来自 IP 地址的经度和纬度值

问题描述

是否可以从asp.net中的IP地址获取经度和纬度值?如果可能的话，请告诉我如何获得这个.

Is it possible to get the longitude and latitude value from IP address in asp.net? If it is possible, please let me know how can I get this.

推荐答案

MaxMind Geolite city免费.如果它不够好，您显然可以升级到更准确的付费版本.我无法评价付费版本的质量，因为我从未使用过它.

MaxMind Geolite city is free. If it is not good enough, you can apparently upgrade to a more accurate paid-version. I can't speak for the quality of the paid version, as I have never used it.

如果您喜欢您的 SQL，请下载 CSV 版本.将其加载到您选择的数据库中，然后查询.

If you like your SQL, download the CSV version. Load it into your database of choice, and query away.

更快、更节省空间的选择是下载文件二进制blob版本同一个数据库，然后使用C#类查询.

The faster and space-efficient option is to download the file binary blob version of the same database, and then use the C# class to query it.

另外，我发现 ipinfodb.com 很有用.查询是通过简单的 HTTP GET.例如，要对 stackoverflow.com 进行地理定位，请尝试:

Alternatively, I have found ipinfodb.com to be useful. Query is by simple HTTP GET. For example, to geolocate stackoverflow.com try:

http://ipinfodb.com/ip_query.php?timezone=false&ip=69.59.196.211

这将返回一个包含纬度和经度的 XML 文件，如下所示:

This will return an XML file containing latitude and longitude, that looks like:

<Response>
  <Ip>69.59.196.211</Ip>
  <Status>OK</Status>
  <CountryCode>US</CountryCode>
  <CountryName>United States</CountryName>
  <RegionCode>41</RegionCode>
  <RegionName>Oregon</RegionName>
  <City>Corvallis</City>
  <ZipPostalCode>97333</ZipPostalCode>
  <Latitude>44.4698</Latitude>
  <Longitude>-123.343</Longitude>
</Response>
