class.s3.php

It may be a good idea to add an additional function for query based auth. Here is one I made:

function createURL($bucket, $object, $time) {

$key = $this->key; $secret = $this->secret; $server = $this->server;

$expires = time() + $time;

$str = "GET\n\n\n" . $expires . "\n" . '/' . $bucket . '/' . $object;

$sha1 = $this->hasher($str); $sig = $this->base64($sha1); $sig = rawurlencode(trim($sig));

$url = $server . '/' . $bucket . '/' . $object . '?AWSAccessKeyId=' . $key . '&Expires=' . $expires . '&Signature=' . $sig;

return $url;

}

where can i download this class?

If I use:

"$PATH"

for $disposition on the putObject method, when I download the file I get:

__usr_local_bin__usr_local_sbin__bin__sbin__usr_bin__usr_sbin__usr_X11R6_bin_

wich is a BIG security violation.

Should my application handle this or should this be part of the class?

I'm new in OOP. Thanks

I'm interested on participating on this project.

Here is a quick solution I did to fix this problem:

	function sendRequest($req, $params = null)
	{
		if(isset($req['resource']))
		{
			$req['resource'] = urlencode($req['resource']);
			$req['resource'] = str_replace("%2F", "/", $req['resource']);
		}

		$sig = $this->signature($req);

		$args = array();
		$args[] = array("-H", "Date: " . $this->_date);
		$args[] = array("-H", "Authorization: AWS {$this->_key}:$sig");

		if(isset($req['acl'])) $args[] = array('-H', 'x-amz-acl: ' . $req['acl']);
		if(isset($req['type'])) $args[] = array('-H', 'Content-Type: ' . $req['type']);
		if(isset($req['md5'])) $args[] = array('-H', 'Content-Md5: ' . $req['md5']);
		if(isset($req['disposition'])) $args[] = array('-H', 'Content-Disposition: attachment; filename="' . $req['disposition'] . '"');
		if(isset($req['upload'])) $args[] = array('-T', $req['upload']);

		if(is_array($req['headers']))
			foreach($req['headers'] as $key => $val)
				$args[] = array('-H', "$key: $val");

		if(strtolower($req['verb']) != "head")
			$args[] = array("-X", $req['verb']);

		$curl = $this->_pathToCurl . " -s ";
		foreach($args as $arg)
		{
			list($key, $val) = $arg;
			$curl .= $key . ' ' . escapeshellarg($val) . ' ';
		}

		$curl .= '"' . $this->_server . $req['resource'];

		if(is_array($params))
		{
			$curl .= "?";
			foreach($params as $key => $val)
				$curl .= "$key=" . urlencode($val) . "&";
		}

		$curl .= '"';

		if(strtolower($req['verb']) == "head")
			$curl .= " -I ";

		if(isset($req['download'])) $curl .= ' -o "' . $req['download'] . '"';

		return `$curl`;
	}

Basically I used single quotes to set the values of the $args array since variables within singles quotes are not parsed by PHP (see variable parsing), and escapeshellarg to set the arguments for the curl comand.

Amazon AWS, your links are broken. There's nowhere to go to download this class, or any other php files as far as I can tell.

http://php-aws.googlecode.com/svn/trunk/class.s3.php

The links aren't broken. You should look better ;) You should go to Source -> Subversion repository -> trunk -> class.s3.php

You might want to add $curl .= " -m 60 " and limit your curl down to 60 seconds.

It happened several times already that curl never returned (not even after 12 hours.)I'm uploading tens of thousands of files a day, so I have better chances of this happening :)

How can I create a multi-tier bucket? I am trying to mirror my local file system on a server, and would love to be able to create buckets to mimic something like this:

'/assets/images/icons/'

Anyone have any idea?

Name your object as the whole path. For instance: object name is: '/assets/images/icons/foo.gif'

Amazon as a max of 100 buckets anyway, so you could not mimic your file system

Is there anyway to get debugging info? I'm having some problems and can't seem to trace the source of the error....

is there a way to copy an object without downloading it? i found this http://doc.s3.amazonaws.com/proposals/copy.html but am not sure if amazon has this functionality enabled yet

I have extensively revised this class to address issues 11 and 19, and to make the following changes:

Tidying of sendRequest and signature to make them more consistent Some removal of redundant code Addition of getBucketACL() method to retrieve copy of access control policy Allow objects to be created with any ACP, not just public-read Allow buckets to be created with EU Location constraint Validation of location and ACP parameters Modified getLocation() to remove hack and use new standardised method for query string parameters.

Tyler - if you're interested in using it, let me know.

As gil.megidish said, you better add -m 60 to $curl or the number of seconds you consider right for your application to prevent curl to hang indefinitely. It happened to me several times and curl not returning was in fact breaking my application.
