我正在尝试创建授权签名以访问 IAM 安全 API 网关端点。

$alg = "SHA256";
$CanonicalRequest = "GET\n/dev/pets\n\nhost:3r4fgts8e5.execute-api.ap-northeast-1.amazonaws.com\nx-amz-date:".$dd."\n\nhost;x-amz-date\ne3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855";

$CR =  str_replace("\n", "", $CanonicalRequest);
            $CR = str_replace("\r", "", $CR);
            $CR = strtolower($CR);




$StringToSign  = "AWS4-HMAC-SHA256\n".$dd."\n".$date->format( 'Ymd' )."/ap-northeast-1/execute-api/aws4_request\n".hash( $alg, $CR )."";





// 1) HMACs
$kSecret = 'AWS4' . $secret_key;
$kDate = hash_hmac( $alg, $date->format( 'Ymd' ), $kSecret, true );     
$kRegion = hash_hmac( $alg, $region, $kDate, true );
$kService = hash_hmac( $alg, $service, $kRegion, true );
$kSigning = hash_hmac( $alg, 'aws4_request', $kService, true );     
$signature = hash_hmac( $alg, $StringToSign, $kSigning …
