编写路由

基础用法

// router.js
router.get('/admin/:id', controller.admin.index);

// controller
async index() {
    const { ctx } = this;
    // 获取路由get传值参数（路由:id）
    ctx.params;
    // 获取url的问号get传值参数
    ctx.query;
}

资源路由

// app/router.js
module.exports = app => {
  const { router, controller } = app;
  router.resources('posts', '/api/posts', controller.posts);
  // app/controller/v1/users.js
  router.resources('users', '/api/v1/users', controller.v1.users); 
};

上面代码就在 /posts 路径上部署了一组 CRUD 路径结构，对应的 Controller 为 app/controller/posts.js 接下来， 你只需要在 posts.js 里面实现对应的函数就可以了。

Method	Path	Route Name	Controller.Action
GET	/posts	posts	app.controllers.posts.index
GET	/posts/new	new_post	app.controllers.posts.new
GET	/posts/:id	post	app.controllers.posts.show
GET	/posts/:id/edit	edit_post	app.controllers.posts.edit
POST	/posts	posts	app.controllers.posts.create
PUT	/posts/:id	post	app.controllers.posts.update
DELETE	/posts/:id	post	app.controllers.posts.destroy

// app/controller/posts.js

// 列表页
exports.index = async () => {};
// 新增表单页
exports.new = async () => {};
// 新增逻辑
exports.create = async () => {};
// 详情页
exports.show = async () => {};
// 编辑表单页
exports.edit = async () => {};
// 更新逻辑
exports.update = async () => {};
// 删除逻辑
exports.destroy = async () => {};

路由分组

// app/router.js
module.exports = app => {
  require('./router/news')(app);
  require('./router/admin')(app);
};

// app/router/news.js
module.exports = app => {
  app.router.get('/news/list', app.controller.news.list);
  app.router.get('/news/detail', app.controller.news.detail);
};

// app/router/admin.js
module.exports = app => {
  app.router.get('/admin/user', app.controller.admin.user);
  app.router.get('/admin/log', app.controller.admin.log);
};
