IPTools | 中文文档

Quickly query IP information, support domestic and foreign IP information query, support query latitude and longitude, and support geographical location to the city.

IPTools.China:

IPTools.International:

1. IPTools.China

Quickly query China IP information, country, province, city and network operators. Non China IP can only query national information.

(1) Install

Install-Package IPTools.China

(2) Download database file

https://github.com/stulzq/IPTools/raw/master/db/ip2region.db

After the database file is downloaded, put it in your project root directory (same level as the *.csprj file), and set the copy to the output directory.

At the beginning of version 1.2.0, the database file was unembedded into the assembly, which is convenient for updating and reduces the size of the assembly.

(3) Usage

IpTool.Search("your ip address");

eg.

var ipinfo = IpTool.Search("171.210.12.163");
Console.WriteLine(ipinfo.Country); // **
Console.WriteLine(ipinfo.Province); // 四川省
Console.WriteLine(ipinfo.City); // 成都市
Console.WriteLine(ipinfo.NetworkOperator);// 电信

(4) I18N

Not support . So you can't use IpTool.SearchWithI18NAsync().

(5) performance testing

Single thread double for loop queries 65025 IP, takes 170 ms.

(6) Custom DB path

IpToolSettings.ChinaDbPath="";

2. IPTools.International

Quickly query global IP information, support i18n, country, province, city, post code, longitude and latitude.

(1) Install

Install-Package IPTools.International

(2) Download database file

https://github.com/stulzq/IPTools/raw/master/db/GeoLite2-City.mmdb

After the database file is downloaded, put it in your project root directory (same level as the *.csprj file), and set the copy to the output directory.

At the beginning of version 1.2.0, the database file was unembedded into the assembly, which is convenient for updating and reduces the size of the assembly.

(3) Usage

IpTool.Search("your ip address");

eg.

var ipinfo = IpTool.SearchWithI18N("171.210.12.163");
Console.WriteLine(ipinfo.Country); // **
Console.WriteLine(ipinfo.CountryCode); // CN
Console.WriteLine(ipinfo.Province); // 四川省
Console.WriteLine(ipinfo.ProvinceCode); // SC
Console.WriteLine(ipinfo.City); // 成都
Console.WriteLine(ipinfo.Latitude); // 30.6667
Console.WriteLine(ipinfo.Longitude); // 104.6667
Console.WriteLine(ipinfo.AccuracyRadius);// 50

(4) I18N

IpTool.SearchWithI18N("your ip address");

eg.

var ipinfo = IpTool.SearchWithI18N("171.210.12.163","en");//If language code is not set, Chinese will be used by default.
Console.WriteLine(ipinfo.Country); // China
Console.WriteLine(ipinfo.CountryCode); // CN
Console.WriteLine(ipinfo.Province); // Sichuan
Console.WriteLine(ipinfo.ProvinceCode); // SC
Console.WriteLine(ipinfo.City); // Chengdu
Console.WriteLine(ipinfo.Latitude); // 30.6667
Console.WriteLine(ipinfo.Longitude); // 104.6667
Console.WriteLine(ipinfo.AccuracyRadius);// 50

Default language is chinese(zh-CN), How to change?

IpToolSettings.DefaultLanguage = "en";// set default language is english.

(5) Increase query speed

With the following settings, will double the query speed, the principle is to fully load the database file into the memory, the price is that the memory will increase 60-70M, space for time, this should be noted.

IpToolSettings.LoadInternationalDbToMemory = true;

Version >= 1.2.0

(6) performance testing

Single thread double for loop queries 65025 IP, takes 1500 ms(Memory).

(7) Custom DB path

IpToolSettings.InternationalDbPath="";

3. ASP.NET Core Support

IPTools provides an extension method for HttpContext.

usage:

HttpContext.GetRemoteIpInfo();
HttpContext.GetRemoteIpInfo(headerKey); // Get ip from header if you use nginx, haproxy etc.

4. Use both IPTools.China and IPTools.International

Both IPTools.China and IPTools.International implement IIpSearcher. The IpTool class will detect the package you installed during initialization and initialize it only once. IpTool has three static read-only properties, namely DefaultSearcher, IpChinaSearcher, IpAllSearcher.

• DefaultSearcher. IpTool.Search() and IpTool.SearchWithI18N() will use the default Ip searcher.
• IpChinaSearcher. IPTools.China Implemented searcher.
• IpAllSearcher. IPTools.International Implemented searcher.

If you just installed IPTools.China then DefaultSearcher will be IpChinaSearcher and IpAllSearcher will be null.

If you just installed IPTools.International then DefaultSearcher will be IpAllSearcher and IpChinaSearcher will be null.

If you have both components installed at the same time, by default DefaultSearcher will be IpChinaSearcher, IpChinaSearcher and IpAllSearcher will not be null.

To change the default Searcher used by DefaultSearcher, please use the following code, if you have two components installed at the same time, it will take effect.

IpToolSettings.DefalutSearcherType = IpSearcherType.China;
IpToolSettings.DefalutSearcherType = IpSearcherType.International;
