Deno 之 HTTP 模塊

std/Http

import { serve } from "https://deno.land/std/http/server.ts";
const s = serve({ port: 8000 });
console.log("http://localhost:8000/");
for await (const req of s) {
  req.respond({ body: "Hello World\n" });
}

• Server

  }

可迭代的異步服務

Server 類的實例是可迭代的，內部包好 req, res 響應對象

• Server 內部實現
