HeXuShi.Extensions.NoWWW

nuget install

change www.site.com to site.com in asp.net core web app.

using HeXuShi.Extensions;

public class Startup

    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)

        ...
        app.UseNoWWW();
        ...
    }
}

HeXuShi.Extensions.IsChinaIp

nuget install

Use example

IsChinaIp.Setup();//Setup can be called multiple times, but only on the first initialization
Console.WriteLine("ipv4 test:" + IsChinaIp.VerifyIPv4("183.192.62.65"));
Console.WriteLine("ipv6 test:" + IsChinaIp.VerifyIPv6("2400:da00::6666"));

run test result :

49) ipv4 test:True

HeXuShi.Extensions.JumpToCN

nuget install

Demo site

When you use China mainland ip access, change xx.com or xx.anything to xx.cn,help you jump to cn(china) domain suffix.

No longer based on this project https://github.com/lionsoul2014/ip2region/, But still very grateful lionsoul2014

Because we only need to simply query Chinese ip, so we don't need to pre-install any project files (such as db files).

Use examples:

normal example first :

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.JumpToCN();
        ...
    }
}

normal example second :

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.JumpToCN(".com");
        ...
    }
}

complex example first :

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.ComplexJumpToCN(".cn", string.Empty, HeXuShi.Extensions.JumpOption.OnlyTo_SpecSuffix);
        ...
    }
}

complex example second :

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.ComplexJumpToCN("asp.net", string.Empty, HeXuShi.Extensions.JumpOption.OnlyTo_SpecDomain);
        ...
    }
}

complex example third :

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.ComplexJumpToCN("asp.net", "github.com", HeXuShi.Extensions.JumpOption.DomainTo_SpecDomain);
        ...
    }
}

run test result :

49) ipv4 test:True
runTime:00:00:00.1628871
49) ipv6 test:True
runTime:00:00:00.0010261
48) ipv4 test:True
runTime:00:00:00.0006312
48) ipv6 test:True
runTime:00:00:00.0001385

HeXuShi.Extensions.JumpToCN normal api

This project normal api(app.JumpToCN) will run into 3 states:

first state:

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.JumpToCN();
        ...
    }
}

When you use China mainland ip access, you will be redirected to the .cn suffix domain name, but if you currently use the .cn suffix domain name to access, regardless of any region's ip access, the current suffix domain name will be maintained.

second state:

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.JumpToCN(".com");
        ...
    }
}

When you use China mainland ip access, you will be redirected to the .cn suffix domain name. If it is a non-Chinese mainland ip access, use the .cn suffix domain name to access, it will jump to the specified .com suffix domain name.

third state:

The current region is not found, the query module has an exception.the current suffix domain name will be maintained.

HeXuShi.Extensions.JumpToCN complex api

This project complex api(app.ComplexJumpToCN) has four options to build multiple possibilities

    public enum JumpOption
    {
        OnlyTo_SpecSuffix,//Only jump to specify suffix
        OnlyTo_SpecDomain,//Only jump to specify domain
        SuffixTo_SpecSuffix,//specify suffix to specify suffix,
        DomainTo_SpecDomain,//specify domain to specify domain,
    }

I hope that you have not been confused, in the final analysis, just check the suffix, domain name, and mainland China ip, judge the jump

Learning through unit testing

HeXuShi.Extensions.JumpToCN OnlyTo_SpecSuffix

HeXuShi.Extensions.BlockChina normal api

run:

using HeXuShi.Extensions;

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.BlockChina();
        ...
    }
