如何使用curl正确发送和接收XML？ [英] How to properly send and receive XML using curl?

问题描述

以下是服务器端的条件：

$

b
$ b

• 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;


• A Content-Length 标头应该存在，并且请求的总长度应低于16KB;


• A text / xml ;

<$ c> c $ c> Content-Type / ul>



这是我的脚本：

  $ url =http： /somedomain.com; 
 $ xml ='<？xml version =1.0encoding =UTF-8？> 
< Request PartnerID =asasdsadsaType =TrackSearch> < TrackSearch> < Title> love< / Title> < Tags> < MainGenre> Blues< / MainGenre> < / Tags> <页数=1大小=20/> < / TrackSearch> < / Request>'; 
 $ header =POST HTTP / 1.1 \r\\\
; 
 $ header。=Content-type：text / xml \r\\\
; 
 $ header。=Content-length：.strlen（$ xml）。\r\\\
; 
 $ header。=连接：关闭\r\\\
\r\\\
; 
 $ 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）; 
  

这给我：

  HTTP错误400.请求URL无效。 
错误请求 - 无效网址

 <？php

I've been trying to post XML and get response from the server but with no luck.

Here are the conditions on server side:

• Requests to the server should be sent as XML over HTTP 1.1.

The following requirements apply to the HTTP request:

• The request type should be POST;
• A Content-Length header should be present, and the total length of the request should be below 16KB;
• A Content-Type header should be present, containing the media type value text/xml;

Here is my script:

$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);

This gives me:

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

解决方案

Does this help?

<?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);
?>
