Subdomain Mapping in ASP.NET Boilerplate
In AbpTenants table in the database. You can add your custom properties to Tenant class.
AbpTenant class defines some basic properties, the most important properties are:
- TenancyName: This is a unique name of a tenant in the application. It should not be changed normally. It can be used to allocate subdomains to tenants like ‘mytenant.mydomain.com’. Tenant.TenancyNameRegex constant defines the naming rule.
- Name: An arbitrary, human-readable, long name of the tenant.
- IsActive: True, if this tenant can use the application. If it’s false, no user of this tenant can login to the system.
Please find below the code segments that do this:
// Part 1 - Initialize cache (or inject depending on scenario)
ITypedCache<string, Tenant> _tenantCache;
using (var cacheManager = AbpBootstrapper.IocManager.ResolveAsDisposable<CacheManagerBase>())
{
_tenantCache = cacheManager.Object.GetCache<string, Tenant>("TenantCache");
}
// Part 2 - Detect subdomain & look up tenant
if (Request.Url.HostNameType == UriHostNameType.Dns)
{
// Try to get tenant name from sub-domain
string tenantName = Request.Url.Host.Split('.')[0];
Tenant t = _tenantCache.Get(tenantName,
() =>
{
// attempt to look up
return AsyncContext.Run<Tenant>(() => GetTenant(tenantName));
});
// Part 3 - Set the current tenant
if (t != null)
{
// Set tenant ID
}
}
private async Task<Tenant> GetTenant(string tenantName)
{
TenantManager manager = AbpBootstrapper.IocManager.Resolve<TenantManager>();
Tenant t = await manager.FindByTenancyNameAsync(tenantName);
return t;
}
