之前介紹了使用 Cloudflare worker來進行客戶端 IP調查的小程式(https://diary.tw/archives/2182), 最近新增一些功能上來.

1. 利用瀏覽器訪問時, 會加上完整的 html, 並增加了 Google Analytics 追蹤碼, 來記錄使用的次數.
2. 若是利用非瀏覽器訪問時, 會直接輸出純文字 ip 而不會加上其他的內容, 例如: curl https://ip.diary.tw/
3. 利用這個 geoplugin 這個免費的 API 功能來查找對應 IP的資訊, 請參考這個 API文件說明: https://www.geoplugin.com/webservices/json, 使用方式為 https://ip.diary.tw/?data=geo, 可以查找對應 IP的所在地與該地區使用貨幣與匯率. 輸出範例如下:

{
  "geoplugin_request":"12.34.56.78",
  "geoplugin_status":200,
  "geoplugin_delay":"1ms",
  "geoplugin_credit":"Some of the returned data includes GeoLite2 data created by MaxMind, available from <a href='https:\/\/www.maxmind.com'>https:\/\/www.maxmind.com<\/a>.",
  "geoplugin_city":"New Taipei City",
  "geoplugin_region":"New Taipei City",
  "geoplugin_regionCode":"NWT",
  "geoplugin_regionName":"New Taipei City",
  "geoplugin_areaCode":"",
  "geoplugin_dmaCode":"",
  "geoplugin_countryCode":"TW",
  "geoplugin_countryName":"Taiwan",
  "geoplugin_inEU":0,
  "geoplugin_euVATrate":false,
  "geoplugin_continentCode":"AS",
  "geoplugin_continentName":"Asia",
  "geoplugin_latitude":"24.9466",
  "geoplugin_longitude":"121.586",
  "geoplugin_locationAccuracyRadius":"20",
  "geoplugin_timezone":"Asia\/Taipei",
  "geoplugin_currencyCode":"TWD",
  "geoplugin_currencySymbol":"NT$",
  "geoplugin_currencySymbol_UTF8":"NT$",
  "geoplugin_currencyConverter":32.0408
}

由於原來的 ip geolocation service 已變成只有付費方案了如下:

{
  "geoplugin_status":403,
  "geoplugin_message": "geoPlugin API is no longer available for free use. To continue access, please upgrade to a paid plan",
  "geoplugin_url": "https://www.geoplugin.com/subscription"
}

所以改用仍有 free tier 的另一個服務: https://ipgeolocation.io/, 免費就有一定的使用量可供應用, API 也簡單, 只需要註冊帳戶, 就可以拿 API Token 去訪問取得資訊, API 使用方式請參考:

https://ipgeolocation.io/documentation/ip-location-api.html

調整一下程式碼, 之後訪問 https://ip.diary.tw/?data=geo 時, 就可以拿到對應的回傳結果如下:
