php - socket_connect() : unable to connect [10061] - target machine actively refused it

Question

我正在尝试使用 PHP socket_connect() 函数连接用 C 编写的目标，但出现以下错误:

警告:socket_connect():无法连接[10061]:无法建立连接，因为目标机器主动拒绝。

这是我正在运行的代码:

    $service_port = 1234; 
    $address = "xx.xxx.xx.xxx";
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);     
    if ($socket === false) {
        echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
    } else {
        echo "OK.\n<br>";
    }       
    echo "Attempting to connect to '$address' on port '$service_port'...\n";        

    $result = socket_connect($socket, $address, $service_port);

    if ($result === false) {
        echo "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n";
    } else {
        echo "OK.\n<br>";
    }

我在 Windows 7 中使用带有 PHP 5.4 的 xampp 服务器并且我禁用了防火墙设置。我仍然收到相同的拒绝错误。

请帮我解决这个问题。 [过去 3 天我一直在与这个问题作斗争]

提前致谢。

如果您在同一台机器上运行客户端和服务器代码，那么您必须将它们混合起来，如下例所示:

<?php

//client

$host    = "localhost";
$port    = 80;
$message = "Hello Server";
echo "Message To server :".$message;
// create socket
$socket1 = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// connect to server
$result1 = socket_connect($socket1, $host, $port) or die("Could not connect to server\n");  


//server


// don't timeout!
set_time_limit(100);
// create socket
$socket2 = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// bind socket to port
$result2 = socket_bind($socket2, $host, $port) or die("Could not bind to socket\n");
// start listening for connections
$result2 = socket_listen($socket2, 3) or die("Could not set up socket listener\n");

// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket2) or die("Could not accept incoming connection\n");



// send string to server
socket_write($socket1, $message, strlen($message)) or die("Could not send data to server\n");


// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");
// clean up input string
$input = trim($input);
echo "Client Message : ".$input;
// reverse client input and send back
$output = strrev($input) . "\n";
socket_write($spawn, $output, strlen ($output)) or die("Could not write output\n");


$result1 = socket_read ($socket1, 1024) or die("Could not read server response\n");
echo "Reply From Server  :".$result1;

socket_close($spawn);
socket_close($socket2);
socket_close($socket1);
?>
