How does laravel call golang program through rpc

The following tutorial column will introduce to you how laravel calls golang programs through rpc. I hope it will be helpful to friends in need! Golang server

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)
    }}

PHP client

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));}

Return results

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