Access host side with host.domain.com #9668

Hey, we've done this many times in our projects.

So we create a MyDomainTenantResolveContributor.cs in the root folder of the *.Web.Core project, with the following content:

public class MyDomainTenantResolveContributor : ITenantResolveContributor, ITransientDependency
{
private readonly IHttpContextAccessor _httpContextAccessor;
private readonly IWebMultiTenancyConfiguration _multiTenancyConfiguration;
private readonly ITenantStore _tenantStore;
private readonly ILocalizationManager _localizationManager;
public MyDomainTenantResolveContributor(
IHttpContextAccessor httpContextAccessor,
IWebMultiTenancyConfiguration multiTenancyConfiguration,
ITenantStore tenantStore,
ILocalizationManager localizationManager)
{
_httpContextAccessor = httpContextAccessor;
_multiTenancyConfiguration = multiTenancyConfiguration;
_tenantStore = tenantStore;
_localizationManager = localizationManager;
}
public int? ResolveTenantId()
{
    if (_multiTenancyConfiguration.DomainFormat.IsNullOrEmpty())
    {
        return null;
    }

    var httpContext = _httpContextAccessor.HttpContext;
    if (httpContext == null)
    {
        return null;
    }

    var hostName = httpContext.Request.Host.Host.RemovePreFix("http://", "https://").RemovePostFix("/");
    var domainFormat = _multiTenancyConfiguration.DomainFormat.RemovePreFix("http://", "https://").Split(':')[0].RemovePostFix("/");
    var result = new FormattedStringValueExtracter().Extract(hostName, domainFormat, true, '/');

    var tenancyName = result.Matches[0].Value;

    if (string.Equals(tenancyName, "host", StringComparison.OrdinalIgnoreCase))
    {
        return null;
    }

    var tenantInfo = _tenantStore.Find(tenancyName);
    if (tenantInfo == null)
    {
        var noTenantFound = _localizationManager.GetString(AppConsts.LocalizationSourceName, "NoTenantFound");
        var noTenantFoundDetail = _localizationManager.GetString(AppConsts.LocalizationSourceName, "NoTenantFoundDetail");
        throw new UserFriendlyException(noTenantFound, noTenantFoundDetail);
    }

    return tenantInfo.Id;
}

}

And then we add a reference to it in our PreInitialize method of the *WebMvcModule.cs: if (!_env.IsDevelopment() && !_env.IsStaging()) { Configuration.MultiTenancy.Resolvers.Insert(0, typeof(MyDomainTenantResolveContributor)); }

We also added the same line in the PreInitialize method of the *WebCoreModule.cs, but not sure if that is needed though.
