abstract class GRPC::ClientInterceptor

• GRPC::ClientInterceptor
• Reference
• Object

Overview

ClientInterceptor is the base class for client-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 LoggingInterceptor < GRPC::ClientInterceptor def call(method_path, request, ctx, next_call) STDERR.puts "→ #{method_path}" result = next_call.call(method_path, request, ctx) STDERR.puts "← #{result[1].code}" result end end

channel = GRPC::Channel.new("localhost:50051", interceptors: [LoggingInterceptor.new] of GRPC::ClientInterceptor)
