Golang和php通訊

不一樣語言之間的通訊方式有不少種,這裏我介紹一種最簡單通訊方式,json-rpc。php

Golang自帶json-rpc包,使用起來十分簡單,示例以下,提供一個簡單echo server。golang

package main

import (
	"fmt"
	"net"
	"net/rpc"
	"net/rpc/jsonrpc"
)

type Serve struct {

}

func (s *Serve) Echo(a *int, r *int) error {
	*r = 1
	return nil
}

func main() {
	tcpAddr, err := net.ResolveTCPAddr("tcp", ":9001");
	if err != nil {
		fmt.Println(err)
		return
	}

	l, err := net.ListenTCP("tcp", tcpAddr)
	if err != nil {
		fmt.Println(err)
		return
	}

	serve := &Serve{}
	rpc.Register(serve)
	for {
		conn, err := l.Accept()
		if err != nil {
			fmt.Println(err)
			continue
		}
		go jsonrpc.ServeConn(conn)
	}
}

php 客戶端代碼,示例以下。json

$conn = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if (!$conn) {
    return FALSE;
}
socket_set_option($conn, SOL_SOCKET, SO_SNDTIMEO, array(
    "sec" => 0,
    "usec" => 50000
));
$result = socket_connect($conn, '127.0.0.1', 9001);
$s = time();
$w = ['id' => time(), 'params' => [1], 'method' => 'Serve.Echo'];

socket_write($conn, json_encode($w));
$r = socket_read($conn, 1024);
socket_close($conn);

echo $r;

就這樣。架構
