Node.js 我无法获取/json用户

我是express和node js的新手，最近我学习了如何为express编写API，但最后，我遇到了一些问题，经过几次尝试，我都没有解决。我无法在localhost:8080/users上获得响应

src/routes/users.js

const { Router } = require("express");
const router = Router();

const getUsers = (req, res) =>
  res.send(Object.values(req.context.models.users));
const getUser = (req, res) =>
  res.send(req.context.models.users[req.params.userId]);

router.get("/users/", getUsers);
router.get("/users/:userId", getUser);

module.exports = router;

src/routes/index.js

const user = require("./user");
const message = require("./message");

module.exports = {
  user,
  message
};

src/index.js

const express = require("express");
const app = express();

// Custom Modules
const routes = require("./routes");
const models = require("./models");

// Application-Level Middleware Starts
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

app.use((req, res, next) => {
  req.context = {
    models,
    me: models.users[1]
  };
  console.log(req.context.models.users);
  next();
});

// Used Routes

app.use("/users", routes.user);
app.use("/messages", routes.message);

// App Listning to HTTPS Module
app.listen(process.env.PORT);

您需要在users.js中修复端点：

原因是

app.use（“/users”，routes.user）/users/

留在users.js中，它将是localhost:8080/users/users/。/messages也可能存在同样的问题。

运行index.js时，终端中是否显示任何错误？

router.get("/", getUsers);
router.get("/:userId", getUser);
