Course Introduction：The correct default gateway address must be set to ensure that data packets are sent correctly. This can be configured in three ways: 1. Manually set the IP and gateway in the TCP/IPv4 properties; 2. Use the command prompt with administrator rights to execute the netsh command for temporary configuration; 3. Modify the WAN port gateway through the router management interface, which indirectly affects the client.

Course Introduction：Use Go and gRPC-Gateway to expose the gRPC service to RESTfulHTTPAPI. First, you need to define the gRPC service in the .proto file and add the google.api.http annotation to map the HTTP endpoint. Then install the protoc plugin and generate the gRPC and gRPC-Gateway codes. Then implement the gRPC server logic and start the gRPC service in Go. Then run the gRPC-Gateway reverse proxy through a separate HTTP server to convert the HTTP/JSON request into a gRPC call. Finally, run the gRPC service and HTTP gateway service at the same time, and you can access the gRPC function through the REST interface.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
