Microservices Communication in .NET Using gRPC

By: Fiodar Sazanavets

Overview of this book

Explore gRPC's capabilities for faster communication between your microservices using the HTTP/2 protocol in this practical guide that shows you how to implement gRPC on the .NET platform. gRPC is one of the most efficient protocols for communication between microservices that is also relatively easy to implement. However, its official documentation is often fragmented and.NET developers might find it difficult to recognize the best way to map between C# data types and fields in gRPC messages. This book will address these concerns and much more. Starting with the fundamentals of gRPC, you'll discover how to use it inside .NET apps. You’ll explore best practices for performance and focus on scaling a gRPC app. Once you're familiar with the inner workings of the different call types that gRPC supports, you'll advance to learning how to secure your gRPC endpoints by applying authentication and authorization. With detailed explanations, this gRPC .NET book will show you how the Protobuf protocol allows you to send messages efficiently by including only the necessary data. You'll never get confused again while translating between C# data types and the ones available in Protobuf. By the end of the book, you’ll have gained practical gRPC knowledge and be able to use it in .NET apps to enable direct communication between microservices.

Questions

  1. How do you get the gRPC server to send detailed error diagnostics to the client?
    1. You have to add your custom logic to the gRPC service implementation.
    2. You have to use interceptors.
    3. You can set the EnableDetailedErrors option on the server.
    4. You have to throw RpcException.
  2. How do you enable the middleware of the gRPC service on ASP.NET Core to output debugging information?
    1. Set the Grpc entry in the logging settings to Debug.
    2. Attach event listeners to the gRPC assembly.
    3. Insert a custom logger into the gRPC channel.
    4. This is not possible.
  3. What is the easiest way to determine if an error came from the inner gRPC middleware on ASP.NET Core?
    1. You can do this by looking up special keywords in the exception message.
    2. You can do this by checking if the exception is of the RpcException type.
    3. You can do this by checking if the exception is of the HttpException type.
    4. You can do this by looking up special numeric codes in the exception message.
  4. How can you pass a shared application logger...
