Question

我是Express和Node JS的新手，我最近学习了如何编写用于Express的API，但是最后，我遇到了一些问题，经过几次尝试我还是无法解决。我无法在localhost：8080 / users上得到响应

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：

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

原因是由于 index.js 中的app.use("/users", routes.user);设置了用户端点。如果您将/users/留在 users.js 中，则它将是 localhost：8080 / users / users / 。相同的问题可能是 / messages 。

我无法获得/ users json
