laravel怎么通过rpc调用golang程序

package mainimport (     "fmt"     "net"     "net/rpc"     "net/rpc/jsonrpc")type Goods struct{}//方法（必须是公有方法，且必须是两个参数）func (g *Goods) GetName(args string , res *string) error {     *res = "args=" + args    return nil}func main() {      //注册rpc服务,并自定义服务名     err := rpc.RegisterName("Goods",new(Goods))     if err != nil {         panic(err.Error())     }      //监听端口，如果监听所有客户端则去掉ip     listen, err := net.Listen("tcp", "127.0.0.1:7081")     if err != nil {         panic(err.Error())     }      fmt.Println("启动服务...")      for {         conn, err := listen.Accept() // 接收客户端连接请求         if err != nil {             continue         }          go jsonrpc.ServeConn(conn)     }}

public function test(){       $host = '127.0.0.1';       $port = '7081';        $conn = fsockopen($host, $port, $errno, $errstr, 3);       if (!$conn) {           dd('链接失败');       }        $method = 'Goods.GetName';       $params = "我是字符串参数";       $err = fwrite($conn, json_encode(array(               'method' => $method,               'params' => [$params],               'id' => 0,           ))."n");      if ($err === false){          dd('写入数据失败');       }       stream_set_timeout($conn, 0, 30000);//超时配置      $line = fgets($conn);      if ($line === false) {          dd('获取响应数据失败');       }      dd(json_decode($line,true));}

array:3 [   "id" => 0   "result" => "args=我是字符串参数"   "error" => null]
