I am wondering if anyone has successfully generated an EC2 v2 signature for their API using php. All examples/libraries I can find online are for v1 of the signature and that has been deprecated due to insecurities. An existing library that implements the signature generation would be appreciated too.

我相信那是V2

Here's a PHP Library that supports V2. I haven't tried it though.

使用常量 AWSSECRET 来散列签名,而不是 $AWSKEY(未引用的变量)。

这是我编写并一直在使用的一些代码:

define("AWSKEY", "Your AWS Key");
define("AWSSECRET", "Your AWS Secret");
public function get($parameters, $host) {

    // Build out the variables
    $domain = "https://$host/";
    $parameters['AWSAccessKeyId'] = AWSKEY;
    $parameters['Timestamp'] = date('c');
    $parameters['Version'] = '2007-11-07';
    $parameters['SignatureMethod'] = 'HmacSHA256';
    $parameters['SignatureVersion'] = 2;

    // Write the signature
    $signature = "GET\n";
    $signature .= "$host\n";
    $signature .= "/\n";

    $sigparams = $parameters;

    ksort($sigparams);

    $first = true;
    foreach($sigparams as $key=>$param) {
        $signature .= (!$first ? '&' : '') . rawurlencode($key) . '=' . rawurlencode($param);
        $first = false;
    }
    $signature = hash_hmac('sha256', $signature, $AWSKEY, true);
    $signature = base64_encode($signature);
    $parameters['Signature'] = $signature;

    $url = $domain . '?';
    $first = true;
    foreach($parameters as $key=>$param) {
        $url .= (!$first ? '&' : '') . rawurlencode($key) . '=' . rawurlencode($param);
        $first = false;
    }

    $ch = curl_init(trim($url));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    $output = curl_exec($ch);

    return $output;

}

下面是你如何使用它:

$params = array(
    'Action' => 'ListDomains'
);
$db->get($params, 'sdb.amazonaws.com');

ListDomains这将在 SimpleDB 上执行查询。该函数本身将返回 Amazon 的输出。对于更复杂的命令(即:PUT、POST 等),不需要进行任何重大修改。
