php之与python进行socket通信

来源：互联网发布：北京python工程师工资编辑：程序博客网时间：2024/05/20 06:55

## 设计目的

通过前端页面发起请求交给php，php创建socket请求交给python脚本，然后执行完毕之后，返回给前端。

## index.html

<html><head><title>test</title><script>g_xmlHttpReq = new XMLHttpRequest();function onReplyCallback(){if(g_xmlHttpReq.readyState==4 && g_xmlHttpReq.status==200){alert(g_xmlHttpReq.responseText);}}function on_stop_service(){g_xmlHttpReq.open("GET","./service/main.php?cmd=1",true);g_xmlHttpReq.onreadystatechange=onReplyCallback;        g_xmlHttpReq.send(null);}</script></head><body><button onclick="on_stop_service()">关闭服务</button></body></html>

## service / main.php

<?phprequire_once('mysocket.php'); $con = Connector::getInstance();$req = "aaaaaaa";$con->sendMsg($req);$ret = $con->getMsg();echo $ret;?>

## service / mysocket.php

<?phpclass Connector{public static $instance=null;public $conn;private function __construct(){set_time_limit(0);$ip = '192.168.238.1';$port = 8888;if(($this->conn = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {echo "socket_create() 失败的原因是:".socket_strerror($this->conn)."\n";}$result = socket_connect($this->conn, $ip, $port);if ($result < 0) {    echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n";}else {    echo "连接OK\n";}}public static function getInstance(){if(is_null(self::$instance)){self::$instance = new Connector;  }return self::$instance;}public function sendMsg($msg){socket_write($this->conn,$msg);}public function getMsg(){$clients = array($this->conn);while(true){$read = $clients;$wrSet = NULL;$errSet = NULL;if(socket_select($read, $wrSet,$errSet, 3) < 1){continue;}foreach($read as $read_sock){$data = @socket_read($read_sock,1024,PHP_BINARY_READ);socket_close($this->conn);return $data;}}}}?>
