返回1个JSON

代码

async function handler(event) {
  const data = {
    hello: "EdgeRoutine",
  };
  const json = JSON.stringify(data, null, 2);
  return new Response(json, {
    headers: {
      "content-type": "application/json;charset=UTF-8",
    },
  });
}

addEventListener('fetch', (event) => {
  event.respondWith(handler(event));
});

结果
