SECRET = "";
    public static final String SSO_Secret = "";

    
    public static String suiteTicket;
    public static String authCode;
    public static String suiteToken;

    public static final String CREATE_SUITE_KEY = "suite4xxxxxxxxxxxxxxx";
    public static final String SUITE_KEY = "";
    public static final String SUITE_SECRET = "";
    public static final String TOKEN = "yzf";
    public static final String ENCODING_AES_KEY = "bhb7iwpggiwgdb6ae0x1mz00zue039lzb5xudjxjx8f";

-------------------------

都看了，逻辑已经很清楚还是没调通，文档写的就不是清楚。
有没有清晰明确的文档，别搞那么多绕来绕去的，就不想让人看明白的感觉

-------------------------

IsvReceiveServlet.java中
            /*post数据包数据中的加密数据转换成JSON对象，JSON对象的格式如下
             *  {
             *    "encrypt":"1ojQf0NSvw2WPvW7LijxS8UvISr8pdDP+rXpPbcLGOmIBNbWetRg7IP0vdhVgkVwSoZBJeQwY2zhROsJq/HJ+q6tp1qhl9L1+ccC9ZjKs1wV5bmA9NoAWQiZ+7MpzQVq+j74rJQljdVyBdI/dGOvsnBSCxCVW0ISWX0vn9lYTuuHSoaxwCGylH9xRhYHL9bRDskBc7bO0FseHQQasdfghjkl"
             *    }
             */
            JSONObject jsonEncrypt = JSONObject.parseObject(sb.toString());
            String encrypt = "？？？";

这个的应该怎么写？谢谢！
