node.js - Express-子域看不到路由

Question

我正在使用 https://www.npmjs.com/package/express-subdomain 中的示例设置包裹。但是，当我在浏览器中尝试 api.localhost:3000 时，它会抛出错误:“Cannot GET/”

如何让 api.localhost:3000 运行？我会考虑其他解决方案，而不仅仅是使用 express-subdomain 的解决方案，只要您不必在设置中输入 FQDN。

app.js:

var subdomain = require('express-subdomain');
var express = require('express');
var app = express();

// *** Code examples below go here! ***
var router = express.Router();

//api specific routes
router.get('/', function(req, res) {
    res.send('Welcome to our API!');
});

router.get('/users', function(req, res) {
    res.json([
        { name: "Brian" }
    ]);
});

app.use(subdomain('api', router));
app.listen(3000);

package.json:

{
  "name": "auth_manager",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.16.3",
    "express-subdomain": "^1.0.5"
  }
}

Answer 1

我认为该 API 处于事件状态，位于 http://api.example.com/而不是在 api.localhost:3000 中。但是，如果您想在本地运行它们，我建议您遵循 https://www.npmjs.com/package/express-subdomain#developing-locally
