// Importing Required Files And Packages Here.
import { Application, Router, send } from "https://deno.land/x/oak/mod.ts";
import {

回答1:

All GET request to /test route is intercepted by static content middleware, move that middleware function after to common middleware setup

app.use(viewEngine(oakAdapter, ejsEngine));
app.use(router.routes());
app.use(router.allowedMethods());

// Serving A Static Folder Here.
app.use(async (ctx,next)=>{
  await send(ctx,ctx.request.url.pathname,{
      root :`${Deno.cwd()}/public`
  })
  next();
})
