Question

我一直在尝试将php中的xml消息发送到asp并使用CURL将响应输出到我的php页面但是没有收到任何响应的运气。这就是我的尝试：

<?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 \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错在哪里吗？

Answer 1

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

交换双引号和单引号

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

单引号在xml标记中无效

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恶作剧的情况下发帖：

$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

来自asp页面的XML响应
