	// Trace trace
	func Trace(name string, param ...interface{}) func() {

	start := time.Now()

	return func() {

ruandao / connector.go

Created July 6, 2018 10:05

rpc call err: gob: type not registered for interface: map[string]interface {} 原因是： args 里面一个字段是interface{}, 然后赋值的时候，赋值为map[string]interface{} 结果就跪了一天。。。。

	args := BussinessRPC.ProcessMsg{
	UserId: cor.userId,
	Message: message,
	TimeStamp: time.Now().Format("2006-01-02 15:04:05.000"),
	}
	reply := &BussinessRPC.ProcessMsgReply{}

	service := "FreeStyleGame.Process"
	conn, err := rpc.Dial("tcp", address)

ruandao / x.go

Created July 6, 2018 10:12

2018/07/06 18:10:51 call err: gob: type not registered for interface: map[string]interface {} panic: call err: gob: type not registered for interface: map[string]interface {} 确定原因是，map赋值给interface{}字段也就是说，rpc调用不支持interface{}字段咯

	package main

	import (
	"net/rpc"
	"log"
	"fmt"
	)

	func failOnErr(err error, s string) {
	if err != nil {
