GRPC::ServerInterceptor

ServerInterceptor is the base class for server-side interceptors. Override call to wrap unary RPCs. Override the streaming variants to intercept server-streaming, client-streaming, or bidi-streaming calls. Unimplemented streaming methods default to a transparent pass-through.

Example: class AuthInterceptor < GRPC::ServerInterceptor def call(method, request, ctx, next_call) unless ctx.metadata["authorization"]? == "Bearer secret" return {Bytes.empty, GRPC::Status.new(GRPC::StatusCode::UNAUTHENTICATED, "bad token")} end next_call.call(method, request, ctx) end end
