Edge Security Acceleration：請求一個頁面並返回

代碼

/**
 * 樣本為請求https://www.aliyundoc.com/index.html並返回
 * 測試是請將url和someHost替換為您自己的地址
 */
const someHost = "https://www.aliyundoc.com/"
const url = someHost + "index.html"
/**
 * gatherResponse函數將response處理成string並返回
 * 在1個非同步函數中使用await gatherResponse(..)確保完整拿到response的body
 */
async function gatherResponse(response) {
  const headers = response.headers
  const contentType = headers.get("content-type") || ""
  if (contentType.includes("application/json")) {
    return JSON.stringify(await response.json())
  } else if (contentType.includes("application/text")) {
    return response.text()
  } else if (contentType.includes("text/html;charset=UTF-8")) {
    return response.text()
  } else {
    return response.blob()
  }
}

async function handleRequest(request) {
  const init = {
    headers: {
      "content-type": "text/html;charset=UTF-8",
    },
  }
  const response = await fetch(url, init)
  const results = await gatherResponse(response)
  return new Response(results, init)
}

addEventListener("fetch", event => {
  return event.respondWith(handleRequest(event.request))
})

結果

ER發出fetch子請求，得到https://www.aliyundoc.com/index.html 的內容並返回給用戶端。
