NBB.MultiTenancy.Identification

NBB.MultiTenancy.Identification

This package provides abstractions for tenant identification like:

• Identification service - obtains the tenant ID from the context (includes abstraction and default implementation)
• Identification strategy - the default tenant identification service tries to apply a list of identification strategies to obtain the tenant ID. A strategy uses tenant resolvers and identifiers.
• Tenant resolver - obtains a tenant token from the context. The tenant token is a string that can be used to identify a tenant.
• Tenant identifier- obtains the tenant ID from the tenant token.

NuGet install

dotnet add package NBB.MultiTenancy.Identification

Registration

The following example registers a tenant identification service that uses the following strategy:

• try to get a tenant token using the resolver JwtBearerTokenResolver (from Jwt token), from the claim "tid"
• try to get a tenant token using the resolver HeaderHttpTokenResolver from the header key "TenantId"
• if a tenant token could not be resolved in the previous step, try to get one using the resolver QueryStringHttpTokenResolver, from the key "TenantId"
• if a token was resolved, obtain the tenant ID using the identifier IdTenantIdentifier

    services.AddTenantIdentificationService()
        .AddTenantIdentificationStrategy<IdTenantIdentifier>(builder => builder
            .AddTenantTokenResolver<JwtBearerTokenResolver>(DefaultJwtClaimStringParamName)
            .AddTenantTokenResolver<HeaderHttpTokenResolver>(DefaultTenantHttpHeaderName)
            .AddTenantTokenResolver<QueryStringHttpTokenResolver>(DefaultTenantQueryStringParamName)
        );
