問題描述
所以，我在上一個問題中被告知我可以使用 MaxMind 提供的 數據庫來確定位置.
So, I was told in my previous question that I can use the databases provided by MaxMind to determine locations.
所以，我從他們的網站下載了他們的數據庫.它們是 csv 文件并在 Excel 中打開.
So, I got their databases downloaded from their site. They are csv files and open up in Excel.
InetAddress ip = InetAddress.getLocalHost() 是我獲取計算機 IP 的方式.從那里我做 String justIP = ip.getHostAddress()
InetAddress ip = InetAddress.getLocalHost() is how I get the IP of my computer. From there I do String justIP = ip.getHostAddress()
我的問題是:
justIP 解析為城市位置???我對此很陌生，因此將不勝感激.
My question is:
justIP to a city location using the DB I just downloaded ??? I am new to this so a little help will be appreciated.
其中一個文件包含三列.startIPNum、endIPNum 和 locID 我不知道這些是做什么的，但我猜 locID 映射到一個城市和國家在另一個文件中的位置.
One of the files has three columns. startIPNum, endIPNum and locID I do not know what these do but I guess locID maps to a city and country location in the other file.
