我正在开发SAML SP。我使用@node-saml/node-saml库。虽然我做了下面的源代码，但SAML认证不工作。你能告诉我如何修复或制作SAML SP的好参考源代码吗？
vc.ts

export const SAML = async () => {
  const express = require("express");
  const bodyParser = require("body-parser");
  const { SAML } = require("@node-saml/node-saml");

  const app = express();
  const port = 3001;

  app.use(bodyParser.urlencoded({ extended: true }));

  const spOptions = {
    issuer: "saml_XXX",
    cert: "MII...XXX",
    assert_endpoint: "https://5XXX",
    audience: "https://5XXX",
  };

  const sp = new SAML(spOptions);

  // SAMLrequest
  app.get("/login", (req: any, res: { redirect: (arg0: any) => void }) => {
    const request = sp.createLoginRequest();
    res.redirect(request);
  });

  // SAML Assertion
  app.post(
    "/assert",
    (
      req: { body: { SAMLResponse: any } },
      res: {
        status: (arg0: number) => {
          (): any;
          new (): any;
          send: { (arg0: any): any; new (): any };
        };
        redirect: (arg0: string) => any;
        send: (arg0: string) => void;
      }
    ) => {
      const response = req.body.SAMLResponse;
      sp.parseLoginResponse(
        response,
        (err: any, profile: any, loggedOut: any) => {
          if (err) {
            console.log("err:", err);
            return res.status(500).send(err);
          }

          console.log(profile);

          if (loggedOut) {
            return res.redirect("/");
          }

          res.send("Login successful!");
          return "OK!";
        }
      );
    }
  );

  return app;
};

字符串
saml-request.ts

import { error } from "console";
import { SAML } from "../../../lib/vc";

const createSamlRequest = async (req: any, res: any) => {
  const app = await SAML();
  app(req, res);
  try {
    console.log("success");
  } catch {
    console.log("failed", error);
  }
};

export default createSamlRequest;

对不起，我的英语和技术不好，谢谢你的好意。
我可能有一个spOptions内容.如果你知道，请告诉我如何在Azure Entra ID中设置SAML应用程序。（我已经阅读了下面的文档。但我无法为Assert消费者服务URL和实体ID设置正确的内容。现在我为Assert消费者服务URL设置了单个应用程序基URL，该URL可用于此源。
