Interface HttpClientProvider

@DoNotInherit public interface HttpClientProvider
Provider for HTTP clients to interact with other services over HTTP.

HttpClientProvider enables HTTP endpoints and other components to make outbound HTTP calls to other services, both within the same Akka project and to external services on the internet.

Service-to-Service Communication: When calling other Akka services deployed in the same project, use the service name without protocol or domain. The runtime handles routing, encryption, and authentication automatically.

External Service Communication: For external services, provide full URLs with http:// or https:// protocols. These calls go over the public internet and require appropriate authentication.

Usage in Endpoints: Inject HttpClientProvider into endpoint constructors to access HTTP client functionality. The provider creates configured HTTP clients for specific services or URLs.

Security: Service-to-service calls within the same project are automatically secured with mutual TLS and service identity verification. External calls require manual authentication setup.

Not for user extension, instances provided by the SDK through dependency injection.

  • Method Details

    • httpClientFor

      HttpClient httpClientFor(String serviceName)
      Returns a HttpClient to interact with the specified HTTP service.

      If the serviceName is a service name without protocol or domain the client will be configured to connect to another service deployed with that name on the same Akka project. The runtime will take care of routing requests to the service and keeping the data safe by encrypting the connection between services and identifying the client as coming from this service.

      If it is a full dns name prefixed with "http://" or "https://" it will connect to services available on the public internet.
