laravel怎么通過rpc調用golang程序

package mainimport (     "fmt"     "net"     "net/rpc"     "net/rpc/jsonrpc")type Goods struct{}//方法（必須是公有方法，且必須是兩個參數）func (g *Goods) GetName(args string , res *string) error {     *res = "args=" + args    return nil}func main() {      //注冊rpc服務,并自定義服務名     err := rpc.RegisterName("Goods",new(Goods))     if err != nil {         panic(err.Error())     }      //監聽端口，如果監聽所有客戶端則去掉ip     listen, err := net.Listen("tcp", "127.0.0.1:7081")     if err != nil {         panic(err.Error())     }      fmt.Println("啟動服務...")      for {         conn, err := listen.Accept() // 接收客戶端連接請求         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('鏈接失敗');       }        $method = 'Goods.GetName';       $params = "我是字符串參數";       $err = fwrite($conn, json_encode(array(               'method' => $method,               'params' => [$params],               'id' => 0,           ))."n");      if ($err === false){          dd('寫入數據失敗');       }       stream_set_timeout($conn, 0, 30000);//超時配置      $line = fgets($conn);      if ($line === false) {          dd('獲取響應數據失敗');       }      dd(json_decode($line,true));}

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