通过套接字从PHP发送消息到Python

Question

I'm trying to send a message to a Python socket using PHP and that it prints the message.

Here is the PHP code so far:

<?
$host = "localhost";
$port = 12345;

$f = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($f, SOL_SOCKET, SO_SNDTIMEO, array('sec' => 1, 'usec' => 500000));
$s = socket_connect($f, $host, $port);

$msg = "message";
$len = strlen($msg);

socket_sendto($f, $msg, $len, 0, $host, $port);

socket_close($f);
?>

And here is the Python one:

#!/usr/bin/python
# encoding: utf-8

import socket

s = socket.socket()
host = "localhost"
port = 12345
s.bind((host, port))

s.listen(5)
while True:
   c, addr = s.accept()
   print s.recv(1024)
   c.close()

But I'm getting the following error:

Traceback (most recent call last):
  File "server.py", line 15, in <module>
    print s.recv(1024)
socket.error: [Errno 107] Transport endpoint is not connected

I've also tried with socket_​sendmsg, socket_​write, fwrite and many more, but the error in Python is always the same, socket.error: [Errno 107] Transport endpoint is not connected.

It looks like I'm really lost.

Could anyone help me?

Thanks.

Try the following:

import socket

s = socket.socket()
host = "localhost"
port = 12345
s.bind((host, port))

s.listen(5)
while True:
   c, addr = s.accept()
   data = c.recv(1024)
   if data: print data
   c.close()

The main problem is your code was calling s.recv() when it should have been on c.recv(). Also make sure you check the data received (is it None?) before printing.
