PHP 上的 XML 响应

Question

可能的重复：
来自 asp 页面的 XML 响应

我一直在尝试将xml消息从php发送到asp并且使用 CURL 将响应输出到我的 php 页面，但没有收到任何响应。这就是我尝试过的：

<?php

$post_string = "xmlmessage=<?xml version='1.0' encoding='UTF-8'?>
$url = "https://someweb.asp"; 
<abc>
<UserId>123</UserId> 
</abc>";

//$header  = "POST HTTPS/1.0 \r\n";
$header = "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Connection: close \r\n\r\n"; 
$header .= $post_string;

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

$output = curl_exec($ch);
$info = curl_getinfo($ch);

if ($output == false || $info['http_code'] != 200) {
  $output = "No cURL data returned for $url [". $info['http_code']. "]";
  if (curl_error($ch))
    $output .= "\n". curl_error($ch);
  }
else
    {curl_close($ch);}

echo $output;
?>

任何人都可以指导我哪里错了吗？

尝试：

<?php
//do not put the $url within the XML (like in your original post)
$url = "https://someweb.asp"; 

$post_string =<<<XML
<?xml version='1.0' encoding='UTF-8'?>
<abc>
<UserId>123</UserId> 
</abc>
XML;

$post_string='xmlmessage='.rawurlencode($post_string);
echo $post_string;

/*
//$header  = "POST HTTPS/1.0 \r\n";
$header = "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Connection: close \r\n\r\n"; 
$header .= $post_string;
*/

$ch = curl_init($url);


curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);

//get rid of the following and use the POST headers    
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

//add the following two headers (for POST requests)
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post_string);

$output = curl_exec($ch);
$info = curl_getinfo($ch);

if ($output == false || $info['http_code'] != 200) {
  $output = "No cURL data returned for $url [". $info['http_code']. "]";
  if (curl_error($ch))
    $output .= "\n". curl_error($ch);
  }
else
    {curl_close($ch);}

echo $output;
?>
