php实现与python进行socket通信的方法示例

时间:2021-05-26

本文实例讲述了php实现与python进行socket通信的方法。分享给大家供大家参考,具体如下:

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; } } }}?>

multiServer.py

import threadingimport socketimport timeencoding = 'utf-8'BUFSIZE = 1024# a read thread, read data from remoteclass Reader(threading.Thread): def __init__(self, client): threading.Thread.__init__(self) self.client = client def run(self): #while True: data = self.client.recv(BUFSIZE) if(data): string = bytes.decode(data, encoding) print "from client::",string,"" time.sleep(10) self.client.send("return frome server::" + string) print "close:", self.client.getpeername() def readline(self): rec = self.inputs.readline() if rec: string = bytes.decode(rec, encoding) if len(string)>2: string = string[0:-2] else: string = ' ' else: string = False return string# a listen thread, listen remote connect# when a remote machine request to connect, it will create a read thread to handleclass Listener(threading.Thread): def __init__(self, port): threading.Thread.__init__(self) self.port = port self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) self.sock.bind(("0.0.0.0", port)) self.sock.listen(0) def run(self): print "listener started" while True: client, cltadd = self.sock.accept() print "accept a connect..." Reader(client).start() cltadd = cltadd print "accept a connect(new reader..)"lst = Listener(8888) # create a listen threadlst.start() # then start# Now, you can use telnet to test it, the command is "telnet 127.0.0.1 9011"# You also can use web broswer to test, input the address of "http://127.0.0.1:9011" and press Enter button# Enjoy it....
