[SOLVED] cURL Error #18?

TeraTask · #1 (**permalink**) 08-03-2007, 04:50 PM

OK. Here's one: I have the following code:

PHP Code:

  <?php
$content = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><methodCall><methodName>metaWeblog.getCategories</methodName><params><param><value><string>1</string></value></param><param><value><string>{USERNAME}</string></value></param><param><value><string>{PASSWORD}</string></value></param></params></methodCall>";

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDSIZE, strlen($content));
curl_setopt($ch, CURLOPT_POSTFIELDS,$content);
curl_setopt($ch, CURLOPT_URL,'{URL}');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // Don't stress about SSL validity
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

$headers[] = "Authorization: BASIC ".base64_encode('{USERNAME}:{PASSWORD}');
$headers[] = 'Content-type: application/xml';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result=curl_exec ($ch);
$curl_error = curl_error($ch);
$curl_error_no = curl_errno($ch);

if ($curl_error_no > 0) {
  $curl_error = curl_error($ch);
  $curl_error_no = curl_errno($ch);
  echo "cURL Error: (".$curl_error_no.") ".$curl_error;
} else {
  echo "Successfully retrieved: ".$result;
}
curl_close ($ch);
?>

Which works on most servers just fine to fetch the XML returned by WordPress for a category listing. On one server, though, I get this message:

cURL Error: (18) transfer closed with 1372 bytes remaining to read

I have searched and searched ( curl "transfer closed with" "bytes remaining to read" - Google Search ) and read and read and cannot find a hint as to what the hell is happening. Does anyone have a clue on this? If so, can you clue me in?

Thanks a ton in advance!!!!!

NOTE: You'd need to change {USERNAME}, {PASSWORD}, and {URL} to the appropriate values for testing. Due to confidentiality, I cannot release the URL where this is failing, but I can get server info if necessary.

Perhaps the server config might help. Also, do you know WHERE it is failing? That might help too.

What part of the server config? I don't have full access. I could get phpinfo(), but since I'd have to edit it to make it confidential, specific info needed would be helpful.

It's failing during the return. From what I was able to find out, the server is indicating that so many bytes of data will be sent but is not sending them all. cURL expects it to match and craps out with that message when they don't. I'm not sure how, or even if, that can be fixed.

OK... I got a bit frustrated and just coded a script to connect directly to the server. I sent

Code:

POST /xmlrpc.php HTTP/1.0
Host: mydomain.com
Content-Type: text/xml
Content-length: 288

<?xml version="1.0" encoding="UTF-8"?><methodCall><methodName>metaWeblog.getCategories</methodName><params><param><value><string>1</string></value></param><param><value><string>{USERNAME}</string></value></param><param><value><string>{PASSWORD}</string></value></param></params></methodCall>

and received

Code:


HTTP/1.1 200 OK
Date: Sat, 04 Aug 2007 09:30:11 GMT
Server: Apache/1.3.37 (Unix) PHP/5.2.3 mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 FrontPage/5.0.2.2635.SR1.2 mod_ssl/2.8.28 OpenSSL/0.9.7a
X-Powered-By: PHP/5.2.3

Content-Type: text/xml

No, I'm not missing the part after the Content-Type; the server is just not sending it. How is that even possible?

This has been in relation to WordPress. I got an idea last night just before crawling into bed to test this with a clean install of WP (no plugins or anything). A clean install worked just fine, so the client is adding the plugins back in one-at-a-time to see which caused it. I'll report back here when I have more.

Apparently it was none of the client's plugins - it was just a corrupted install of WordPress. I hope this helps someone in the future!
