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
