向套接字发送 XML 请求

Question

我正在尝试通过 TCP\IP（套接字）连接将 XML 发送到服务器。

我的连接正常。发送部分是问题。

见下文；

<?php

error_reporting(E_ALL);
ini_set('display_errors', 1);

$host    = "xx.xxx.xx.xxx";
$port    = xxxx;

// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");

// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");
if($result === true){
    echo 'connected';
} 

$sendVendRequest='
<ipayMsg client="SAFEPAY" term="00001" seqNum="0" time=" '.date('Y-m-d   H: i: s').' +0200">
    <elecMsg ver="2.44">
        <vendReq>
            <ref>319155500001</ref>
            <amt cur="KSh">1000</amt>
            <numTokens>1</numTokens>
            <meter>A12C3456789</meter>
            <payType>cash</payType>
        </vendReq >
    </elecMsg>
</ipayMsg>';


$vendRequestXml=simplexml_load_string($sendVendRequest) or die("Error: could not create an object");
// print_r($vendRequestXml);
socket_write($socket, $sendVendRequest, strlen($sendVendRequest)) or die("Could not send data to server\n");

发送部分失败。它加载直到超时。我怀疑我错误地发送了请求。请有人指导我如何实现这一点。

这段代码对我有用：

<?php

error_reporting(E_ALL);
ini_set('display_errors', 1);

$host    = "example.com";
$port    = 80;

// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");

// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");
if($result === true){
    echo 'connected';
}·

$st='
<ipayMsg client="SAFEPAY" term="00001" seqNum="0" time=" '.date('Y-m-d   H: i: s').' +0200">
    <elecMsg ver="2.44">
        <vendReq>
            <ref>319155500001</ref>
            <amt cur="KSh">1000</amt>
            <numTokens>1</numTokens>
            <meter>A12C3456789</meter>
            <payType>cash</payType>
        </vendReq >
    </elecMsg>
</ipayMsg>';


$length = strlen($st);

while(true) {
  $sent = socket_write($socket, $st, $length);

  if($sent === false) {
    break;
  }

  // Was the entire msg sent?
  if($sent < $length) {
    // If not, handle the leftover data.
    $st = substr($st, $sent);
    $length -= $sent;
  } else {
    break;
  }
}

echo socket_read($socket, 8192);

你能远程上网到那个端口吗？
