没rest怎么行？

曾经rest被吹的玄之又玄，唯恐不谈rest就没有x格，其实rest理解起来还是蛮简单的

最简单的入门是理解crud方法，参考rails的scaffold即可

  1. rails g scaffold user name:string password:string

打印路由

  1. blog git:(master) ✗ rake routes
  2.    Prefix Verb   URI Pattern               Controller#Action
  3.     users GET    /users(.:format)          users#index
  4.           POST   /users(.:format)          users#create
  5.  new_user GET    /users/new(.:format)      users#new
  6. edit_user GET    /users/:id/edit(.:format) users#edit
  7.      user GET    /users/:id(.:format)      users#show
  8.           PATCH  /users/:id(.:format)      users#update
  9.           PUT    /users/:id(.:format)      users#update
  10.           DELETE /users/:id(.:format)      users#destroy

是不是代码非常清晰？

既然它是最佳实践，我们也没必要再自己搞一套,只需要因express制宜即可

  • GET /orders[/] => order.list()
  • GET /orders/new => order.new()
  • GET /orders/:id => order.show()
  • GET /orders/:id/edit => order.edit()
  • POST /orders[/] => order.create()
  • PATCH /orders/:id => order.update()
  • DELETE /orders/:id => order.destroy()

在app/routes/order.js里

  1. var express = require('express');
  2. var router = express.Router();
  4. // mount all middlewares in app/middlewares, examples:
  5. // 
  6. // router.route('/')
  7. //  .get($middlewares.check_session_is_expired, $.list)
  8. //  .post($.create);
  9. // 
  10. var $middlewares  = require('mount-middlewares')(__dirname);
  12. // core controller
  13. var $ = require('mount-controllers')(__dirname).orders_controller;
  16. /**
  17.  * Auto generate RESTful url routes.
  18.  *
  19.  * URL routes:
  20.  *
  21.  *  GET    /orders[/]        => order.list()
  22.  *  GET    /orders/new       => order.new()
  23.  *  GET    /orders/:id       => order.show()
  24.  *  GET    /orders/:id/edit  => order.edit()
  25.  *  POST   /orders[/]        => order.create()
  26.  *  PATCH  /orders/:id       => order.update()
  27.  *  DELETE /orders/:id       => order.destroy()
  28.  *
  29.  */
  31. router.get('/new', $.new);  
  32. router.get('/:id/edit', $.edit);
  34. router.route('/')
  35.   .get($.list)
  36.   .post($.create);
  38. router.route('/:id')
  39.   .patch($.update)
  40.   .get($.show)
  41.   .delete($.destroy);
  43. module.exports = router;

于是所有东西就都丢到controller里去。

整个世界顿时就清净了

有了Rest，格调也有了。。。。
