Country Tag Helper–part 5

Now the Country Tag Helper supports .NET Standard 2.0 . This means that support .NET Core 2.0 .

Also, I have made a NuGET package in order to install on every .NET Core 2.0 application with explanations: https://www.nuget.org/packages/CountryTagHelper 

The only trouble here was to add references and make documentation in VS2017 about package ( see https://docs.microsoft.com/en-us/nuget/guides/create-net-standard-packages-vs2017 )

As I said , the source is at GitHub https://github.com/ignatandrei/CountryTagHelper and demo at http://countrytaghelper.apphb.com/

What remains to be done:

localized
add select2 with image flags   

provider / dependency injection for FromIP
readme.md / wiki on github

Country Tag Helper–part 4

 

Now I want to see somewhere in order to prove it Ii s right. I choose https://appharbor.com/ because it is free – and can not beat free for free source.

I made github integration and modify the .csproj file accordingly to https://support.appharbor.com/discussions/problems/90387-is-net-core-supported-yet 

The result is at http://countrytaghelper.apphb.com/ 

Also , I have to modify the code source to get the ip of the user :

string GetUserIP(ViewContext vc)
        {
            StringValues headerFwd;
            if (ViewContext.HttpContext?.Request?.Headers?.TryGetValue("X-Forwarded-For", out headerFwd) ?? false)
            {
                string rawValues = headerFwd.ToString();
                if (!string.IsNullOrWhiteSpace(rawValues))
                {
                    return rawValues.Split(',')[0];
                }

            }
            return ViewContext.HttpContext?.Connection?.RemoteIpAddress?.ToString();

        }

where ViewContext is

 [ViewContext]
        public ViewContext ViewContext { get; set; }

Country Tag Helper – part 3

Adding empty item – easy peasy. Just append "<option selected style=’display: none’ value=”></option>";

 

if (ASPCountryEmpty)
                {
                    string empty = "<option selected style='display: none' value=''></option>";
                    output.Content.AppendHtml(empty);
                }

For getting the IP, I was trying to balance the 2 variants: downloading GeoIP database (https://dev.maxmind.com/geoip/geoip2/geolite2/) or calling http://freegeoip.net/ .

I do call http://freegeoip.net/ – and the next point is to use Dependency Injection … or a provider to do that.

For the moment, the code is:

 private async Task<string> GetCountryCodeFromIP(string ip)
        {
            //ip= "188.25.145.65";
            var url = "http://freegeoip.net/csv/"+ip;
            var request = WebRequest.Create(url);
            request.Method = "GET";
            using (var wr = await request.GetResponseAsync())
            {
                using (var receiveStream = wr.GetResponseStream())
                {
                    using (var reader = new StreamReader(receiveStream, Encoding.UTF8))
                    {
                        string content = reader.ReadToEnd();
                        return content.Split(',')[1];
                    }
                        
                }
                    
            }


        }
