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.
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>
http://forum.ipinfodb.com/上提供了一些 VB.NET 示例代码viewtopic.php?f=7&t=269
