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/koa制宜即可

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

在app/routes/locations.js里

  1. "use strict";
  3. var router = require('koa-router')();
  4. const co = require('co');
  6. var $middlewares  = require('mount-middlewares')(__dirname);
  8. // core controller
  9. var $ = require('mount-controllers')(__dirname).locations_controller;
  11. /**
  12.  * Auto generate RESTful url routes.
  13.  *
  14.  * URL routes:
  15.  *
  16.  *  GET    /locations[/]        => location.list()
  17.  *  GET    /locations/new       => location.new()
  18.  *  GET    /locations/:id       => location.show()
  19.  *  GET    /locations/:id/edit  => location.edit()
  20.  *  POST   /locations[/]        => location.create()
  21.  *  PATCH  /locations/:id       => location.update()
  22.  *  DELETE /locations/:id       => location.destroy()
  23.  *
  24.  */
  26. router.get('/new', $.new); 
  28. router.get('/:id/edit', $.edit);
  30. router.get('/', $.list);
  32. router.post('/', $.create);
  34. router.get('/:id', $.show);
  36. router.patch('/:id', $.update);
  38. router.delete('/:id', $.destroy);
  40. // -- custom routes
  45. 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。。。。
