Interceptors for Security
Use gRPC interceptors to centralize security concerns like authentication and logging across services.
Intro to gRPC Interceptors
Interceptors are a powerful feature in gRPC, acting like middleware that can inspect and modify requests and responses. They allow you to centralize common logic that applies to multiple service calls.
Think of them as gates or checkpoints your requests pass through.
Why Use Interceptors?
Interceptors are perfect for handling cross-cutting concerns. Instead of repeating code in every service method, you can manage things like:
- Authentication
- Authorization
- Logging & Monitoring
- Request validation
This keeps your core service logic clean and focused.
