php-golang-rpc 简单的jsonrpc实践
golang代码：
package main

"net"
"net/rpc"
"net/rpc/jsonrpc"
)
type App struct{}
type Res struct {
Code int `json:"code"`
Msg string `json:"msg"`
Data any `json:"data"`
}

res.Code = 200
res.Msg = "成功"
var rmp = make(map[string]any, 0)
if v, ok := mp["name"].(string); ok {
rmp["name"] = "my name is " + v
} else {
rmp["name"] = "my name is unknown"
}
res.Data = rmp
return nil
}
func main() {
ln, err := net.Listen("tcp", ":6001")

for {
conn, err := ln.Accept()
if err != nil {
continue
}
go func(conn net.Conn) {
jsonrpc.ServeConn(conn)
}(conn)
