开始使用

• 服务端

package main

import (
    "github.com/sunquakes/jsonrpc4go"
    // "github.com/sunquakes/jsonrpc4go/server"// Custom package EOF when the protocol is tcp
)

type Params struct {
    A int `json:"a"`
    B int `json:"b"`
}

type Result = int

type Result2 struct {
    C int `json:"c"`
}

    a := params.A + params.B
    *result = interface{}(a).(Result)
    return nil
}

func (i *IntRpc) Add2(params *Params, result *Result2) error {
    result.C = params.A + params.B
    return nil
}

func main() {
    s, _ := jsonrpc4go.NewServer("http", "127.0.0.1", "3232") // the protocol is http
    // s, _ := jsonrpc4go.NewServer("tcp", "127.0.0.1", "3232") // the protocol is tcp
    // s.SetOptions(server.TcpOptions{"aaaaaa", 2 * 1024 * 1024}) // Custom package EOF when the protocol is tcp
    s.Register(new(IntRpc))
