Nodejs，koa-router，koa-views（twig）返回“Not found”

所以我开始了我的新项目，我的一个朋友召集我抛弃PHP并尝试使用rethinkDB尝试Nodejs .

我安装了一切，没有路线，它的工作原理 . 但是一旦我添加了路由，我得到了： Not Found ，控制台上没有错误 .

Packages ：

"dependencies": {
    "keygrip": "^1.0.1",
    "koa": "^2.3.0",
    "koa-controller": "^1.1.0", //Not used - discontinued ?
    "koa-response-time": "^2.0.0",
    "koa-router": "^7.2.1",
    "koa-views": "^6.0.2",
    "rethinkdbdash": "^2.3.29",
    "socketio": "^1.0.0",
    "twig": "^1.10.5"
  }

server.js ：

var Koa = require('koa'),
      Router = require('koa-router'),
      keygrip = require("keygrip"),
      r = require('rethinkdbdash')(),
      views = require('koa-views'),
      Twig = require('twig'),
      twig = Twig.twig,
      app = new Koa(), // Init Koa
      router = new Router(); //Init router

//configure VIEWS
app.use(views(__dirname + '/views/', { extension: 'twig', map: {twig: 'twig' }}))

//Initialize controllers
var ot = require(__dirname+'/controllers/ot.js');

//app.keys = ['im a newer secret', 'i like turtle'];

router
  .get('/', async function (ctx, next) {

      async (ctx, next) => {
        /*ctx.state = {
          session: this.session,
          title: 'app'
        };*/
        ctx.render('index', {
            message: 'Hello world! <3'
        });
      };
  });

app
    .use(router.routes())
    .use(router.allowedMethods());
app.listen(3000);
console.log('server listen on http://localhost:3000');

ot.js ：

var ot = function() {};

ot.prototype = {
    'index' : async function(ctx, next) {

        ctx.state = {
            session: this.session,
            title: 'app'
        };

        await ctx.render('index', {
            message: 'Hello world! <3'
        });

        console.log(ctx);

    }
};

module.exports = new ot();

我的目标是实现以下目标：

router.get('/', master.index);
router.post('/search', master.search);
router.get('/ot', ot.index);
router.get('/ot/:id', ot.getById);

总节点js noob，我真的很感谢你的帮助:)

    所以这应该工作：因为 index.js 将其更改为：

    'use strict';

const Koa = require('koa');
const Router = require('koa-router');
const keygrip = require("keygrip");
// const r = require('rethinkdbdash')(); // not needed in this code at the moment
const views = require('koa-views');
const Twig = require('twig');
const twig = Twig.twig;

const app = new Koa(); // Init Koa
const router = new Router(); //Init router

//configure VIEWS
app.use(views(__dirname + '/views/', { extension: 'twig', map: {twig: 'twig' }}))

//Initialize controllers
var ot = require(__dirname+'/controllers/ot.js');

app.keys = ['im a newer secret', 'i like turtle']; // not needed in this code at the moment

router
  .get('/', async function (ctx, next) {
      await ctx.render('index', {
          message: 'Hello world! <3'
      });
  });

// routes from ot.js
router.get('/ot', ot.index);

app
    .use(router.routes())
    .use(router.allowedMethods());
app.listen(3000);
console.log('server listen on http://localhost:3000');

    然后您的 controllers/ot.js 可能如下所示：

    'use strict';

exports.index = async function (ctx, next) {
    await ctx.render('index', {
        message: 'Hello - FROM ot/index'
    });
};

exports.someOther = async function (ctx, next) {
    // some other function
};

    我的样本 views/index.twig

    <!DOCTYPE html>
<html>
    <head>
        <title>My Webpage</title>
    </head>
    <body>
        <h1>My Webpage</h1>
        {{ message }}
    </body>
</html>

    两条路线 localhost:3000/ 和 localhost:3000/ot 现在都可以使用 . 这里缺少RethinkDB部分，因为您没有提供任何示例代码 . 希望有所帮助 .
