protorpcProtobuf-RPC 实现

protorpc 是针对Go语言和C++的Protobuf-RPC实现. 其中C++版本还附加了XML的支持.

示例代码：

package server

import (
    "code.google.com/p/goprotobuf/proto"
    "errors"

    "./arith.pb"
)

type Arith int

func (t *Arith) Multiply(args *arith.ArithRequest, reply *arith.ArithResponse) error {
    reply.Val = proto.Int32(args.GetA() * args.GetB())
    return nil
}

func (t *Arith) Divide(args *arith.ArithRequest, reply *arith.ArithResponse) error {
    if args.GetB() == 0 {
        return errors.New("divide by zero")
    }
    reply.Quo = proto.Int32(args.GetA() / args.GetB())
    reply.Rem = proto.Int32(args.GetA() % args.GetB())
    return nil
}

func main() {
    arith.ListenAndServeArithService("tcp", ":1984", new(Arith))
}
