Problems with wordpress

[desarrolla2]

Hi for all.

I have the next code

 // any resource from wordpress.com
$resource  = 'http://lavidaestux.wordpress.com/tag/ubuntu/feed/';
$this->client = new \Guzzle\Http\Client();
$request = $this->client->get($resource);
$response = $request->send();

and i have the next error

Guzzle\Http\Exception\CurlException: [curl] 52: Empty reply from server [url] http://lavidaestux.wordpress.com/tag/ubuntu/feed/ [info] array (
'url' => 'http://lavidaestux.wordpress.com/tag/ubuntu/feed/',

Other servers works fine for me.

curl works fine from comand line

curl -I http://lavidaestux.wordpress.com/tag/ubuntu/feed/

Any ideas?

Hm. Very strange. This server does not respond to any request that contains the exact string and casing of "Guzzle" in the User-Agent header. For example, here's what the User-Agent header of a Guzzle request looks like:

User-Agent: curl/7.21.4 PHP/5.3.15 Guzzle/3.5.2

When I send a request with that header, I get an empty reply from the server. When I modify the User-Agent header to not include the term "Guzzle", I get a 200 OK response. Is it possible that this server has blacklisted the term Guzzle for some reason? I can reproduce this from the command line too:

$ curl -H "User-Agent: curl/7.21.4 PHP/5.3.15 Guzzle/3.5.2" -v http://lavidaestux.wordpress.com/tag/ubuntu/feed/
* About to connect() to lavidaestux.wordpress.com port 80 (#0)
*   Trying 76.74.254.123... connected
* Connected to lavidaestux.wordpress.com (76.74.254.123) port 80 (#0)
> GET /tag/ubuntu/feed/ HTTP/1.1
> Host: lavidaestux.wordpress.com
> Accept: */*
> User-Agent: curl/7.21.4 PHP/5.3.15 Guzzle/3.5.2
> 
* Empty reply from server
* Connection #0 to host lavidaestux.wordpress.com left intact
curl: (52) Empty reply from server
* Closing connection #0

I'd suggest contacting the host to see what the issue is. Have you been grabbing this feed too aggressively perhaps and they blocked you?

[desarrolla2]

I have not been aggressive, I've done less than 200 requests per day (a different worpress sub domains) to get RSS feeds...

Maybe other Guzzle User did.

[mtdowling]

Interesting. Well there's nothing I can do from my end. I suggest just changing your User-Agent header.

I have exactly the same issue when i use User-Agent : Guzzle/4.0

[desarrolla2]

@Spawnrad you need to customize user agent see here https://github.com/FastFeed/FastFeed/blob/master/src/FastFeed.php#L222

What the heck were Wordpress thinking. Just ran into this weird as hell bug. Will submit a report to them.

Update: they've unblacklisted Guzzle, so all should work as normal.
