Deno Router基本应用

一起来完成以下步骤:

1. 创建一个简单的Router
2. 分别创建user(以user开头的url)和admin(以admin开头的url) 的Router
3. 实现动态uri的Router

#main.ts

import { Application, Router } from "https://deno.land/x/oak/mod.ts";
import UserRouter  from "./user-router.ts";
import AdminRouter  from "./admin-router.ts";

const app = new Application();
const router = new Router();  router.get("/",(ctx) =>{  ctx.response.body="Hello World"; })   app.use(router.routes()); app.use(router.allowedMethods());  app.use(UserRouter.routes()); app.use(UserRouter.allowedMethods()); app.use(AdminRouter.routes()); app.use(AdminRouter.allowedMethods());  await app.listen({ port:8000 }); 

#admin-router.ts

import { Router } from "https://deno.land/x/oak/mod.ts";

const AdminRouter = new Router({prefix:"/admin"}); //以admin开头的uri
AdminRouter.get("/",(ctx) =>{
    ctx.response.body ="Hello Admin";
})  export default AdminRouter; 

#user-router.ts

import { Router } from "https://deno.land/x/oak/mod.ts";

const UserRouter = new Router({prefix:"/user"}); //以user开头的uri

UserRouter.get("/",(ctx) =>{  ctx.response.body ="Hello User"; }).get("/:id",(ctx) =>{  ctx.response.body = "the user is is "+ ctx.params.id; })  export default UserRouter; 

完
