来自 asp 页面的 XML 响应

2022-01-16 00:00:00 xml curl asp-classic php ajax

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

I have been trying to send xml message from php to asp and output response to my php page using CURL but having no luck in receiving any response. This is what I have tried:

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

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

"; 
$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))
    $output .= "
". curl_error($ch);
  }
else
    {curl_close($ch);}

echo $output;
?>

谁能指导我哪里错了?

推荐答案

不要为简单的 POST 构建自定义请求.CURL 完全有能力在没有所有这些恶作剧的情况下发帖:

Don't build a custom request for a simple POST. CURL is perfectly capable of doing a post without all those shenanigans:

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

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('xmlmessage' => $xml));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);

$result = curl_exec($ch);
if ($result === FALSE) {
    die(curl_error($ch));
}

echo $result
