在PHP中使用curl发布文件时出现问题

Question

I'm trying to post a file with curl in php, but the file is never uploaded/accepted by the server. I have searched and tried for several hours, but I can't find whats wrong, everyone elses examples and codes seems to work, but not this one.

Here is the code:

<?php

$url = "http://jpptst.ams.se/0.52/default.aspx";
$headers = array(
        "Content-Type: text/xml; charset=iso-8859-1",
    "Accept: text/xml"
);

$data = array("file" => "@documents/xmls/1298634571.xml");

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, false);

curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);

curl_close($ch);

var_dump($response);

?>

The result I get:

string(904) "HTTP/1.1 100 Continue

HTTP/1.1 200 OK
Date: Mon, 25 Jul 2011 19:13:41 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 659"

Thats all I get.. the file is never accepted by the server. If anyone can help me with this problem it would be much appreciated :) Thanks!

Answer 1

You're trying to upload a file via HTTP post, so sending a Content-type: text/xml header is inappropriate. An HTTP file upload is actually done as multipart/form-data , and is actually pretty much identical to a MIME-encoded email attachment. PHP's curl will fill in the header details for you automatically. As well, the Accept header is not necessary either.

Check that the path to the .xml file you're trying to upload is correct. You've not specified a leading / to it, so the path is relative to where your PHP script is executing from.

Replace:

$data = array("file" => "@documents/xmls/1298634571.xml");

With this:

$data = array("file" => "@".realpath('documents/xmls/1298634571.xml'));

Try it, might work, i'm not sure tho.

EDIT:

Try this out:

<?php 

$xmldatafile="documents/xmls/1298634571.xml"; // Make sure the file path is correct

function postData($postFields,$url){ 
                $ch = curl_init(); 
                curl_setopt($ch, CURLOPT_URL, $url); 
                curl_setopt($ch, CURLOPT_POST ,1); 
                curl_setopt($ch, CURLOPT_POSTFIELDS ,$postFileds); 
                curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,1); 
                curl_setopt($ch, CURLOPT_HEADER ,0); 
                curl_setopt($ch, CURLOPT_RETURNTRANSFER ,1); 
                $data = curl_exec($ch); 
                curl_close($ch); 
                return $data; 
} 

$xmlData = file_get_contents($xmldatafile); 

$postFileds = 'data='.$xmlData; 


$result = postData($postFields,"http://jpptst.ams.se/0.52/default.aspx"); 
?>
