如何使用curl正确发送和接收XML？

Question

我一直试图发布XML并从服务器获得响应,但没有运气.

以下是服务器端的条件:

• 对服务器的请求应通过HTTP 1.1以XML格式发送.

以下要求适用于HTTP请求:

• 请求类型应为POST;
• 甲Content-Length头应该存在,和该请求的总长度应低于16KB;
• 甲Content-Type头应该存在,包含媒体类型值text/xml;

这是我的脚本:

$url = "http://somedomain.com";
$xml = '<?xml version="1.0" encoding="UTF-8"?>
<Request PartnerID="asasdsadsa" Type="TrackSearch"> <TrackSearch> <Title>love</Title>    <Tags> <MainGenre>Blues</MainGenre> </Tags> <Page Number="1" Size="20"/> </TrackSearch> </Request>';
$header  = "POST HTTP/1.1 \r\n";
$header .= "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($xml)." \r\n";
$header .= "Connection: close \r\n\r\n"; 
$header .= $xml;
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);
$data = curl_exec($ch); 
echo $data;
if(curl_errno($ch))
    print curl_error($ch);
else
    curl_close($ch);

这给了我:

 HTTP Error 400. The request URL is invalid.
 Bad Request - Invalid URL

这有帮助吗？

<?php
$url = "http://stackoverflow.com";
$xml = '<?xml version="1.0" encoding="UTF-8"?><Request PartnerID="asasdsadsa" Type="TrackSearch"> <TrackSearch> <Title>love</Title>    <Tags> <MainGenre>Blues</MainGenre> </Tags> <Page Number="1" Size="20"/> </TrackSearch> </Request>';

$headers = array(
    "Content-type: text/xml",
    "Content-length: " . strlen($xml),
    "Connection: close",
);

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$data = curl_exec($ch); 
echo $data;
if(curl_errno($ch))
    print curl_error($ch);
else
    curl_close($ch);
?>
