- proto编写

echo_service.proto

syntax = "proto3";

package goya.rpc.echo; // 命名空间

option cc_generic_services = true; // 是否生成C代码
 
message EchoRequest {
    string message = 1;
}

message EchoResponse {
    string message = 1;
}

service EchoServer {
  rpc Echo(EchoRequest) returns(EchoResponse);
}

- CMakeList.txt对proto文件的解析

find_package(Protobuf REQUIRED)
file(GLOB protofiles "${PROJECT_SOURCE_DIR}/sample/echo/*.proto")
PROTOBUF_GENERATE_CPP(PROTOSRCS PROTOHDRS ${protofiles})
