'NoSuchBucket' exception is thrown when an object doe…

[krwu]

$host   = explode('.', $request->getHost());
$bucket = (count($host) === 4) ? $host[0] : array_shift($path);
$object = array_shift($path);
if ($bucket && $object) {
    $data['code'] = 'NoSuchKey';
} elseif ($bucket) {
    $data['code'] = 'NoSuchBucket';
}

The host should be '{bucket}-{appid}.cos.{region}.myqcloud.com' for XML API. It means count(explode('.', $request->getHost()) equals 5, not 4(That's JSON API's value). This make $bucket always be array_shift($path), and $object always null;

I changed the condition from count($host) === 4 to count($host) >= 4. It could resolve #32.
