查詢IP地理位置或國家

分享如何從 IP 知道所屬城市或國家，這還滿神奇的，不需要連什麼web service，call 什麼 Restful API，直接透過資料庫離線或批次查詢mapping。

說明，透過下面的 source code, 第1次取得地區為 US, 第2次測試結果為 TW.

source code:

import geoip2.database
reader = geoip2.database.Reader(‘./GeoLite2-Country.mmdb’)
response = reader.country(‘218.161.70.131’)
print response.country.iso_code

測試 ip: 218.161.70.131 結果顯示 TW.

測試 ip: 128.101.101.101 結果顯示 US.
