cloudflare 的 development mode－Hello World

如果你有使用 cloudflare 的cdn 功能
預設的cache 是啟用的
但是如果你目前需要頻繁更新網頁
想要看到即時的畫面，又不要不斷的清cache

cloudflare 提供了 development mode 的功能
啟用development mode 之後的三個小時內
cloudflare 會幫你bypass 所有的cache
直到你手動關閉或是三個小時後自動關閉

另外也提供api 可以不用登入管理介面操作

example:
取得目前 development mode 狀態
curl -X GET "https://api.cloudflare.com/client/v4/zones/YOUR-ZONE-ID/settings/development_mode" \
-H "X-Auth-Email: user@example.com" \
-H "X-Auth-Key: YOUR-API-KEY" \
-H "Content-Type: application/json"
