C++ RPC Framework Guide: Implementation Steps

Using an RPC (Remote Procedure Call) framework in C++ usually involves the following steps:

1. Define remote service interface: Firstly, we need to define the remote service interface, which includes the methods and parameters of the service. These interfaces can be described using Interface Definition Language (IDL).
2. Generate client and server framework code: Utilize the tools provided by the RPC framework to generate the necessary client and server framework code based on the defined remote service interface, which includes the communication mechanisms needed for remote procedure calls.
3. Implementing remote services: on the server side, implement the methods defined in the remote service interface based on the generated framework code to handle remote invocation requests initiated by clients.
4. Invoking remote services: on the client side, use the generated framework code to call the methods defined in the remote service interface, send remote call requests, and receive the results returned by the server.
5. Deployment and Execution: Deploy the server and client code to their respective machines, then run the server and client programs to achieve remote procedure calls.

Popular C++ RPC frameworks such as Thrift and gRPC provide a wide range of features and tools to simplify the implementation and management of remote procedure calls. Utilizing these frameworks enables easy realization of cross-network remote communication, leading to improved system scalability and maintainability.
