In Go, observer mode can be implemented through interfaces and channels, the Observer interface can be defined, the Observer interface includes the Update method, the Subject structure maintains the observer list and message channel, add observers through Attach, Notify sends messages, listengoroutine asynchronous broadcast updates, specific observers such as EmailService and LogService implement the Update method to handle notifications, the main program registers the observer and triggers events, and realizes a loosely coupled event notification mechanism, which is suitable for event-driven systems, logging and message notifications and other scenarios.

The steps to communicate between Go microservices using gRPC are: 1. Use ProtocolBuffers to define the service interface and message types, and write .proto files; 2. Install the protoc compiler and Go plug-in to generate greeter.pb.go and greeter_grpc.pb.go code files; 3. Implement the gRPC server, register the service and listen to the specified ports; 4. Create a gRPC client, establish a connection and call remote methods; 5. Run the server and client respectively to verify communication; 6. Follow best practices, including enabling TLS, using interceptors, error handling and version control; 7. Adopt a clear project structure for easy maintenance and updates. These steps allow for high efficiency

Yes, using the Go standard library, you can build a RESTful API, handle requests through net/http, encoding/json, and context management context, combined with http.ServeMux routing, manual path resolution, middleware encapsulation and appropriate error handling, you can achieve a lightweight, controllable RESTful service without external frameworks, and ultimately improve maintainability with a modular structure and fully master the underlying HTTP mechanism.
