我正在尝试使用github.com/dullgiulio/pingo
并发送我的自定义结构
type LuaPlugin struct {
Name string
List []PluginTable
}
type PluginTable struct {
Name string
F lua.LGFunction
}
// LoadPlugins walks over the plugin directory loading all exported plugins
func LoadPlugins() {
//
p := pingo.NewPlugin("tcp", "plugins/test")
// Actually start the plugin
p.Start()
// Remember to stop the plugin when done using it
defer p.Stop()
gob.Register(&LuaPlugin{})
gob.Register(&PluginTable{})
var resp *LuaPlugin
// Call a function from the object we created previously
if err := p.Call("MyPlugin.SayHello", "Go developer", &resp); err != nil {
log.Print(err)
} else {
log.Print(resp.List[0])
}
}
但是,我总是得到nil
ym struct的F
字段。这是我在客户端上发送的内容
// Create an object to be exported
type MyPlugin struct{}
// Exported method, with a RPC signature
func (p *MyPlugin) SayHello(name string, msg *util.LuaPlugin) error {
//
//
*msg = util.LuaPlugin{
Name: "test",
List: []util.PluginTable{
{
Name: "hey",
F: func(L *lua.LState) int {
log.Println(L.ToString(2))
return 0
},
},
},
}
return nil
}
是否无法通过RPC发送自定义数据类型?

我对库不熟悉,但是您可以尝试在传输之前将结构转换为字节片。延迟回复可能会对其他人有所帮助。...
简单转换:以字节为单位返回结构
func StructToBytes(s interface{}) (converted []byte, err error) {
var buff bytes.Buffer
encoder := gob.NewEncoder(&buff)
if err = encoder.Encode(s); err != nil {
return
}
converted = buff.Bytes()
return
}
解码器:返回一个包装器,将字节解码为
func Decoder(rawBytes []byte) (decoder *gob.Decoder) {
reader := bytes.NewReader(rawBytes)
decoder = gob.NewDecoder(reader)
return
}
示例:
type MyStruct struct {
Name string
}
toEncode := MyStruct{"John Doe"}
// convert the struct to bytes
structBytes, err := StructToBytes(toEncode)
if err != nil {
panic(err)
}
//-----------
// send over RPC and decode on other side
//-----------
// create a new struct to decode into
var DecodeInto MyStruct
// pass the bytes to the decoder
decoder := Decoder(structBytes)
// Decode into the struct
decoder.Decode(&DecodeInto)
fmt.Println(DecodeInto.Name) // John Doe
由于使用了gob软件包,您可以在一定程度上交换类型和类型转换。
